Write the reaction equation NH3 – NH4Cl – NH3 – NO – NO2 – HNO3

1) NH3 + HCl = NH4Cl (when ammonia reacts with hydrochloric acid, ammonium chloride is formed);

2) NH4Cl = NH3 + HCl (when ammonium chloride decomposes, ammonia and hydrochloric acid are formed);

3) 4NH3 + 5O2 = 4NO + 6H2O (when ammonia interacts with oxygen, nitrogen oxide (II) and water are formed);

4) NO + O3 = NO2 + O2 (when nitric oxide (II) interacts with ozone, nitrogen oxide (IV) and oxygen are formed);

5) 2NO2 + H2O = HNO3 + HNO2 (when nitrogen (IV) oxide interacts with water, nitric and nitrous acids are formed).
