Give the example of Exothermic reaction

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Exothermic Reaction**:
An exothermic reaction is a type of chemical reaction that releases heat energy into the surroundings. This means that the products of the reaction have lower energy than the reactants.

2. **Example 1 - Combustion of Carbon**:
One common example of an exothermic reaction is the combustion of carbon. When carbon (C) burns in the presence of oxygen (O₂), it reacts to form carbon dioxide (CO₂). The chemical equation for this reaction is:
\[
