Here's a breakdown:
* Decomposition: The process of breaking down a compound into simpler substances.
* Reaction: A process that involves the rearrangement of atoms and molecules.
Example:
The decomposition of water (H₂O) into hydrogen (H₂) and oxygen (O₂) is a classic example:
* 2H₂O → 2H₂ + O₂
This equation shows that two molecules of water are broken down into two molecules of hydrogen and one molecule of oxygen.
Other types of decomposition reactions:
* Thermal decomposition: Breaking down molecules by applying heat.
* Electrolysis: Breaking down molecules using electricity.
* Photolysis: Breaking down molecules using light.
Important note: Decomposition reactions are the opposite of synthesis reactions, where simpler substances combine to form a more complex one.
