Synthesis : A + B → AB
Decomposition : AB → A + B
Single-displacement : A + CD → AD + C or A + CD → AC + D
Double-displacement : AB + CD → AD + CB
1. CuCO₃ → CuO + CO₂ (decomposition)
2. 2H₂O → 2H₂ + O₂ (decomposition)
3. C₆H₁₂ + Br₂ → C₆H₁₂Br₂ (synetheis)
4. CaCO₃ + 2HCI → CaCl₂ + H₂CO₃ (double-displacement)
5. 2Fe + 6HCl → 2FeCl₃ + 3H₂ (single-displacement)
6. O₃ → O₂ + O (decomposition)
7. Pb(NO₃)₂ + 2NaCl → 2NaNO₃ + PbCl₂ (double-displacement)
8. 8Fe + S₈ → 8FeS (synthesis)
