Question 1

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 the Fe3+ present in the ore sample. The chemical equation for the reaction is

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

◦ 16.79%
◦ 5.365%
◦ 8.396%
◦ 33.58%

Question 2

How many grams of H2 gas can be produced by the reaction of 54.0 grams of Al(s) with an excess of dilute hydrochloric acid in the reaction shown below?

2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g)

◦ 2.68 g
◦ 4.04 g
◦ 12.1 g
◦ 6.05 g
