- Combination Reactions (two elements or compounds combine)
A + B - > AB
- Decomposition Reactions (something breaks down)
AB -> A + B
- Displacement Reactions (Switch reactants)
AB + CD -> AD + BC
- Demonstrations:
- Demonstrate Electrolysis of Water and balance equations
- H2O(l) -> H2(g) + O2(g) (Decomposition)
- H2(g) + O2(g) -> H2O(l) (Combination)
- Demonstrate mixing baking soda with vinigar makes a fizz (bring matches):
- Baking Soda + Viniger -> ?
- Sodium Bicarbonate + Acetic Acid (Hydrogen Acetate)
- NaHCO3(s) + HC2H3O2 (aq) -> Na+(aq) + H2O(aq) + CO2(g) + C2H3O2- (aq)
- Demonstrate precipitation of silver chloride
- NaCl(s) -> Na1+(aq) + Cl1-(aq)
- AgNO3 (s) -> Ag1+ (aq) + NO31-(aq)
- Ag1+ (aq) + Cl1-(aq) -> AgCl (s)
- NaCl (aq) + AgNO3 (aq) -> AgCl (s) + NaNO3 (aq)
- More Examples
- Fe(s) + Cl2(g) -> FeCl3(s) (Do this one on board)
- Fe(s) + Cl2 (g) -> FeCl2 (s)
- NaOH(aq) + H2SO4 -> Na2SO4 (aq) + H2O (l)
- NaOH (aq) + HCl -> H2O + Na+ (aq) + Cl- (aq)
- C8H18 + O2 -> CO2 + H2O
- KO2 (s) + H2O(g) + CO2 (g) -> KHCO3 (s) + O2 (g)
- CH4 (g) + O2 (g) -> CO2 (g) + H2O (g)
- C4H10 combustion
