The correct Answer is:
To determine the chemical formula of product X obtained from the heating of CaSO₄·2H₂O at 392 K, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Reactant**: The reactant given is Calcium Sulfate Dihydrate, which has the chemical formula CaSO₄·2H₂O. 2. **Understand the Heating Process**: When CaSO₄·2H₂O is heated, it undergoes a process where water molecules are removed. At 392 K (which is approximately 119°C), the heating is sufficient to remove all the water of crystallization. 3. **Determine the Products**: - At lower temperatures (around 373 K or 100°C), heating CaSO₄·2H₂O results in the formation of Plaster of Paris (CaSO₄·0.5H₂O). - However, since we are heating at a higher temperature (392 K), all the water is removed, leading to the formation of anhydrous Calcium Sulfate. 4. **Write the Chemical Formula of Product X**: - The product formed after complete dehydration of CaSO₄·2H₂O at 392 K is anhydrous Calcium Sulfate, which has the chemical formula CaSO₄. 5. **Conclusion**: Therefore, the chemical formula of product X is CaSO₄. ### Final Answer: The chemical formula of product X is CaSO₄.
