The chemical equation `KClO_3 + P_4 -> P_4O_(10) + KCl` has to be balanced.

A balanced chemical equation has an equal number of atoms of each element on both the sides. It is also important to keep in mind that the molecules of any of the compounds that form the equation can only be present in whole numbers.

`KClO_3 + P_4 -> P_4O_(10) + KCl` 

Here, the compound `KClO_3` has 3 atoms of oxygen while `P_4O_(10)` has 10 atoms. This requires adding a coefficient of 10 to `KClO_3` and a coefficient of 3 to `P_4O_10`. To balance the phosphorus atoms, a coefficient of 3 has to be added to `P_4` and to balance the potassium and chlorine atoms a coefficient of 10 has to be used for KCl.

The balanced equation is: `10 KClO_3 + 3 P_4 -> 3 P_4O_(10) + 10 KCl`
