Answer

Explanation:

Step1: Count phosphorus atoms on left - hand side

On the left - hand side of the equation (2P + 3Cl_2\rightarrow PCl_3), the number of phosphorus atoms is 2.

Step2: Balance phosphorus atoms

To balance the phosphorus atoms according to the law of conservation of mass, the number of phosphorus atoms on the right - hand side should also be 2. Since each (PCl_3) molecule has 1 phosphorus atom, the coefficient of (PCl_3) must be 2 so that there are 2 phosphorus atoms on the right - hand side.
