The biogas used for cooking is a mixture of which of the following?

1. Carbon dioxide and oxygen
2. Isobutane and propane
3. Methane and carbon monoxide
4. Methane and carbon dioxide

Correct Option: D

Biogas is essentially a mixture of Methane (CH₄, around 55-75%) but also contains Carbon Dioxide (CO₂), around 25-30%), varying quantities of Water (H₂O) and Hydrogen Sulphide (H₂S). Other compounds can also be found, especially in waste dump biogas: Ammonia (NH<3), Hydrogen (H₂), Nitrogen (N₂) and Carbon Monoxide (CO). Methane is the valuable component under the aspect of using biogas fuel.
