The amino acid glycine can be condensed to form a polymer called polyglycine. Draw the repeating monomer unit.

Chem 222 notes Week 13 Sample problem: Calculate ΔG for the following reaction at standard conditions: 2Ag +(aq) Cu (s)> 2Ag (s)+ Cu 2+(aq) The standard reduction potential for silver is 0.799, and the standard reduction potential for copper is 0.337. First step: figure out what you have, what you need, and what relationship gets you from what you have to what you need. You have the E for your two reactions, and 0 you need ΔG. ΔG is related to E by the following equation: ΔG=-nFE. E for the complete reaction is the sum of the E of the two half-reactions. One half reaction is going forward, and the other is going backward. In the equation at the top, silver is written as a reduction; thus, its reduction potential is the same as given in the table.
