Reaction types.

Definition

Reaction types classify chemical reactions based on how atoms rearrange. The five main types are synthesis (combination), decomposition, single replacement, double replacement, and combustion.

Examples

Real-world.

  • 1 Synthesis: 2H₂ + O₂ → 2H₂O
  • 2 Decomposition: 2H₂O₂ → 2H₂O + O₂
  • 3 Combustion: CH₄ + 2O₂ → CO₂ + 2H₂O
