Bromination of Acetanilide

I need help with the first part of my orgo 2 lab.

1. Balance the following reaction equations: a) NaBr(aq)+NaClO(aq)Br2(l)+NaCl(aq)+H2O (need to balance a redox reaction!) b) CH3COOH +HB 2. Based on your above answers, and your measured amounts, what was the limiting reactant for your reaction? 3. Based on your above answer, calculate: a) the theoretical yield for the reaction b) the percent yield that you obtained
