A surprising amount of energy is released by the reactants and in the process their atoms and molecules rapidly rearrange to form the products carbon dioxide, water and potassium chloride. Chemical Change: 2. A gummy bear is dropped into an ignition tube containing a small amount of molten potassium or sodium chlorate. I have no idea what potassium chlorate is (so I was never much of a chemist, sue me. Iron rusts. 136. share. Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO 3.In its pure form, it is a white crystalline substance. After heating, it decomposes to $\ce{O2}$ and $\ce{KCl}$: $$\ce{4 KClO3 → KCl + 3 KClO4}$$ $$\ce{KClO4 → KCl + 2O2}$$. Long laboratory tweezers Face shield .
