Burning of LPG: Type of Combustion
Burning of LPG (liquefied petroleum gas) is a type of combustion known as "complete combustion."

Complete Combustion
- Complete combustion occurs when a fuel (in this case, LPG) reacts with oxygen (O2) in the air to produce carbon dioxide (CO2) and water (H2O) as the only products.
- LPG is a hydrocarbon fuel composed mainly of propane and butane. When LPG burns, it reacts with oxygen to release heat energy, producing carbon dioxide and water vapor.
- The chemical equation for the combustion of LPG can be represented as:
C3H8 + 5 O2 → 3 CO2 + 4 H2O

Characteristics of Complete Combustion
- In complete combustion, there is a sufficient oxygen supply for the fuel to burn completely.
- It results in a clean and efficient burning process, with minimal production of pollutants such as carbon monoxide (CO) and soot.
- The flame produced during complete combustion is blue in color, indicating a clean and efficient burning process.

Importance of Complete Combustion
- Complete combustion is important for reducing air pollution and maximizing the energy efficiency of the burning process.
- It ensures that the fuel is utilized efficiently, producing maximum heat energy with minimal waste products.
In conclusion, the burning of LPG is a type of complete combustion where the fuel reacts with oxygen to produce carbon dioxide and water as the only products. This process is clean, efficient, and essential for reducing pollution and optimizing energy use.
