1) 2Ni + O2 → 2NiO (conditions: temperature; nickel oxide; compound reaction).
2) NiO + H2SO4 → NiSO4 + H2O (nickel sulfate; exchange reaction, the reaction proceeds, since a weak electrolyte is formed in the form of water).
3) NiSO4 + Fe → FeSO4 + Ni (ferrous sulfate, nickel; substitution reaction).
4) Ni + CO2 + H2O → NiCO3 + H2 (nickel carbonate, hydrogen; substitution reaction).
5) NiCO3 → NiO + CO2 (conditions: temperature; nickel oxide, carbon dioxide (carbon (IV) oxide); decomposition reaction).
6) NiO + H2 → Ni + H2O (nickel; substitution reaction).
