1) NH4Cl + NaOH → NaCl + NH3 + H2O (sodium chloride, ammonia; exchange reaction, the reaction proceeds, since gas is formed in the form of ammonia).
2) 4NH3 + 5O2 → 4NO + 6H2O (conditions: platinum, temperature; nitric oxide (II); redox reaction).
3) 2NO + O2 → 2NO2 (conditions: temperature; nitrogen oxide (IV); redox reaction).
4) 2NO2 + H2O → HNO3 + HNO2 (nitric acid, nitrous acid; redox reaction – disproportionation reaction)
5) 4HNO3 (dil.) + Cu → Cu (NO3) 2 + 2NO + 2H2O (copper (II) nitrate, nitrogen (II) oxide; redox reaction).
