Answer:
Water gas is a mixture of hydrogen and carbon monoxide.
Water gas
Water gas is also known as synthesis gas or syngas. Since the mixture of the two gases is used for the synthesis of methanol, it is called syngas.
Production of water gas
Syngas is produced on the action of steam with hydrocarbons or coke at a high temperature in the presence of a catalyst.
\(\begin{array}{l}CnH_{2n+2}+nH_{2}o\rightarrow nCO+(3n+1)H_{2}\end{array} \)
Example:
\(\begin{array}{l}CH_{4(g)}+H_{2}O_{(g)}\rightarrow CO_{(g)}+3H_{2(g)}\end{array} \)
