Read the statement carefully and choose the correct question.
Correct answer: A. Mg
- A. Mg
- B. HCI
- C. Both are in stoichiometric amounts
- D. MgCl2
Explanation
If equal masses of reactants are given then the reactant whose larger molar mass is used in balance chemical equation is limiting reactant so Mg will be in excess.

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.
