Question 3(multiple choice worth 2 points) when 3.5 mol al react with 12.5 mol hcl, what is the limiting reactant and how many moles of h2 can be formed? 2al + 6hcl yields 2alcl3 + 3h2 al is the limiting reactant, and 3.5 mol h2 can be formed hcl is the limiting reactant, and 3.2 mol h2 can be formed al is the limiting reactant, and 5.3 mol h2 can be formed hcl is the limiting reactant, and 6.3 mol h2 can be formed
