Write the reaction equation: NH3 – N2 – NO2 – HNO3 – NO

4NH3 + 3O2 = 2N2 + 6H2O The oxidation reaction of ammonia at high temperature.

N2 + 2O2 = 2NO2 Nitrogen oxidation reaction at high temperature.

4NO2 + 2H2O + O2 = 4HNO3 This reaction is used to produce nitric acid in industry.

4HNO3 = 4NO2 + 2H2O + O2 When heated, nitric acid decomposes.
