The correct Answer is:
To solve the question regarding the gas evolved on heating sodium carbonate (Na₂CO₃), we can follow these steps: ### Step 1: Understand the compound Sodium carbonate, commonly known as washing soda, is represented by the chemical formula Na₂CO₃. ### Step 2: Research the thermal decomposition of Na₂CO₃ When sodium carbonate is heated, it does not undergo thermal decomposition like some other carbonates (e.g., calcium carbonate). Instead, it remains stable and does not release any gas. ### Step 3: Conclusion Since sodium carbonate does not decompose upon heating and does not produce any gas, we conclude that no gas is evolved when Na₂CO₃ is heated. ### Final Answer The gas evolved on heating Na₂CO₃ is **none** (or **no gas**).
