Question 1

Balance the following oxidation-reduction reaction in acid solution:

SO₃^2-(aq) + MnO₄^-(aq) → SO₄^2-(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)
