Aluminum sulfate can be made by reacting crushed bauxite ore with sulfuric acid, according to the following chemical equation: Al2O3 + 3H₂SO4 → Al2(SO4)3 + 3H2 The bauxite ore contains 55.40% by weight of aluminum oxide, the remainder being impurities. The sulfuric acid solution contains 77.70% pure sulfuric acid and remainder water. To produce crude aluminum sulfate containing 2000 pounds of pure aluminum sulfate, 1080 pounds of bauxite and 2510 pounds of sulfuric acid solution was used. Determine the limiting and excess reactant, the percent excess of the excess reactant that was used, and degree of completion of the reaction.
