This document discusses a chemical reaction where potassium chlorate (KClO3) decomposes into potassium perchlorate (KClO4) and potassium chloride (KCl). The chemical equation shows that in the reaction, one potassium atom and one chlorine atom are conserved on both sides, while the oxygen atoms are redistributed with the oxygen content changing from 3 to 4.
