QUESTION 1. Consider the reaction . MnO2 + 4 HCl → MnCl2 + Cl2 + 2H2O
If 0.86 mole of MnO2 and 48.2 g of HCl react, which reagent will be used up first? How many
grams of Cl2 will be produced?

QUESTION 2 .Titanium(VI) oxide (TiO2) is a white substance produced by the action of sulfuric acid on the
mineral ilmenite (FeTiO3):
FeTiO3 + H2SO4 → TiO2 + FeSO4 + H2O
Its opaque and nontoxic properties make it suitable as a pigment in plastics and paints. In one
process, 8.00 x 103 kg of FeTiO3 yielded 3.67 x 103 kg of TiO2. What is the percent yield of the
reaction?
