- A. Consumed reactant
- B. Limiting reactant
- C. Excess reactant
- D. Non-reacted reactant
Explanation
The limiting reactant is the reactant that is consumed first in a chemical reaction, thereby limiting the amount of product that can be formed. It is the reactant that is present in the smallest stoichiometric amount, relative to the other reactants.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
