Ammonia reacts with diatomic oxygen to form nitric oxide and water vapor:
4NH₃ + 5O₂ $\rarr$ 4NO + 6H₂O
When 40.0 g NH₃ and 50.0 g O₂ are allowed to react, the limiting reagent is O₂.

Question

Ammonia reacts with diatomic oxygen to form nitric oxide and water vapor: 4NH₃ + 5O₂ $\rarr$ 4NO + 6H₂O When 40.0 g NH₃ and 50.0 g O₂ are allowed to react, the limiting reagent is O₂.

Quizplus · Accepted Answer

The limiting reagent is the reactant that is completely consumed in a reaction, limiting the amount of product that can be formed. In this case, O2 is the limiting reagent because it is completely consumed in the reaction, while NH3 is not.
