Here's the general form of a decomposition reaction:
AB → A + B
Where:
* AB represents a compound
* A and B represent simpler products
Examples of Decomposition Reactions:
* Electrolysis of water:
* 2H₂O (l) → 2H₂ (g) + O₂ (g)
* Decomposition of calcium carbonate:
* CaCO₃ (s) → CaO (s) + CO₂ (g)
* Decomposition of hydrogen peroxide:
* 2H₂O₂ (aq) → 2H₂O (l) + O₂ (g)
Key Features of Decomposition Reactions:
* Requires energy input: Decomposition reactions usually need energy (heat, light, electricity) to occur.
* Breakdown of complex molecules: They break down large, complex molecules into smaller, simpler molecules.
* Formation of new substances: The products formed are different from the original compound.
