Question

$\mathrm{CO}+{\mathrm{H}}_2$ is known as

• A. Producer gas
• B. Water gas
• C. Dry ice
• D. Syn gas

Answer 1

The correct option is B

Water gas

Explanation for the correct option

(B) Water gas-

The mixture of $\mathrm{CO}+{\mathrm{H}}_2$ is known as water gas.

Water gas is formed by passing steam over red hot coke and a mixture of carbon monoxide$\left(\mathrm{CO}\right)$and hydrogen$\left(\mathrm{H}\right)$ is formed.

$\mathrm{C}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\stackrel{473-1273\mathrm{K}}{\to }\underset{\mathrm{water}\mathrm{gas}}{\mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)}$

Explanation for incorrect options:

(A) Producer gas- The mixture containing carbon monoxide, nitrogen, and hydrogen$(\mathrm{CO}+{\mathrm{N}}_2)$is known as producer gas.

(C) Dry ice- Solid carbon dioxide is known as dry ice.

(D) Syn gas- It is a mixture of Carbon monoxide, carbon dioxide and hydrogen known as syn gas$({\mathrm{CO}}_2+\mathrm{CO}+{\mathrm{H}}_2)$

Hence, option (B) is the correct answer. $\mathrm{CO}+{\mathrm{H}}_2$ is known as water gas.
