Question Detail
Question
Magnesium reacts with iron(III) oxide: 3Mg + Fe₂O₃ → 3MgO + 2Fe. If 1.00 mol Mg reacts with 0.252 mol Fe₂O₃, which is limiting?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Required magnesium for 0.252 mol Fe₂O₃ is 0.756 mol, less than available Mg, so Fe₂O₃ is limiting.
Hint
Use mole ratio from balanced equation.
