Below is a table summarizing the type of reaction and the balanced chemical equation.
Reaction Type of reaction Balanced chemical equation
- HBr + Fe Single replacement reaction 2HBr + Fe → FeBr2 + H2
- K(MnO⁴) + ZnCl² Oxidation-reduction reaction K₂MnO₄ + ZnCl² → KCl + MnCl² + MnO₂ + H₂O
- MnO₂ + Sn(OH)₄ Disproportionation reaction 2MnO₂ + Sn(OH)₄ → Mn₂O₃ + SnO₂ + 4H₂O
- O₂ + C₅H₁₂O₂ Combustion reaction 2C₅H₁₂O₂ + 16O₂ → 10CO₂ + 12H₂O
- Ca(OH)₂ + HF Neutralization reaction Ca(OH)₂ + 2HF → CaF₂ + 2H₂O
- Pb(NO₃)₂ + K₂CrO₄ Precipitation reaction Pb(NO₃)₂ + K₂CrO₄ → PbCrO₄ + 2KNO₃
- NaC₂H₃O₂ + H₂SO₄ Acid-base reaction NaC₂H₃O₂ + H₂SO₄ → NaHSO₄ + C₂H₃O₂
- Cu(OH)₂ + H₃PO₄ Acid-base reaction Cu(OH)₂ + 2H₃PO₄ → Cu₃(PO₄)₂ + 6H₂O
- AgNO₃ + Na₂CO₃ Precipitation reaction AgNO₃ + Na₂CO₃ → Ag₂CO₃ + 2NaNO₃
In a single replacement reaction, one element replaces another element in a compound. In the reaction between HBr and Fe, HBr replaces H in Fe to form FeBr₂ and H₂.
An oxidation-reduction reaction, also known as a redox reaction, involves the transfer of electrons between two substances. In the reaction between K(MnO4) and ZnCl₂, K(MnO₄) is reduced to MnO₂, and Zn is oxidized to Zn₂₊.
Lastly, a disproportionation reaction is an oxidation-reduction reaction in which an element simultaneously undergoes both oxidation and reduction. In the reaction between MnO₂ and Sn(OH)₄,
