Br 0 N H Assign oxidation numbers to each of the elements in the reaction below. Then compare how the oxidation numbers changed during the reaction to determine which element was oxidized and which was reduced 4BrO3(aq) + 6NH(g) 4 Br (aq) + 6N2(g) + 3H2O(1) Reactants Products Which element is oxidized? Which element is reduced? A concentration cell is constructed such that the anode consists of a copper (Cu) electrode immersed in a 1.00x103 M solution of Cu2+(aq) while the cathode has a copper (Cu) electrode immersed in a 2.00 M solution of Cu2+ (aq). Cu2+ (aq) + 2e- Cu(s) Ered +0.34V a. Write the half reactions for the anode and cathode b. Write the overall reaction c. Determine the E cell for this reaction under these conditions
