Which of the following mixtures is water gas?

Which of the following mixtures is water gas?

Options

  1. ACO2(g)+H2(g)\text{CO}_{2(g)} + \text{H}_{2(g)}
  2. BCO(g)+H2(g)\text{CO}_{(g)} + \text{H}_{2(g)}
  3. CCO2(g)+N2(g)\text{CO}_{2(g)} + \text{N}_{2(g)}
  4. DSO2(g)+N2(g)\text{SO}_{2(g)} + \text{N}_{2(g)}

Correct answer

B. CO(g)+H2(g)\text{CO}_{(g)} + \text{H}_{2(g)}

Step-by-step solution

Water gas is a mixture of carbon monoxide and hydrogen gas.

It is prepared by passing steam over red-hot coke at high temperatures.

C(s)+H2O(g)→CO(g)+H2(g)\text{C}_{(s)} + \text{H}_2\text{O}_{(g)} \rightarrow \text{CO}_{(g)} + \text{H}_{2(g)}

Therefore, the mixture CO(g)+H2(g)\text{CO}_{(g)} + \text{H}_{2(g)} is known as water gas.

Answer: CO(g)+H2(g)\text{CO}_{(g)} + \text{H}_{2(g)}
