Chemistry - Hydrogen and Its compound Question with Solution | TestHub

A gaseous mixture of hydrogen (H₂) and carbon monoxide (CO) is known as water gas because it is traditionally produced by passing steam over red-hot coke.

It is also called synthesis gas because it is widely used as a starting material for the commercial synthesis of methanol and various hydrocarbons.

The term syn gas is simply a universally accepted, shortened abbreviation for synthesis gas.

Since all three terms correctly describe the exact same mixture of H₂ and CO, all given options apply.
