  1. Physical Change Chemical Change OR ??

  2. PHYSICAL H2O (s)  H2O (l)

  3. CHEMICAL light 6CO2 (g)+6H2O (l) C6H12O6 (aq)+ 6O2 (g)

  4. PHYSICAL KMnO4 (s) K+ (aq) + MnO4- (aq)

  5. Hydrocarbons + O2  CO2 + H2O CHEMICAL

  6. CHEMICAL

  7. H2O (l) H2O (g) PHYSICAL

  15. PHYSICAL

  16. CHEMICAL

  17. How do we know a chemical reaction has occurred? • Heat or light is produced or absorbed • Gas evolved • The change is (generally) difficult to reverse • Change in colour* • Precipitate formed
