Here's a breakdown:
* Decomposition: The process of breaking down a compound into simpler substances.
* Reaction: A chemical process where substances change into different substances.
Examples of Decomposition Reactions:
* Electrolysis of water: Water (H₂O) is broken down into hydrogen gas (H₂) and oxygen gas (O₂) using electricity.
* Heating of calcium carbonate: Calcium carbonate (CaCO₃) decomposes into calcium oxide (CaO) and carbon dioxide (CO₂).
* Burning of wood: Wood is broken down into simpler substances like carbon dioxide (CO₂), water (H₂O), and ash.
Key Features of Decomposition Reactions:
* One reactant: A single compound is the starting material.
* Two or more products: The compound breaks down into simpler substances.
* Energy input: Decomposition reactions typically require energy input, such as heat, light, or electricity.
