Question 1

Balance the following oxidation-reduction reaction in acid solution:

SO32-(aq) + MnO4-(aq) → SO42-(aq) + Mn2+(aq) + H2O(l)

The sum of the coefficients is ________.
◦ 23
◦ 30
◦ 13
◦ 45
◦ 28

Question 2

Based on the balanced chemical equation shown below, determine the mass percent of Fe3+ in a sample of iron ore if 22.40 mL of a 0.1000 mol L-1 stannous chloride, SnCl2(aq), solution is required to completely react with theFe3+ present in the ore sample. The chemical equation for the reaction is

2 Fe3+(aq) + Sn2+(aq) → 2 Fe2+(aq) + Sn4+(aq)

◦ 5.365%
◦ 8.396%
