Write an equation to show the reaction between Plaster of Paris and water

Explanation

To write the equation for the reaction between Plaster of Paris (POP) and water, we need to follow these steps:

### Step 1: Identify the chemical formula of Plaster of Paris
Plaster of Paris is chemically represented as calcium sulfate hemihydrate, which has the formula:
\[ \text{CaSO}_4 \cdot 1.5\text{H}_2\text{O} \]

### Step 2: Identify the product formed when Plaster of Paris reacts with water
When Plaster of Paris reacts with water, it forms gypsum, which is calcium sulfate dihydrate. The chemical formula for gypsum is:
