Problem

You may want to reference (Pages 850 - 851)Section 20.1 while completing this problem.

For each of the following balanced oxidation-reduction reactions, (i) identify the oxidation numbers for all the elements in the reactants and products and (ii) state the total number of electrons transferred in each reaction.

(a) 2 MnO4-(aq) + 3 S2-(aq) + 4 H2O(l) → 3 S(s) + 2MnO2(s) + 8 OH-(aq)
