Chemical reactions don’t just happen randomly. There is an underlying reason for why each reaction takes place and if we are to make a theory based on chemical reactivity we analyze various reactions and look at the trends. This allows a chemist to predict what might happen in a chemical reaction.
The reactions we will familiarize ourselves with in this section are: Combination Reactions, Decomposition Reactions, and Combustion Reactions.
