1) 2FeO → 2Fe + O2 (decomposition reaction; iron (II) oxide, iron, oxygen);
2) Fe + Cl2 → FeCl2 (compound reaction; iron, chlorine, iron (II) chloride);
3) FeCl2 + 2KOH → Fe (OH) 2 ↓ + 2KCl (exchange reaction; iron (II) chloride, potassium hydroxide, ferum (II) hydroxide, potassium chloride);
4) Fe (OH) 2 ↓ + H2SO4 → FeSO4 ↓ + 2H2O (exchange reaction; ferum (II) hydroxide, sulfuric acid, ferum (II) sulfate, water).
