- Consider the following statement. “To produceone molecule of each possible kind of polypeptide chain,300 amino acids in length, would require more atoms thanexist in the universe.” Given the size of the universe, do yousuppose this statement could possibly be correct? Sincecounting atoms is a tricky business, consider the problemfrom the standpoint of mass. The mass of the observableuniverse is estimated to be about 1080 grams, give or takean order of magnitude or so. Assuming that the averagemass of an amino acid is 110 daltons, what would be themass of one molecule of each possible kind of polypeptidechain 300 amino acids in length? Is this greater than themass of the universe?2. In designing an experiment, the researcher can often choose many different levels of the various factors in order to try to find the best combination at which to operate. As an illustration, suppose the researcher is studying a certain chemical reaction and can choose four levels of temperature, five different pressures, and two different catalysts. (a) To consider all possible combinations, how many experiments would need to be con- ducted? (b) Often in preliminary experimentation, each factor is restricted to two levels. With the three factors noted, how many experiments would need to be run to cover all possible combinations with each of the three factors at two levels? (Note: This is often called a 23 design.)a) Often, we want to think about entropy as the sum of the entropy of an organism and itssurroundings. Write a version of the second law including these two entropies. b. How does this help you understand how an organism can become more ordered andstill obey the 2nd law? c. Name some spontaneous processes that increase the entropy of the surroundings whileincreasing the order in an organism.

Concentration of a Solution A biologist is trying to find the optimal salt concentration for the growth of a certain species of mollusk. She begins with a brine solution that has 4 g/L of salt and increases the concentration by 10% every day. Let Co denote the initial concentration, and let C, be the concen- tration after n days. (a) Find a recursive definition of C. (b) Find the salt concentration after 8 days.

At the CFA, we use our chemistry expertise and understanding to help solve problems of a potentially criminal nature. Bucks McGee, after being poisoned, is currently being treated in the hospital with an antidote- the chemical Fe7(CN)18. The compound is so intensely coloured that even a small amount of it makes for a black or dark blue suspension. Given that this antidote has never been administered at the hospital, none of the doctors or nurses have experience with it. There is one very old bottle of Fe7(CN)18 pills in the medicine storeroom, but the label is worn, and the units are in the old, archaic British Apothecaries' system which has unusual units like drachms, scruples, grains, and mites: 453.6 grams (g) = 1 pound (lb) = 12 ounces (3) = 96 drachms (3) = 288 scruples (3) = 5760 grains (gr) = 115200 mites (m) It would take days (at least!) for a new bottle of the antidote to be ordered and received, and Bucks McGee probably doesn't have…Edu properties of matter? W hat words would vou use to describe a table? A chair? A piece of cloth? You would probably say something about the shape, color, and size of each object. Next, you might consider whether the object is hard or soft, smooth or rough. Normally, when describing an object, you identify what it is about that object that you can observe without changing its identity. What are physical They Are Used to Describe a Substance A characteristic of a substance that can be observed and measured without changing the identity of the substance is called a physical property. Gold is one metal prized for its physical properties. Gold can be bent and shaped easily and has a lasting shine. Both properties make it an excellent metal for making coins and jewelry. All of your senses can be used to detect physical properties. Color, shape, size, and texture are a few of the physical properties you encounter. Think of how you would describe an object to a friend. Most likely, your…
