Ipl Strenght and Weakness Essay Example

Ipl Strenght and Weakness Essay The bidding process for the eight franchises that will compete in the Indian Premier League has officially begun with the release of the prospectus for the inaugural Twenty20 competition beginning in April 2008. The tender inviting bids for the franchises will be announced sometime in December. Potential franchisees can submit bids for more than one city-team and must state the total fee they are offering for a franchise for the first ten-year term. The auction of players will immediately follow the awarding of the franchises. The prospectus also laid out the manner in which the IPLs revenue would be shared with the franchises. The franchises will receive 80% of the television revenue over the first two years, 70% in the third and fourth years, 60% between years five and ten, and 50% from the 11th year onwards. In addition, they will also receive 60% of the sponsorship revenue during the first ten years, after which they will receive 50%. Of the total amount to be distributed, 20% will be divided based on the final league positions of the franchises while the other 80% will be shared squally. The IPLs distribution model, which is based on their current forecasts for the first contracts for centralized television and sponsorship agreements, should be adjusted should the forecasts change. The competition comprises 59 matches and spans 44 days with each franchise playing the other on a home and away basis. The top four teams qualify for the semi-finals, the winners of which will contest the final. The two finalists will in turn qualify for the Champions Twenty20 tournament, which has been provisionally scheduled for October 2008.

Four Under-21 players and four players from the franchises catchment area must also be part of the squad, though these can be the same players. Our first round-up of the IPLs finances shows the league generated $209 million in revenue in its second season, for an aggregate operating profit (earnings before interest, taxes and depreciation) of $89 million. The average franchise is worth $67 million, a 31% increase in just one year. The Rajasthan Royals, winners of the leagues first championship, has risen in value by 71%. This despite the uncertainty and logistical headaches caused by moving this years entire 59-game slate, including the final, to South Africa with only three weeks notice. (After terror incidents, the Indian government was anxious about providing security as parliamentary elections coincided with the month-long season. The IPL was conceived in 2007 near some hallowed ground for sports: in Londons Wimbledon suburb. There, Lalit Modi, representing the Board of Control for Cricket in India (BCCI), the governing body of Indian cricket, and Andrew Wildblood, an executive at sports management powerhouse IMG, discussed the disconnect between crickets worldwide popularity and the lack of commercial success of any domestic league. Their solution: a franchise ownership structure modeled after top U. S. sports leagues. Since then , the league has grown at breakneck speed. In January 2008, eight IPL teams were auctioned for a combined $724 million (to be paid in 10 annual installments to the nonprofit BCCI, an umbrella for the IPL). Just three months later, the Redskins First Ladies of Football were flown in to shake their pom-poms at the sold-out opener. Proceeds from the auction, as well as portions of national media and sponsorship deals, are reinvested, mostly in Indias aging (as far back as the 19th century) cricket stadiums, including some of the 10 rented by IPL teams for $100,000 per match. How successful was that first season? The 2008 semifinals and final drew 62 million viewers in India, with a per-match average of 11% of the nations total cable audience. In the months that followed, Modi, now IPL commissioner, opted out of TV deals with Sony and World Sports Group, risking nearly $1 billion of guaranteed payments over the next nine years. The gamble paid off, to the tune of a 98% annual increase from those broadcast partners, both of which deemed the IPL too valuable a property to lose. One reason the league is so TV-friendly is its format: Matches are held under Twenty20 rules that speed up each contest to about three hours (a traditional cricket match can last days, with tea breaks). The format is sweeping cricket worldwide. Revenue from TV, mobile and digital rights deals totaled $100 million for the latest season, of which teams split an 80% share equally. They also divvied up 60% of the $40 million in league sponsorships, including a cool $10 million from the leagues title sponsor, DLF, Indias largest real estate firm, and $5. million from motorbike maker Hero Honda. Despite playing 5,000 miles away, Indian companies actually increased spending on team sponsorships, which grew by 60% to a collective $60 million. Ground staff scurried to change signage before every match so that none of the floating teams advertisers were underrepresented. Ticket sales did not go as smoothly. The move led to a 75% drop in gate receipts, as prices were slashed to fill up stadiums to make the product more appealing on TV. That must have worked: This year, the finals telecast reached 24% more viewers in India than in 2008. Even Modi is surprised by how quickly the league has grown. At the beginning there were not many bidders who were conscious of the fact that the league would succeed, and they had to bid on total blind faith. There was no history, everybody was writing against it, there was no support for it, he says. Then the first season averaged 58,000 fans per match (80% more than a typical Major League Baseball game), and new investors clamored to climb aboard. In February, an ownership group that includes Lachlan Murdoch, the son of media baron Rupert Murdoch, sold a minority stake in the Rajasthan Royals to investors fronted by actress Shilpa Shetty in a deal that reflected the rapid value appreciation. Just last year, the Royals were auctioned for a league-low $67 million over 10 years. While speculation about the IPLs long-term viability drove prices down at the franchise auction, the leagues early success has now translated to unrealistic valuations in the other direction. Not helping is a misguided study frequently cited by cricket officials that calls the IPL a $2 billion business. Perhaps one day, but certainly not yetour cumulative valuation amounts to barely one-fourth of that. Our survey of franchise values is determined by multiples of revenue from continuing operations, except in cases where teams are on the verge of gaining additional money and exposure. Example: The Delhi Daredevils will play for a share of a $6 million purse in the inaugural Twenty20 Champions League this fall, on top of receiving $500,000 just for participating in the tournament. Since up to half of team revenue is accrued by dint of gate receipts, local sponsorships and merchandisingrevenue streams of which teams share little with the leaguemarket size plays a major role in making some franchises more valuable than others. Take the Mumbai Indians, who play before a robust corporate base in Indias largest city. The Indians are the IPLs most valuable team, worth $80 million for the owner, oil and gas giant Reliance Industries and company chairman and largest shareholder Mukesh Ambani, Indias wealthiest man. Sensing Mumbai as the IPLs signature brand, akin to the English footballs Manchester United or baseballs New York Yankees, companies from outside of India, like Adidas ( ADDDY. PK news people ) and MasterCard ( MA news people ), have been quick to sponsor the team. Over two seasons, Mumbais $43 million in revenue tops the IPL. Some of the IPLs cachet comes from its owners: Khan uses the resources of his film company, Red Chillies Entertainment, to promote Kolkata and expand the teams reach into new markets. His strategy is paying off. Polls consistently rank the Knight Riders as Indias most popular team, and theyre already more valuable than two teams that were sold at higher auction prices only a year and a half ago. Such hands-on management is a far cry from the Stanford Super Series, the defunct Twenty20 competition between the English national team and all-stars from around the West Indies that was bankrolled by alleged Ponzi schemer R. Allen Stanford and thought to be competition for the IPL. Instead, after only one year, the SSS joined an alphabet soup of failed cricket ventures, including the IISC, WSC and APC. Cricket has been played internationally for 165 years and was once a contest at the Olympics. With 104 nations as members of crickets governing body, its one of the most popular sports in the world. But before the IPL, professional leagues had never truly been run as a business. Most leagues around the world are operated by nonprofit entities and teams owned by athletic clubs with thousands of members; often, making money is a low priority. Says Donald Lockerbie, chief executive of the USA Cricket Association, [English cricket] is as traditional a sport as there is. Its essentially a club membership drive. National teams have always been crickets top draw. But private franchise ownership coupled with the commercial possibilities of the new, abbreviated version of the game in Indias cricket crazed marketplace has upended the sports established order. Its also made Modi into crickets most influential (if polarizing) figure, for whom profit always trumps tradition. A brash and charismat ic promoter, hes the subcontinents answer to Don King. In April he hired around-the-clock security after reportedly receiving death threats from the mob, the gambling operations of which stood to take a hit from the season moving to South Africa. Unfazed, Modi is already laying the groundwork for the IPLs next chapter. We plan to have another shorter [season] that will move around the world, with a main league that will stay in India, he says. Another plan to boost league coffers is to add more teams. IMGs Wildblood projects expansion as early as 2011 with the IPL adding one or two more squads. Unlike in the early days, bidders will have a sense of the leagues long-term prospects. I think a lot of people discounted the fact that there was any value, Modi says. Not anymore.

First Day Jitters Picture Book About Starting School

First Day Jitters Picture Book About Starting School First Day Jitters is an excellent book for an elementary school student (or first-time teacher) who is apprehensive about starting school. This humorous picture book was written by Julie Danneberg. Artist Judy Love created the comic and colorful illustrations in ink and watercolors. This is a funny book, with a surprise ending that will cause the reader to laugh out loud and then go back and read the entire story again. Kids starting middle school also find First Day Jitters amusing. A Story With a Twist Its the first day of school and Sarah Jane Hartwell does not want to get ready because she will be going to a new school. In fact, Sarah doesnt even want to get out of bed. When Mr. Hartwell tells her its time to get ready for school, she says, Im not going. Sarah complains that she hates her new school, I dont know anybody, and it will be hard, and...I just hate it, thats all. After much discussion, and no help from the familys feuding dog and cat, Sarah gets ready for school. By the time, Mr. Hartwell drops her off at school, she is terrified, but the principal greets her at the car and walks Sarah to her classroom. It is only on the last page  when Sarah is introduced to the class that the reader discovers that Sarah is not a student but the new teacher! The Author and Illustrator Author Julie Danneberg and illustrator Judy Love have continued the story of new teacher Sarah Jane Hartwell in the picture books First Year Letters (2003), Last Day Blues (2006), The Big Test (2011) and Field-Trip Fiasco (2015). First Day Jitters is also available in a Spanish edition Que Nervios! El Primer Dia de Escuela Julie Danneberg is a graduate of the University of Colorado, Boulder. She is a middle school teacher and the author of picture books for younger children and nonfiction for older children.

Interpersonal Skills for Work Place Essay Example | Topics and Well Written Essays - 1000 words

Interpersonal Skills for Work Place - Essay Example The nature of interpersonal communication is dynamic because it cannot be explained or generalized easily. People are extremely different and therefore there is no one theory that can inform managers about how to behave in the workplace. Each situation has to be assessed individually and then judgement should be made accordingly. The aim should be to maximize the benefit of the organization and gain maximum out of the employees. The theoretical framework explaining effective interpersonal skills can only be used as a guideline. It is based upon general principles that are aimed at effective listening and communication of thoughts. It is also vital not to overreact but at the same time digression should be avoided at all cost. Such basic techniques can improve interpersonal skills at the workplace.Analysis of Team MembersIn the meeting there are different team members. First of all it is important to clearly define roles of chairperson and care manager. Then direction of the housing a ssociation is to be set. It is extremely important to shape the conversation on the right track otherwise no conclusive thing will come out of such meetings. It is also important to understand the behavioural cues of the team members. In face to face encounters on average 55% of communication is done through body language and only 7 % is communicated through words (Donnelley & Neville, 2008). This is why team members that are not speaking may be contributing to the meeting. It is therefore important to understand their point of view as well.

Disintermediation in Tourism Essay Example | Topics and Well Written Essays - 1000 words - 1

Disintermediation in Tourism - Essay Example The impacts of disintermediation are various. It has impacted the travel and tourism industry significantly. The supply chain of travel and tourism industry involves tour operators, travel agencies, travel agents and others. Traditionally prospects and people have been depended on these mediators largely for their information and booking needs. Development of web technologies helped the service providers in travel and tourism industry such as airlines, car rentals, hotels and others to offer their services and information through their website. In the image below (Image 1) of WTO 2001 report on E-Business for Tourism, it clearly presents the number of intermediaries which are replaced by the Internet. However, it is evident that these intermediaries co-exist with the internet even in the countries where the internet users are high in number. The use and growth of website services depend on the number of factors like number of internet users, technological platforms available and many others. There are various reasons of disintermediation in the tourism industry. The primary reason is the development of technological platforms offering alternates to the traditional intermediates. The other reason is the cost reductions due to the removal of intermediates. The Internet offers a platform where tickets can not only be booked online but various tourism packages can be customized more effectively than the traditional methods. It makes the marketplace highly competitive as information available to the consumers as well as the options available to them is numerous. More destination choices, there detailed information including videos and availability of an interactive platform such as internet benefits the customer groups. The service providers are able to offer services at the lower cost as the commissions and charges involved for the intermediates are reduced.

The Structure And Function Of Proteins Biology Essay

The Structure And Function Of Proteins Biology Essay Proteins are large macromolecules which consist of hydrogen, carbon and oxygen; proteins are polymeric chains that are built from monomers known as amino acids. Proteins have a major function in a living organism, for example, the replication of DNA, catalysing metabolic reactions (catalyst); stimulus response and also transporting molecules form one place to another. There are 20 different types of amino acids which synthesize proteins, however the function and different properties of each type of protein is due to the precise sequence and structure of the amino acids present. Each amino acid consists of a central carbon atom (C), which is attached to a hydrogen atom (H), an amino group (also known as NH2 group), a carboxyl group (- COOH, this gives up a proton hence why this is known as an acid) and also a unique side chain or R group. Amino acids are linked linearly via covalent peptide bonds, short chain amino acids are known as peptides whereas long chain formations of amino acids are called polypeptides, where the peptide bond is formed between the carboxyl group of one amino acid and the amino group on the neighbouring amino acid. This reaction occurs as a condensation reaction where there is a removal of a hydrogen atom from the amino group of one amino acid and the removal of a à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬OH group from the carboxyl acid from another amino acid forming a water molecule (Fig 1). http://ibhumanbiochemistry.wikispaces.com/file/view/CondensationReaction.jpg/31781961/CondensationReaction.jpg Fig 1: a condensation reaction between two amino acid molecules, there is a formation of a water molecule as a waste product. The unique side chain or R group is what disguises one amino acid from another; the overall structure and properties of the proteins are therefore dependent on sequence of the R group of each amino acid. Furthermore these variations of the R group and also the arrangements of the other amino acids would form a number of different polypeptides. Each protein consists of a different number of these polypeptide chains which are folded into complex three dimensional shapes therefore different proteins would have different shapes. There are four levels of protein organization found in polypeptides; these structures are known as: primary structure, secondary structure, tertiary structure and also quaternary structure. Primary structures is the basic structure of the levels of organization, the primary structure is the linear arrangements/sequence found of the amino acid in the protein, and also could be thought of as the covalent linkages found in the polypeptide chain or the protein, such as a disulphide bond. The secondary structure is the areas of folding found within the protein, where there is an ordered arrangement of the amino acids in some localized regions of the polypeptide molecule; hydrogen bonds play a vital role in stabilizing the folding patterns which are found in the protein molecule. Although the conformation of each protein molecule are considered unique, there are two main types of secondary structure, or folding patterns, that are often present; these are the alpha helix and the anti-parallel beta-pleated sheets, these two folding patterns are common due to the hydrogen bonding occurs between the N-H and C=O groups in the backbone of the polypeptide. However there are a number of other secondary structures but the alpha helix and the anti-parallel sheets are the most stable form of secondary structures found. Furthermore there may be a number of these two types of secondary structure found in a single polypeptide chain. An alpha helix is spiral structure where this could be either a right handed or left handed spiral, in which the peptide bonds are found to be Trans conformational and planar, it would also be found that the amino group of each of the peptide bonds is generally in the upward position where as the carboxyl group points in the downwards position. An alpha helix structure is generated when a single polypeptide chain has turned around itself to form a rigid cylinder where a hydrogen bond is formed between every fourth amino acid (fig 1.2), which links the C=O group of one peptide bond to the N-H group on another amino acid (fig 1.2). http://faculty.ccbcmd.edu/courses/bio141/lecguide/unit3/viruses/images/alphahelix.jpg Fig 1.2: shows the hydrogen bond formed between every fourth amino acid, also linking the N-H group and O=H group. There are two types of beta sheets; parallel and anti-parallel beta sheets. The Beta pleated sheets are extended polypeptide chains with another neighbouring polypeptide chain extending either parallel or anti-parallel to each other, this occurs due to the hydrogen bonds being formed between the segments of the polypeptide chain so are essentially place side by side. The parallel beta sheets is when the structure is shown to consist a polypeptide chain and neighbouring polypeptide chain that would run in the same direction (from the N-terminus to the C-terminus), is known as the parallel beta sheet (Fig 2.1), whereas when the polypeptide chain runs in the opposite direction of that of its neighbouring chain, it is known as an anti-parallel beta sheet (Fig 2.2). http://t2.gstatic.com/images?q=tbn:ANd9GcSXEJyNbzn7F6PlFREwMGrUg4oz5Ysk1Fho12R9GMWzGFSIQjfK9M9bVZ80 Fig 2.1: shows the parallel beta sheets, the dotted line represents hydrogen bonds. The polypeptide chains shown are placed side by side but run in the same direction so are parallel to each other. Fig 2.2: shows the anti-parallel beta sheets, the dotted line represents hydrogen bonds. The polypeptide chains shown are placed side by side but run in the opposite direction so are anti-parallel to each other. The beta sheet are stable structures that produces a very rigid, pleated structure; this is due to the beta sheet being stabilized by hydrogen bond being formed between the amino group on one polypeptide chain and the carboxyl group on the adjacent chain. The tertiary structure of a protein is the full three dimensional structure of the arrangements of atoms found within the polypeptide chain, this structure is the final geometric shape that protein assume and would be the highest level structure that a protein can attain, the structures include the alpha helix, beta sheets, random coils and also other structures such as loops and folds, which are formed between the N-terminus and the C-terminus. The tertiary structure is mainly stabilized by the formation of disulphide bonds, this is also known as a disulphide bridge because these bonds are formed by oxidation reaction of the side chains of cysteine, by oxidizing the two thiol groups (SH) which would form a disulphide bond (S-S) (fig 3). http://www.elmhurst.edu/~chm/vchembook/images/563cysdisulfide.gif Fig 3: Shows the equation of an oxidation reaction in the tertiary structure to form a disulphide bridge (S-S), where a molecule of water is formed. The quaternary structure of a protein is the arrangements of many different types of coiled and folded polypeptides to form a unique functional protein and is stabilized by several non-covalent bonding, where some of these types of bonding are also found in tertiary structures, for example; hydrogen bonding, Van Der Waals interactions, hydrophobic interactions and also ionic interactions. These can occur if there is more than one polypeptide chain present in a complex protein.

Luna Pen Case Writeup

Report on Luna Pen case PA major 0420830 Lee Joo-Hyun Q1. If you were in Erika’s position, what steps might give you the best chance of achieving your goals? First of all, I think it’s rather dangerous to prepare negotiation plan solely based on stereotype of specific race/nationality. But still it’s foolish to ignore cultural difference. Since negotiation counterpart Feng is not from mainland China but from Taiwan, I believe there would be little or no disadvantage of Erika being female.But in case DGG is planning a bigger picture (for example, sharing distribution system of Global Service in Asia region) than just resolving trademark right issue, I think it is better to consider the fact Taiwanese regard Guan-Xi (relationship) as important aspect in terms of long term, friendly relationship. Therefore it would probably be a good idea to prepare a male represent with similar position to Erika along with her. Secondly Erika needs to gather more information about the counterpart; Feng and Global Service.After all, negotiation process is to find compromise or creative option between my constraint conditions/needs and their constraint conditions/needs. I’ll discuss about it more in following Question #2. Thirdly, Erika needs to build up negotiation plan. She need to determine what DGG intend to/should earn and how far DGG can back down. After defining goals & constraints (or setting Maginot Line), assuming the worst case scenario is also important step.In this case, the worst case possible could be something like this; â€Å"Feng & Global Service refuses to negotiate, pointing out that DGG abandoned and stop making product under the name of Luna. Thus DGG is left with no other choice but to file an uncertain lawsuit which would be both time consuming and costly. † To prevent this from happening, it would be unwise to start the first contact with firm stand like writing Feng that his company must cease its unauthorized use of he L una name, and that DGG is prepared to file lawsuit if necessary. Instead, I think it’s better to mention that DGG is aware of the fact that Luna pen is selling well under the marketing and distribution power of Feng and Global Service and DGG is more than willing to negotiate about the usage of Luna name. Q2. What further information might you need before contacting Feng; and how might you realistically obtain it? First of all, DGG need to figure out brand value (or brand power) of Luna by doing brief market research.By doing so, DGG can tell how much the brand power affected the total sale of Feng’s Luna pen and use it as a sharable standard in negotiation. I believe this data can be obtained rather simply. All DGG have to do is to run series of survey to group of customers, asking their willingness to pay for given pen with/without brand name Luna. Secondly, it would be a good idea to find potential buyers that are willing to buy the trademark Luna. The information o f potential buyers could later be used as a mean to pressure Feng and Global Service if necessary.Since selling Luna brand would not harm DGG, by contacting company in pen making business, DGG can obtain information of potential buyers while spreading news that DGG is trying to sell Luna name as well. And as a last resort, DGG should investigate the legal position of DGG in this case. (Especially in terms of Taiwanese court) If DGG files a lawsuit, what are the odd of winning the case, how long will it take, and how much is the estimated cost of lawsuit?The answers to these questions are key factors to decide whether to file a lawsuit or not. If odds are against DGG, it will be more reasonable to approach this negotiation in more cooperative, soft stand. On the other hand, if the odds are in favor of DGG, DGG can use lawsuit both as leverage to pressure Feng and last resort to settle this matter. Such data can be obtained via corporate legal department.

Determination of a Chemical Formula

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another, the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound, the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound.For example, if we resolved a sample of the compound NaOH weighing 40 grams into its elements, we would find that we obtained just about 23 grams of sodium, 16 grams of oxygen, and 1 gram of hydrogen. The sample of NaOH contains equal numbers of Na, O, and H atoms. Since this is the case, the atom ratio Na:O:H is 1:1:1, and so the simplest formula is NaOH. In terms of moles, we have one mole of Na, 23 grams, one mole of O, 16 grams, and one more of H, 1 gram. From this kind of argument we can conclude that the atom ra tio in a compound is equal to the mole ratio.We get the mole ratio from chemical analysis, and from that the formula of the compound. In this experiment, we will use these principles to find the formula of the compound with the general formula CuxCly zH2O, where x, y, and z are integers which establish the formula of the compound. The compound we will study is called copper chloride hydrate. We first drive out the water, which is called hydration. This occurs if we gently heat the sample to a little over 100*C. The compound formed is anhydrous (no water) copper chloride.If we subtract its mass from that hydrate, we can determine the mass of the water that was driven off, and using the molar mass of water, find the number of moles of H2O that were in the sample. Next, we need to the find either the mass of copper of chlorine in the anhydrous sample we have prepared. (It is easier to find one mass and find the other by difference. ) We do this by dissolving the anhydrous sample in wat er, which gives us a green solution. To that solution we add some aluminum metal wire, which will react to the ions, converting them to copper metal. As the reaction proceeds, copper metal will appear on the aluminum wire with typical red-orange color. When the reaction is complete, we remove the excess Al, separate the copper from the solution, and weigh the dried metal. From its mass we can calculate the number of moles of Cu in the sample. We find the mass of Cl by subtracting the mass of Cu from that of the anhydrous copper chloride, and from that value determine the number of moles of Cl. The more ratio for Cu:Cl:H2O gives us the formula of the compound. Experimental Weigh a clean, dry crucible, without a cover, accurately on the analytical balance. Place about 1 gram of the unknown hydrated copper chloride in the crucible.Then weigh the crucible and contents on the balance. Enter results on the Data page. Place the uncovered crucible on a clay triangle supported by an iron rin g. Light your Bunsen burner away from the crucible, and adjust the burner so that you have a small flame. Gentely heat the crucible as you more the burner back and forth. Do not overheat the sample. As the sample warms, the color will change from blue-green crystals to the anhydrous brown form. After all the crystals are brown, remove the burner, cover the crucible to minimize rehydration, and let cool for 15 minutes.Finally, weigh the cool uncovered crucible and contents. Transfer the brown crystals in the crucible to a 50-mL beaker. Rinse out the crucible with two 5-mL portions of distilled water, and add rinsings to the beaker. Swirl the beaker to dissolve crystals. The color will change to blue-green as the copper ions are rehydrated. Take about 20cm of 20-guage aluminum wire (~0. 25g) and form the wire into a loose spiral coil. Immerse the coil into the solution. As the copper ions are reduced, the color of the solution will fade. The reaction will take about 30 minutes to comp lete.The solution will be colorless and most of the copper metal that was produced will be on the Al wire. Add 5 drops of 6M HCl to dissolve any insoluble Al salts and clear up the solutions. Use your glass stirring rod to remove the copper from the wire. When finished, put the wire aside. In the beaker, you now have metallic copper in a solution containing aluminum salt. Next, we will use a Buchner funnel to separate the copper from the solution. Weight accurately a dry piece of filter paper that will fit the Buchner funnel, and record its mass. Put the paper on the funnel; apply light suction as you add a few mL of water to ensure a good seal.With suction on, decant the solution into the funnel. Wash the copper metal thoroughly with distilled water, then transfer the wash and all of the copper to the funnel. Rinse the copper of the paper once more and turn off suction. Add 5-mL of 95% ethanol to the funnel. After a minute or so, turn suction back on. Draw air through the funnel fo r about 5 minutes. With your spatula, lift the filter paper from the funnel. Dry the paper and copper under a heat lamp for 5 minutes. Allow it to cool to room temperature and then weigh it accurately. Results Atomic Masses:Copper (Cu)| 63. 55| Chlorine (Cl)| 35. 45| Hydrogen (H)| 1. 008| Oxygen (O)| 16. 00| Mass of crucible| 24. 374 g| Mass of crucible and hydrated sample| 24. 881 g| Mass of hydrated sample| 0. 507 g| Mass of crucible and dehydrated sample| 24. 763 g| Mass of dehydrated sample| 0. 389 g| Mass of filter paper| 0. 260 g| Mass of filter paper and copper| 0. 430 g| Mass of copper| 0. 170 g| No. mole of copper| 0. 003 moles| Mass of water evolved| 0. 118 g| No. moles of water| 0. 007 moles| Mass of chlorine in sample (by difference)| 0. 219 g| No. moles of chlorine| 0. 006 moles|Mole ratio, chlorine: copper in sample| 2:1| Mole ratio, water: copper in hydrated sample| 2:1| Formula of dehydrated sample| CuCl2| Formula of hydrated sample| CuCl2 ‘ 2H2O| Discussion Th e significance and relevance of the experimental results is that I was able to determine the chemical formula for the unknown compound, which was copper chloride hydrate. By finding out the mole ratio, I was able to find out the chemical formula. My results were precise and accurate. My results were expected, and gave me the answer CuCl2 (dehydrated sample) and CuCl2 2H2O (hydrated sample).Conclusion The experiment went as planned. During dehydration, the color changed from blue-green to brown (anhydrous), and returned back to blue-green when water was added. When the aluminum wire was added to the solution, the copper ions were reduced to the metal, and the wire was changed to a red-orange color. From the mass calculations of the samples, I was able to find the number of moles. With mole ratio of the hydrated and dehydrated, determining the chemical formula for each was easy. The conclusion is that it is possible to find the chemical formula of an unknown compound.
