  1. 1. chemistry Slide 1 of 42
  2. 2. 11.2 Types of Chemical Reactions The heat and smoke of burning charcoal are the products of a combustion reaction. Combustion is one of the five general types of chemical reactions. If you can recognize a reaction as being a particular type, you may be able to predict the products of the reaction. © Copyright Pearson Prentice Hall Slide 2 of 42
