Explain? a) Cys-Arg-Ala-Gly-Asn-Arg-Lys-Ile-Leu-Glu-Thr-Tyr b) Ser-Glu-Asp-Asn-Phe-Gly-Ala-Pro-Lys-Ser-Ille-Leu-Trp c) Gln-Lys-Ala-Ser-Val-Glu-Met-Ala-Val-Arg-Asn-Ser-Gly- 3) What is the pH of a 1L solution of 0.35 M acetic acid(ka acetic acid= 1.74x10^-3) pKa of acetic acid_ 4.76? Also if you accidentally spilled 50ml of water into this solution, what would the pH be? 4) which has the greater entropy a polymeric molecule or a mixture of its constituent monomers? explain? 5) which of the following are never spontaneous?
