Question

The gas produced by decaying agricultural waste, plant residues, animal dung etc. in the absence of air, is called-
A. Carbon dioxide
B. Biogas
C. Nitrogen
D. Ozone gas

Answer 1

Hint: The combination of gases produced via a means of the breakdown of nature depending on the absence of oxygen (anaerobically), usually together with methane and carbon dioxide. As it is a very dangerous gas. Also, it has various harmful effects.

Complete Answer:
The fuel line produced via a means of decaying agricultural waste, plant residues, animal dung, etc. with the absence of air, is referred to as Biogas. Biogas is produced via means of anaerobic digestion with methanogen or anaerobic organisms, which digest cloth interior a closed system, or fermentation of biodegradable substances.
Biogas may be compressed after elimination of Carbon dioxide, the identical manner as herbal fuel line is compressed to CNG, and used to strengthen motor vehicles. Biogas may be wiped clean and upgraded to herbal fuel line standards, while it will become bio-methane.
Biogas is taken into consideration to be a renewable aid due to the fact its manufacturing-and-use cycle is continuous, and it generates no internet carbon dioxide. Biogas can talk to fuel lines produced clearly or industrially.
Dangers of biogas-
The air pollutants produced via means of biogas are much like that of herbal fuel lines. The content material of poisonous hydrogen sulfide offers extra dangers and has been liable for critical accidents. Biogas may be explosive while combined with the ratio of 1 component biogas to 8–20 components air.
Special protection precautions should be taken for getting into an empty biogas digester for upkeep work. If biogas is smelled everywhere home windows and doorways need to be opened immediately. If there may be a hearth place the fuel line needs to be close off on the gate valve of the biogas system.
Biogas is the combination of gases produced via a means of the breakdown of nature depending on the absence of oxygen. Biogas may be made out of uncooked substances consisting of agricultural waste, manure, municipal waste, plant cloth, sewage, inexperienced waste, or meal waste. Biogas is a renewable strength source.
So, the correct answer is Option C.


Note: the Biogas manufacturing is offering in recent times new possibilities for professional employment, drawing on the improvement of latest technologies. Biogas in India has been historically primarily based totally on dairy manure as feed inventory and these "gobar" fuel.
