Give me examples of chemical reaction

Here are a few examples of chemical reactions:

1. Combustion: The rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.

   • Example: Burning wood. $$\text{Wood} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{Energy}$$

2. Oxidation: A chemical reaction that involves the loss of electrons or an increase in oxidation state.

   • Example: Rusting of iron. $$4\text{Fe} + 3\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_3$$

3. Acid-Base Neutralization: A reaction between an acid and a base, forming salt and water.

   • Example: Mixing hydrochloric acid with sodium hydroxide. $$\text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H}_2\text{O}$$

4. Decomposition: A reaction where a single compound breaks down into two or more simpler substances.

   • Example: Decomposition of hydrogen peroxide. $$2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2$$
