Question

$CO+H_2$ is known as:

• A. water gas
• B. syn gas
• C. producer gas
• D. semi water gas

Answer 1

The correct option is A water gas

The mixture of carbon monoxide $\left(CO\right)$ and hydrogen $\left(H_2\right)$ is called water gas.

Syn gas is a mixture of $CO,C{O}_2$ and $H_2$.

Producer gas is a mixture of flammable gases (principally carbon monoxide and hydrogen) and nonflammable gases (mainly nitrogen and carbon dioxide).

Semi-water gas is a mixture of water gas and producer gas made by passing a mixture of air and steam through heated coke.

Hence, option A is correct.
