Which of the following are decomposition reactions? 1. CH4 (g) + O2 (g) → CO2 (g) + H2O (l) 2. CaO (s) + CO2 (g) → CaCO3 (s) 3. Mg (s) + O2 (g) → MgO (s) 4. PbCO3 (s) → PbO (s) + CO2 (g). The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category. Combinations There are also two types of combinations (remember the order does not matter now): Repetition is Allowed: such as coins in your pocket (5,5,5,10,10) No Repetition: such as lottery numbers (2,14,15,27,30,33) 1. Combinations with Repetition Actually, these are the hardest to explain, so we will come back to this later. 2.
