Hi chemforums, I have tried my best to solve these two questions but I am not sure of the definite answer. This is my final attempt and if I were to mess this up I would lose 1 point, which in the long run, weighs a lot.

If you can please help double check my work/let me know what answers I should select given everything, I would much appreciate it. Thank you in advance for your *delete me*
