Step 1: Understanding the Concept:
Water gas is an important industrial fuel gas consisting of a mixture of carbon monoxide and hydrogen. Step 2: Detailed Explanation:
It is produced by passing steam over red-hot carbon (coke) at high temperatures (approx 1270 K).
The reaction is:
\[ \text{C(s)} + \text{H}_2\text{O(g)} \to \text{CO(g)} + \text{H}_2\text{(g)} \]
The resulting mixture of Carbon Monoxide (\(\text{CO}\)) and Hydrogen (\(\text{H}_2\)) is called Water gas.
It is also known as synthesis gas or "syngas" because it is used in the synthesis of methanol and many hydrocarbons. Step 3: Final Answer:
The mixture of \(\text{CO}\) and \(\text{H}_2\) represents water gas.
