1. Predicting Products
Decide what type of reaction it is based on what the reactants given.
Figure out what will happen to the reactants (how they will react)

2. TIP: Remember the exceptions
TIP: Remember the exceptions! See “Types of Reactions” Notes from the very beginning of this unit.

3. Combination/Synthesis
A + B  AB
Probable Product: A single compound
Mg + O2 

4. Decomposition
AB  A + B
Probable Product: More than 1 compound and/or element
Ca(OH)2 

5. Single Replacement A + BC  AC + B
Probable Product: A single element and new compound
Use activity series to determine if a reaction will happen!
Cu + AgNO3

6. Double Replacement AB + CD  AD + CB
Probable Product: Two new compounds
Use solubility rules to determine which product is the precipitate and (if any) which are spectators

7. Precipitate Predictions
Use the solubility chart to determine if any of the products will be insoluble (ppt) from the aqueous reactants
Pb(NO3)2 + H2SO4 
Na3PO4 + AlCl3 

8. Combustion CxHy + O2  CO2 + H2O
Probable products (if reactant is a hydrocarbon): CO2 & H2O

9. Practice
K2O + H2O 
K2CO3 + BaCl2 
NaCl + F2 
C3H8 + O2 
