Chemical Reactions I. Oxidation/Reduction Reactions 1. Combination Reactions: A + B AB 2Na (s) + Cl 2 (g) 2NaCl (s) 2. Decomposition Reactions: AB A + B 2LiClO 3 (s) 2LiCl (s) + 3O 2 (g) 3. Single Displacement: A + BC AC + B Ag 2 SO 4 (aq) + Cu (s) CuSO 4 (aq) + 2Ag (s) These do not always occur and are dependent on the relative activity of the reacting partners according to the activity series: Li >K >Ba >Sr >Ca >Na >Mg >Al >Mn >Zn >Fe >Cd >Co >Ni >Sn >Pb >H >Cu >Ag >Hg >Au In order for a reaction to occur the metal alone in the reactants must be more active (higher in the activity series) than the metal in the ionic species. In the example above, copper is more active than silver and thus will displace it from solution, however: CaCl

Combustion 2X + O 2 2XO 2Mg (s) + O 2 (g) 2MgO (s) When the species combusted is organic (containing carbon) the products are always the same: water and carbon dioxide CH 4 (g) + 2O 2 (g) CO 2 (g) + 2H 2 O (g) II. Metathesis Reactions (Double displacement) AB + CD CB + AD A. Precipitation reactions: when two soluble reactants react to form an insoluble product NaCl (aq) + AgNO 3 (aq) NaNO 3 (aq) + AgCl (s) The solubility rules must be used in order to help predict which compound(s) will precipitate when mixed. B. Neutralization reactions: reaction of an acid with a base to yield water and a salt HCl (aq) + NaOH (aq) NaCl (aq) + H 2 O (l)...
