Here's a general representation:
AB → A + B
Where:
* AB represents the compound
* A and B represent the separate substances formed
Examples of Decomposition Reactions:
* Electrolysis of water: 2H₂O → 2H₂ + O₂
* Heating calcium carbonate: CaCO₃ → CaO + CO₂
* Decomposition of hydrogen peroxide: 2H₂O₂ → 2H₂O + O₂
Key Features of Decomposition Reactions:
* A single reactant breaks down into two or more products.
* Energy is usually required to break the bonds within the compound (e.g., heat, electricity, or light).
* The products are simpler than the reactant.
