Write the reaction equations: Nitrogen – Ammonia – Ammonium sulfate – Ammonia – Nitrogen – Nitric oxide (II)

Nitrogen → Ammonia → Ammonium sulfate → Ammonia → Nitrogen → Nitric oxide (II)

N2 → NH3 → (NH4) 2SO4 → NH3 → N2 → NO

1) N2 + 3H2 → 2NH3 (compound reaction);

2) 2NH3 + H2SO4 → (NH4) 2SO4 (compound reaction);

3) (NH4) 2SO4 → 2NH3 + H2SO4 (decomposition reaction);

4) 4NH3 + 3O2 → 2N2 + 6H2O (substitution reaction);

5) N2 + O2 → NO (compound reaction).
