Question

Gases like ______, _____, ______ and ______ are generated in a biogas plant.

• A. Methane ($C{H}_4$) , ($C{O}_2$), Hydrogen ($H_2$) and $H_{2}S$
• B. Sulphuric acid, ($C{O}_2$), Hydrogen ($H_2$) and $H_{2}S$
• C. Methane ($C{H}_4$), Oxygen, Hydrogen ($H_2$) and $H_{2}S$
• D. methane ($C{H}_4$), $C{O}_2$, Sulphuric acid and $H_{2}S$

Answer 1

Answer: (A)

Methane ($C{H}_4$) , ($C{O}_2$), Hydrogen ($H_2$) and $H_{2}S$

Biogas is an energy-rich gas produced by anaerobic decomposition or thermochemical conversion of biomass. Biogas is composed mostly of methane $\left(C{H}_4\right)$, the same compound in natural gas, and carbon dioxide $\left(C{O}_2\right)$.
