Your question: What is the main constituent of biogas Mcq?

Biogas comprises primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes.

Which is the main constituent of biogas?

Biogas is usually made up of around 50-70% methane (CH4) and 25-45% carbon dioxide (CO2), with other gases such as hydrogen (H2), hydrogen sulphide (H2S), water vapor (H2O), nitrogen (N2), oxygen (O2), ammonia (NH3) making up the rest.

What are the two main constituents of biogas?

Biogas is primarily methane (CH4​) and carbon dioxide (CO2​) and may have small amounts of hydrogen sulphide (H2​S), moisture and siloxanes.

What is the main constituent of biogas and kitchen gas LPG?

The main constituent of biogas is methane and the main constituent of kitchen gas (LPG) is butane.

Which of the following is a main component of biogas a hydrogen B methane C hydrogen sulphide D oxygen?

Biogas is a mixture of gases, like methane, carbon dioxide, hydrogen and hydrogen sulphide which is produced by the anaerobic degradation of biomass (animal and plant wastes) in the presence of water but in the absence of oxygen. The major component of biogas is methane, as it contains up to 75% methane gas.

IMPORTANT TO KNOW:  How much propane is in a 30 pound tank?

What is the formula of biogas?

The chemical composition of biogas is as follows: 50–85% CH4 (methane); 20–35% CO2; H2, N2 and H2S form the rest (Pastorek et al. 2004).

Which gas is found maximum in biogas?

What is the composition of the biogas Toppr?

Biogas contains principally methane (CH4) and carbon dioxide (CO2) and may have little measures of hydrogen sulfide (H2S), dampness and siloxanes.

What is the main constituent of LPG?

LPG is composed hydrocarbons containing three or four carbon atoms. The normal components of LPG thus, are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present. LPG burns readily in air and has an energy content similar to petrol and twice the heat energy of natural gas.

Which gas is the main constituent of air?

Below a height of about 86 kilometers, the three main gaseous elements, which together account for about 99.9% of the total atmosphere, exist in essentially constant proportion to the total: nitrogen comprises 78% of air by volume, oxygen comprises 21% of air by volume, and argon comprises another 0.9%.

What is main constituent of acid?
