Chemistry 12 Assignment

Sugar is a fuel that we use for energy. We can also use it to fuel a chemical reaction. In this reaction, the sugar from the gummy bear reacts with the oxygen produced from the decomposition of potassium chlorate. Purple sparks form, which are a result of the potassium ion (It has nothing to do with the colour of gummy bear you use). As we heat the Potassium Chlorate it starts to decompose as follows: This produces oxygen which oxidizes the sugar (glucose) in the gummy bear. This oxidation is incredibly exothermic (-5000 kJmol-1). The reaction is: ** C6H12O6(s) + 6O2(g) ****à ****  6CO2(g) + 6H2O(g)  **
 * Introduction: **
 * 2KClO3(s) ****à ****  2KCl(s) + 3O2(g) **
