Question

Carbon monoxide is produced by the complete burning of fuels such as coal, petrol, and diesel.

State true or false. Correct if wrong statement.

• A. True
• B. False

Answer 1

The correct option is B False

Burning of any fuel, the gas which is produced is carbon dioxide(${\mathrm{CO}}_2$) not carbon monoxide(CO).

On complete burning of fuel-

$$\begin{gathered} \mathrm{Fuel}+{\mathrm{O}}_2\to {\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O} \\ \mathrm{sufficient}\mathrm{carbon}\mathrm{dioxide} \end{gathered}$$

On incomplete burning of fuel-

$$\begin{gathered} \mathrm{Fuel}+{\mathrm{O}}_2\to \mathrm{CO}+{\mathrm{H}}_2\mathrm{O} \\ \mathrm{not}\mathrm{carbon}\mathrm{monoxide} \\ \mathrm{suffiecient} \end{gathered}$$

So, by these reactions, it is clear that if a sufficient amount of oxygen complete combustion will take place and carbon dioxide will be produced while with insufficient oxygen supply, carbon monoxide will be produced.

Hence, The given statement is False.
