Write balanced equation for the reaction : Phosphorus burns in chlorine gas to form phosphorus pentachloride.

Explanation

To write the balanced equation for the reaction of phosphorus burning in chlorine gas to form phosphorus pentachloride, we can follow these steps:

### Step 1: Write the unbalanced equation
The first step is to write the unbalanced chemical equation for the reaction. Phosphorus (P) reacts with chlorine gas (Cl₂) to form phosphorus pentachloride (PCl₅). The unbalanced equation is:
\[ P + Cl_2 \rightarrow PCl_5 \]
