Aprotein biochemist attempted to determine the amino acid sequence of a decapeptide. use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide. trypsin digestion gave two fragments with the following residues (not in order): t1: ala, arg, phe, pro, thr, trp, tyr t2: lys, met, val chymotrypsin digestion gave three fragments with the following residues (not in order): ct1: ala, arg, phe, pro ct2: thr, trp ct3: lys, met, tyr, val n‑terminal analysis of the ct1 tetrapeptide indicated that the n‑terminal amino acid was ala. the cyanogen bromide gave only one single amino acid, methionine, and a nonapeptide. what is a possible sequence of the decapeptide? use three‑letter abbreviations in your answer, and add a dash between each residue. sequence:

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
