Answer

Explanation:

Step1: Count phosphorus atoms

On the left - hand side, in $P_4$, there are 4 phosphorus atoms.

Step2: Balance phosphorus

To balance the phosphorus atoms, if we have $PCl_3$ on the right - hand side, we need 4 moles of $PCl_3$ since each $PCl_3$ has 1 phosphorus atom. So the balanced equation is $P_4(s)+6Cl_2(g)\rightarrow4PCl_3(l)$.
