The reaction of solid calcium carbide with water produces ………….., a flammable gas.

Answer

To solve the question regarding the reaction of solid calcium carbide with water that produces a flammable gas, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
The reactants in this reaction are solid calcium carbide (CaC2) and water (H2O).

2. **Write the Chemical Equation**:
The reaction can be represented by the following balanced chemical equation:
\[ \text{CaC}_2 (s) + 2 \text{H}_2\text{O} (l) \rightarrow \text{C}_2\text{H}_2 (g) + \text{Ca(OH)}_2 (aq) \]
Here, calcium carbide reacts with water to produce acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2).

3. **Identify the Product**:
The product of the reaction that is a flammable gas is acetylene (C2H2).

4. **Conclusion**:
Therefore, the reaction of solid calcium carbide with water produces acetylene, which is a flammable gas.

### Final Answer:
The reaction of solid calcium carbide with water produces acetylene (C2H2), a flammable gas.
