Decomposition Reaction Definition:
A decomposition reaction occurs when a single compound separates into two or more simpler substances.
Water Electrolysis Example:
Electrolysis of water involves passing an electric current through H₂O, causing it to decompose into hydrogen (H₂) and oxygen (O₂).
H₂O → H₂ + O₂
Analysis:
- H₂O serves as the single compound.
- Electrical current initiates its breakdown into hydrogen gas (H₂) and oxygen gas (O₂).
- This process exemplifies a decomposition reaction's core principle: a single compound yielding simpler substances.
Summary:
Water electrolysis is classified as a decomposition reaction due to the breakdown of the single compound, water, into its simpler constituent elements, hydrogen and oxygen gases.
