Question

what determines the effect of a limiting reagent on the mass of a product?
a. the reactivity of the limiting reagent
b. the amount of the limiting reagent
c. the coefficient of the limiting reagent
d. the molar mass of the limiting reagent

Explanation:

The limiting reagent is the reactant that gets consumed first in a chemical reaction, thus determining the maximum amount of product that can be formed. The amount of the limiting reagent directly influences the mass of the product based on the stoichiometry of the reaction. Reactivity affects reaction rate but not the final mass of product determined by the limiting - reagent. The coefficient is part of the stoichiometric ratio but the actual amount (moles) of the limiting reagent matters more. Molar mass is used in calculations but the key factor is the amount of the limiting reagent available for reaction.

Answer:

B. The amount of the limiting reagent
