Question

13. Composition of water gas is ________.

Answer 1

• Water gas is a poisonous flammable mixture that consists of Carbon monoxide $\left(\mathrm{CO}\right)$ and Hydrogen $\left({\mathrm{H}}_2\right)$ gas.
• It is usually made by blowing air and then steam over red-hot coke or coal.
• It combines with producer gas to liberate fuel gas.
• The reaction involved is:

$\underset{\mathrm{Carbon}}{\mathrm{C}}+\underset{\mathrm{Steam}}{{\mathrm{H}}_2\mathrm{O}}\to \underset{\mathrm{Water}\mathrm{gas}}{\mathrm{CO}+{\mathrm{H}}_2}$

Hence, the composition of water gas is $\mathrm{CO}+{\mathrm{H}}_2$.
