This is not really a question but, I have a presentation to do on one of the following polymers. I was just wondering if you can pick the top 5 best out of them all. I will include the questions I will be researching, I just want an expert opinion on which polymer would be th best for these questions. :) These are the questions that I will be resaerching about: List its current uses and why we use it for those applications. What is it? What are its components (i.e., its monomers)? How is the polymer manufactured? What is the chemical reaction that occurs in its creation? What is the chemical reaction that occurs in its degradation? What are the environmental consequences of its production? What are the environmental consequences of its disposal? Propose a solution to the environmental consequences you listed above. For example, could something about the polymer be changed to alleviate the problems or could another, safer polymer be used in its place? And these are the polymers I…
The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had 300.g of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.
