Question

Ammonia (NH3) breaks down into nitrogen and water by: 4NH3 + 3O2 > 2N2 + 6H2O. How many miles of water will be produced if 12 moles of ammonia decomposes?

Answer 1

Answer:

$\boxed{ \text{18 mol}}$

Explanation:

(a) Balanced equation

4NH₃ + 3O₂ ⟶ 2N₂ + 6H₂O

(b) Calculation

You want to convert moles of NH₃  to moles of H₂O

The molar ratio is 6 mol H₂O:4 mol NH₃

$\text{Moles of H _{2} O} =\text{12 mol NH _{3} } \times \dfrac{\text{6 mol H _{2} O}}{\text{4 mol NH _{3} }} = \textbf{18 mol H _{2} O}\\\\\text{The reaction will produce }\boxed{ \textbf{18 mol of H _{2} O}}$
