Question

what role does stoichiometry play in finding the limiting reactant?
a. it helps in calculating the mole ratios in the balanced chemical equation
b. it identifies which reactant is a gas
c. it determines the temperature at which the reaction is most efficient
d. it measures the speed of the reaction

Explanation:

Stoichiometry is used to calculate mole - ratios from balanced chemical equations, which is crucial for finding the limiting reactant. The other options are not related to the role of stoichiometry in finding the limiting reactant.

Answer:

A. It helps in calculating the mole ratios in the balanced chemical equation
