Question

When 5.0 mol Al react with 13 mol HCl, what is the limiting reactant, and how many moles of AlCl3 can be formed?

2 Al + 6HCl → 2 AlCl3 + 3 H2

Answer 1

HCI is the limiting reactant, 4.3 mol AIC13 can be formed

Answer 2

Remember that these are the steps for solving a balanced chemical equation using the process of stoichiometry. The question has the given of 5.0 mols of Al that should be your starting point.
