Answer 2

Which is the component of biogas that makes it useful as fule?

• The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.

which product is formed by the combustion of elemental carbon?

• manganese oxide is used to oxidise the soot and organic compounds to carbon dioxide (CO2) and this is then mixed with hydrogen in the presence of a nickel catalyst, which converts the carbon dioxide to methane (CH4).

is biogas combustion reaction endothermic or exothermic?

• It is not an endothermic reaction. Combustion always involves the addition of O2,in combustion always energy is released and this energy is used to break the bonds of reactants. So combustion of methane is an exothermic reaction.
