Nitrogen → ammonia → nitric oxide (II) → nitric oxide (IV) → nitric acid → aluminum nitrate → ammonia
N2 → NH3 → NO → NO2 → HNO3 → Al (NO3) 3 → NH3
1) N2 + 3H2 → 2NH3 ↑;
2) 4NH3 ↑ + 5O2 → 4NO + 6H2O;
3) 2NO + O2 → 2NO2;
4) 4NO2 + 2H2O + O2 → 4HNO3;
5) 3HNO3 + Al (OH) 3 ↓ → 3H2O + Al (NO3) 3;
6) Al (NO3) 3 + NH4OH → Al (OH) 3 ↓ + NH4NO3;
7) NH4NO3 + NaOH → NaNO3 + NH3 + H2O.
