Question

Carbon dioxide and water are the main products of combustion.

• A. True
• B. False

Answer 1

The correct option is A True

Combustion: Combustion is an exothermic chemical reaction, in which a substance (fuel) burns with the help of oxygen to produce carbon dioxide, water vapor, heat, and light.

• Carbon dioxide, water, heat, and light are all produced during complete combustion.
• The substance which is used for burning is called combustible substances.
• The fuel substances are used for burning as they provide a large amount of energy in the form of heat (or light).
• For example, the burning of hydrocarbon (methane) completely in the presence of oxygen gives out carbon dioxide, water vapor, and energy in the form of heat, and light.
• $\underset{\mathrm{Methane}}{{\mathrm{CH}}_4}+\underset{\mathrm{Oxygen}}{2{\mathrm{O}}_2}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}}+\mathrm{Heat}$

Thus, the given statement is true.
