Burning of natural gas is an example of which type of reaction?
Answer and explanation
Correct answer: Combustion reaction
Natural gas consists mainly of methane. On burning in oxygen, methane forms carbon dioxide and water and releases heat and light: \(\mathrm{CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O}\). A reaction in which a substance undergoes rapid oxidation in oxygen with release of energy is called combustion. Hence, this is a combustion reaction. In contrast, a decomposition reaction involves one compound breaking into simpler substances; here methane reacts with oxygen rather than breaking down.
