[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will define and give general equations for combination, decomposition, single-replacement, and double-replacement reactions. They will classify a reaction as combination, decomposition, single-replacement, double-replacement, or combustion and use the activity series to correctly predict whether a given reaction will occur. Lastly, students will predict the products of simple reactions, given only the reactants.
