Write balanced equation for reaction of `PCl_(5)` with heavy water . ]

Explanation

To write the balanced equation for the reaction of phosphorus pentachloride (PCl₅) with heavy water (D₂O), we will follow these steps:

### Step 1: Write the unbalanced equation
The reactants are phosphorus pentachloride (PCl₅) and heavy water (D₂O). The products of the reaction are phosphorus oxychloride (POCl₃) and deuterium chloride (DCl). The unbalanced equation can be written as:

\[ \text{PCl}_5 + \text{D}_2\text{O} \rightarrow \text{POCl}_3 + \text{DCl} \]

### Step 2: Identify the number of each atom on both sides
