Formation of biogas from cowdung is slow, irreversible and chemical change, justify.
Answers
Answer:
yes. formation of biogas from cow dung is slow, irreversible and chemical change because biogas Can't be reversed again into cow dung. it is irreversible and chemical change. it produce methane gas.
Answer:
Biogas is formed from cow dung, raw materials, agricultural wastes, sewage, food waste etc. Biogas is produced by anaerobic organisms by digesting the material and fermenting materials. And after digestion many gases are produced. These gases react to form biogas.
Biogas ia a mixture of colourless flammable gas by the anaerobic digestion of organic waste materials. It is mainly made of methane, carbondioxide and other gases. 50% to 70% methane is present in biogas. 40 litre of dung is needed to make biogas.
Formation of biogas from cow dung is slow. Minimum of 24hour is required to produce 250g of biogas. This depends on factors such as digestion, biomass feedstock and temperature. Making of biogas from cow dung involves micro organisms digestion. They digest the cow dung by anaerobic digestion. This requires much more time.
The process of making biogas from cow dung is irreversible because biogas is made by digestion and fermentation of micro organisms. After digestion many gases are released. These gases react to form biogas. So the process is a chemical change also and it is irreversible. The reaction of gases to form biogas is irreversible.
