Write a chemical equation to show the reaction of plaster of Paris with water. Give any two uses of plaster of Paris.

Explanation

### Step-by-Step Solution:

1. **Identify the Chemical Formula of Plaster of Paris**:
Plaster of Paris is chemically known as Calcium Sulfate Hemihydrate. Its chemical formula is represented as \( \text{CaSO}_4 \cdot \frac{1}{2} \text{H}_2\text{O} \) or \( \text{CaSO}_4 \cdot 0.5 \text{H}_2\text{O} \).

2. **Write the Reaction with Water**:
When Plaster of Paris reacts with water, it forms Gypsum, which is Calcium Sulfate Dihydrate. The reaction can be represented as:
\[
