Write the name of the main Constituent of Biogas also state its percentage

Answer:- Biogas is the gas that is produced by the breakdown of an organic matter by bacteria under anaerobic conditions. The biogas mainly consists of methane, carbon dioxide, and hydrogen. The other components which comprise biogas are hydrogen sulfide, oxygen, and hydrogen. The composition of the constituents of biogas in percentage are as follows:

(Carbon dioxide): 25-50%, Nitrogen: 20-10%, Hydrogen: 0-1%, Hydrogen sulfide: 0-3%, Methane: 50-75%, and Oxygen: 0-0.5%. The main constituent of biogas is Methane with a composition of 50-75%.
