When 7.0 mol al react with 8.5 mol hcl, what is the limiting reactant and how many moles of alcl3 can be formed?

2 al + 6 hcl yields 2 alcl3 + 3 h2

al is the limiting reactant; 7.0 mol alcl3 can be formed
hcl is the limiting reactant; 2.8 mol alcl3 can be formed
al is the limiting reactant; 3.5 mol alcl3 can be formed
hcl is the limiting reactant; 8.5 mol alcl3 can be formed
