Question

For the balanced chemical reaction: 4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(ℓ), how many moles of H2O are produced when 0.669 mol of NH3 react?

Answer 1

The balanced chemical equation shows that for every 2 moles of NH3, 3 moles of H2O are produced. Therefore, when 0.669 mol of NH3 reacts, 1.00 mol of H2O is produced.

Step-by-step explanation:

The balanced chemical equation shows that 4 moles of NH3 react with 6 moles of H2O. This means that the mole ratio of NH3 to H2O is 4:6, which simplifies to 2:3. Therefore, for every 2 moles of NH3, 3 moles of H2O are produced.

Given that 0.669 mol of NH3 reacts, we can use the mole ratio to find the number of moles of H2O produced:

(0.669 mol NH3) * (3 mol H2O / 2 mol NH3) = 1.00 mol H2O
