Here's a breakdown:
* Decomposition reactions are chemical reactions where a single reactant breaks down into two or more products.
* This process typically requires energy input, often in the form of heat, light, or electricity.
* The opposite of decomposition is synthesis, where two or more reactants combine to form a single product.
Examples of Decomposition Reactions:
* Electrolysis of water: Water (H₂O) is broken down into hydrogen gas (H₂) and oxygen gas (O₂) by passing an electric current through it.
* Thermal decomposition of limestone: Calcium carbonate (CaCO₃) breaks down into calcium oxide (CaO) and carbon dioxide (CO₂) when heated.
* Photosynthesis: Plants use sunlight to decompose carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen (O₂).
Decomposition reactions are essential in many biological and industrial processes. They are used to produce a wide range of products, from fuels to pharmaceuticals.
