Aluminum (Al) reacts with sulfuric acid, H2SO4, which is the acid in an automobile batties, according to the equation : 2Al + 3H2SO4 → Al2 (SO4)3 + 3H2

If 20.0 grams Al is put into a solution containing 115 g of H2SO4.

a. Which of the reactants is the limiting reagent?
b. How many grams of Al2 (So4) will be be formed?
c. How many grams of the reactant in excess will be left over?
d. How many moles of H2 will be formed?
