Composition of water gas is ……………..

Explanation

To determine the composition of water gas, we can follow these steps:

### Step 1: Understand what water gas is
Water gas is a mixture of gases that is produced when steam reacts with carbon at high temperatures.

**Hint:** Think about the process involved in making water gas and the materials used.

### Step 2: Identify the components of water gas
Water gas primarily consists of two gases: carbon monoxide (CO) and hydrogen (H2).

**Hint:** Recall the chemical symbols for carbon monoxide and hydrogen.

### Step 3: Describe the reaction that produces water gas
The reaction that produces water gas occurs when steam (H2O) is passed over red-hot coke (carbon). This reaction can be summarized as follows:
\[ \text{C (s)} + \text{H2O (g)} \rightarrow \text{CO (g)} + \text{H2 (g)} \]

**Hint:** Consider what happens to the steam and carbon when they are heated together.

### Step 4: State the composition of water gas
The composition of water gas is therefore a mixture of carbon monoxide and hydrogen. Specifically, it can be represented as:
\[ \text{Water gas} = \text{CO} + \text{H2} \]

**Hint:** Remember that water gas is also known as synthetic gas.

### Final Answer
The composition of water gas is CO (carbon monoxide) and H2 (hydrogen).
