Question

Explain the process of combustion and write chemical equations of two examples of it.

Hint:

Combustion reactions are widely used in engines, cooking, and electricity generation.

Answer 1

Combustion is a chemical process in which a substance reacts with oxygen to release energy in the form of heat and light. It is an exothermic reaction that produces carbon dioxide and water in the case of hydrocarbon combustion.
Example 1: Combustion of Methane (CH4): \[ CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O + \text{Energy} \] Example 2: Combustion of Carbon (C): \[ C + O_2 \rightarrow CO_2 + \text{Energy} \]
