Strategy:
 Balance the redox reaction between Lead Sulfide and Ozone. Identify the stoichiometric coefficients for ozone (X) and oxygen (Y) and sum them up.

Step 1: Balance the reaction

Here, Sulfur is oxidized from  to  (losing ). 4 moles of Ozone are reduced (each  acts as a  oxidant by losing one Oxygen atom).

Step 2: Sum the coefficients
