Synthesis gas is a mixture of

B. CH4 and H2

C. CO2 and H2

D. CO and H2

The correct answer is:

D. CO and H₂ ✅

Explanation:

• Synthesis gas (syngas) is a mixture of carbon monoxide (CO) and hydrogen (H₂).

• It is produced by gasification of coal, natural gas, or biomass and is mainly used as a feedstock for producing ammonia, methanol, and synthetic fuels.

Other options:

• A. CH₄ and H₂O → Reactants in producing syngas, not syngas itself.

• B. CH₄ and H₂ → Incorrect composition.

• C. CO₂ and H₂ → Sometimes called "reformed gas," but not classical syngas.
