- Synthesis Reactions: Two or more substances react to produce a single product, like when two elements react.
- Combustion Reactions: Oxygen combines with a substance and releases heat and light.
- Decomposition Reactions: A compound breaks down into two or more elements or new compounds, often requiring an energy source.
- Replacement Reactions: Atoms of one element replace atoms of another similar element in a compound, like iron replacing copper in copper sulfate.
- Double Replacement Reactions: Ions exchange between two compounds, with cations and anions switching with each other.
This classification helps understand different types of chemical reactions, providing a framework for further study.
