Yes, I know this doesn't belong in the math category. Yes, I've posted the same question 4 times due to people not giving me adequate responses. Also, 50 points. This is a two-part assignment and I can't exactly finish it due to not understanding a single thing other than the "balanced equation" part.
I already completed that, though. If you could help me with the last 2 questions, that'd be great.
First image is context.
