Question

The composition of water gas is

• A. $\mathrm{CO}+{\mathrm{H}}_2$
• B. $\mathrm{CO}+{\mathrm{N}}_2$
• C. $\mathrm{CO}+{\mathrm{CO}}_2+{\mathrm{CH}}_4$
• D. $\mathrm{CO}+{\mathrm{CO}}_2$

Answer 1

The correct option is A

$\mathrm{CO}+{\mathrm{H}}_2$

The explanation for the correct answer:-

Option (A) $\mathrm{CO}+{\mathrm{H}}_2$

• Water gas is composed of carbon monoxide and hydrogen gas.
• It is a poisonous flammable gaseous mixture
• Made by carbon and water.
• Used as fuel and illuminant.

The explanation for the incorrect answer:-

Option (B) $\mathrm{CO}+{\mathrm{N}}_2$:

• Since water gas is a combination of carbon monoxide and hydrogen gas.
• Thus this option is incorrect.

Option (C) $\mathrm{CO}+{\mathrm{CO}}_2+{\mathrm{CH}}_4$:

• This combination is not suitable and does not approve the composition of water gas.
• This option is incorrect.

Option (D) $\mathrm{CO}+{\mathrm{CO}}_2$

• In water gas $\mathrm{CO}\mathrm{and}{\mathrm{H}}_2$ combine to form a stable complex thus, this option is incorrect.

Hence, option (A) $\mathrm{CO}+{\mathrm{H}}_2$ is correct.
