- 1. James put the battery on the freezer. Will it prolong the batter life or not? Why? 2. What is photocatalyst and how can we prevent it? Answer 1 and 2Ochem prelab question I"ve attached part of the lab, but basically we are reducing m-nitroacetophenone to m-aminoacetophenone using granular tin. I've also attached one of my workups for the prelab, which require us to show the half reaction equation for reduction, the half reaction equation for oxidation and the overall balanced equation. Then determine the limiting reactant and theoretical yield Can you please check my work... especially my half reactions and see if those are correct (I'm not sure about the added e- and H+ Also, is the limiting reactant tin or should it be m-nitroacetophenoneHello! quick question, when a chem problem starts with "refer to the unbalanced equation below" , and theres a unbalanced equation below (lol), do i have to first balance the equation first and then solve for problem? or am i supposed to just solve assuming its a 1 for the coefficent of each reactant and product? thanks in advance!
