      1. Combination Reactions (two elements or compounds combine)
      2. A + B - > AB

      3. Decomposition Reactions (something breaks down)
      4. AB -> A + B

      5. Displacement Reactions (Switch reactants)
      6. AB + CD -> AD + BC

    3. Demonstrations:
      1. Demonstrate Electrolysis of Water and balance equations
        1. H2O(l) -> H2(g) + O2(g) (Decomposition)
        2. H2(g) + O2(g) -> H2O(l) (Combination)
      2. Demonstrate mixing baking soda with vinigar makes a fizz (bring matches):
        1. Baking Soda + Viniger -> ?
        2. Sodium Bicarbonate + Acetic Acid (Hydrogen Acetate)
        3. NaHCO3(s) + HC2H3O2 (aq) -> Na+(aq) + H2O(aq) + CO2(g) + C2H3O2- (aq)

      3. Demonstrate precipitation of silver chloride
        1. NaCl(s) -> Na1+(aq) + Cl1-(aq)
        2. AgNO3 (s) -> Ag1+ (aq) + NO31-(aq)
        3. Ag1+ (aq) + Cl1-(aq) -> AgCl (s)
        4. NaCl (aq) + AgNO3 (aq) -> AgCl (s) + NaNO3 (aq)
