How do you Balance Pb(No3)2 and KI?

The balanced chemical equation for the reaction between lead (II) nitrate (Pb(NO3)2) and potassium iodide (KI) is:

Pb(NO3)2 + 2KI -> PbI2 + 2KNO3

This equation is already balanced as it has the same number of atoms of each element on both sides of the reaction arrow.
