1) 3Fe + 2O2 → FeO * Fe2O3 (iron scale (mixture of iron (II) and (III) oxide); compound reaction).

2) FeO + 2HCl → FeCl2 + H2O (iron (II) chloride; exchange reaction, the reaction proceeds, since a weak electrolyte is formed in the form of water).

3) FeCl2 + 2NaOH → Fe (OH) 2 + 2NaCl (iron (II) hydroxide, sodium chloride; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of iron (II) hydroxide).

4) Fe (OH) 2 + H2SO4 → FeSO4 + 2H2O (iron (II) sulfate; exchange reaction, the reaction proceeds, since a weak electrolyte is formed in the form of water).

5) FeSO4 + 2NaOH → Fe (OH) 2 + Na2SO4 (iron (II) hydroxide, sodium sulfate; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of iron (II) hydroxide).

6) Fe (OH) 2 → FeO + H2O (conditions: temperature; iron (II) oxide; decomposition reaction).
