In the industrial synthesis of nitric acid, ammonia (NH3\text{NH}_3NH3​) is catalytically oxidised by oxygen gas (O2\text{O}_2O2​). During a test run of this process under specific conditions, 0.080 mol of NH3\text{NH}_3NH3​ reacts completely with exactly 0.100 mol of O2\text{O}_2O2​.

Which of the following is the correct balanced equation for this reaction?

A

4NH3+3O2→2N2+6H2O4\text{NH}_3 + 3\text{O}_2 \rightarrow 2\text{N}_2 + 6\text{H}_2\text{O}4NH3​+3O2​→2N2​+6H2​O

B

4NH3+7O2→4NO2+6H2O4\text{NH}_3 + 7\text{O}_2 \rightarrow 4\text{NO}_2 + 6\text{H}_2\text{O}4NH3​+7O2​→4NO2​+6H2​O

C

4NH3+5O2→4NO+6H2O4\text{NH}_3 + 5\text{O}_2 \rightarrow 4\text{NO} + 6\text{H}_2\text{O}4NH3​+5O2​→4NO+6H2​O

D

2NH3+2O2→N2O+3H2O2\text{NH}_3 + 2\text{O}_2 \rightarrow \text{N}_2\text{O} + 3\text{H}_2\text{O}2NH3​+2O2​→N2​O+3H2​O
