Here's why:
* Chemical Reactions Involve Changes in Chemical Composition: Decomposition reactions break down a single compound into two or more simpler substances. This means the chemical composition of the original compound is changing, which is the defining characteristic of a chemical reaction.
* Bonds Are Broken and Formed: In decomposition, the chemical bonds holding the compound together are broken, and new bonds may form to create the simpler products. This rearrangement of atoms and bonds is a fundamental aspect of chemical reactions.
Example:
The decomposition of water (H₂O) into hydrogen (H₂) and oxygen (O₂) is a chemical reaction:
2H₂O → 2H₂ + O₂
Key Takeaway:
Decomposition reactions are a specific type of chemical reaction where a single reactant breaks down into two or more products. They involve changes in chemical composition and bond formation/breakage, making them undeniably chemical processes.
