Question:

When asked to find the amount of yield of a specific product, when must you consider if the problem involves a limiting reactant?

Answer:

Limiting reactions must be considered in problems where amounts (mass, moles, volume+molarity) of both reactants are given. In problems that do not involve a limiting reaction, the wording of the problem will often denote which reactant is in excess.
