Which one of the following is known as 'water gas'?

Options

  1. AH₂O + CO₂
  2. BNH₃
  3. CH₂ + N₂
  4. DCO + H₂

Correct answer

D. CO + H₂

Step-by-step solution

Water gas is a mixture of carbon monoxide ( CO ) and hydrogen gas ( H₂ ). It is produced by passing steam over red-hot coke at high temperatures: C(s) + H₂O(g) CO(g) + H₂(g) This mixture is also known as synthesis gas or syngas. Answer: CO + H₂
