A combstible substance is made up of hydrocarbons (compounds containing carbon and hydrogen). When such a substance is burnt in air, carbon dioxide and water are formed, with the evolution of heat and light.
Discuss the basic characteristics difference between complete and incomplete combustion.

Explanation

### Step-by-Step Text Solution:

1. **Definition of Combustion**:
- Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light. Hydrocarbons, which are compounds made of carbon and hydrogen, undergo combustion to produce carbon dioxide (CO2) and water (H2O).

2. **Complete Combustion**:
- **Definition**: Complete combustion occurs when there is a sufficient supply of oxygen.
- **Products**: The products of complete combustion are carbon dioxide (CO2) and water (H2O).
