Make up the reaction equation: N2- NH3- NH4NO3- NH3- N2O – O2

1) N2 + 3H2 = 2NH3 (when nitrogen interacts with hydrogen, ammonia is formed);

2) NH3 + HNO3 = NH4NO3 (when ammonia reacts with nitric acid, ammonium nitrate is formed);

3) NH4NO3 + 4H2 = 2NH3 + 3H2O (when ammonium nitrate interacts with hydrogen, ammonia and water are formed);

4) It is impossible to obtain N2O from NH3. You can write like this:

NH3 + O2 = NO2 + H2O (when ammonia interacts with oxygen, nitrogen oxide (IV) and water are formed);

5) Then oxygen can be obtained from nitric oxide (IV):

2NO2 + O3 = O2 + N2O5 (when nitric oxide (IV) interacts with ozone, oxygen and nitrogen oxide (V) are formed).
