    This is a limiting reagent problem. How do I know that? Because BOTH reactants are given. Basically, you work one of these problems by solving two simple stoichiometry problems in one; that is, you determine the product with one of the reactants (ignore the other one), then switch reactants and ignore the other one. The answers you get for the product are different and the smaller one is ALWAYS the correct answer. Here is how you do the simple stoichiometry problem. Just follow the steps.
