Explain why soot is produced during incomplete combustion.

Explanation

**Step-by-Step Solution:**

1. **Understanding Combustion**: Combustion is a chemical reaction that occurs when a substance (usually a fuel) reacts with oxygen to produce heat and light. It can be complete or incomplete.

2. **Complete Combustion**: In complete combustion, there is a sufficient supply of oxygen. The products of complete combustion are typically carbon dioxide (CO2) and water (H2O). For example, when methane (CH4) burns completely, it produces CO2 and H2O.

3. **Incomplete Combustion**: In contrast, incomplete combustion occurs when there is a limited supply of oxygen. This means that the fuel does not fully react with oxygen.
