Predicting Double Replacement
Predicting Combustion

3. Predicting Products
If given reactants, you should be able to predict the products.
The type of reactants will tell you which type of reaction will happen.
Given Reactants
Determine Reaction Type
Predict Products
Two elements.
Synthesis (S)
A single compound
Decomposition (D)
An element and a compound
Single replacement (SR)
Two compounds
Double replacement (DR)
Reaction with oxygen
Combustion (C)

4. Predicting Double Replacement
Use when two ionic compounds are reacting.
Identify the cations and anions present in the reactants.
Switch partners so that each cation is with the other anion.
Write your products using the “switch drop and reduce” procedure for new compounds.
Check solubility to verify the reaction happens.
Ex: CaCl2 + AgNO3 
Ex: ZnSO4 + Ba(OH)2 

5. Predicting Combustion
Use when there is oxygen as a reactant.
Identify each element in the other reactant.
The products formed will be oxides of each of the elements.
Common Nonmetal oxides are CO2, H2O, NO2 and SO2.
For metal oxides, use the “switch drop and reduce” procedure (Metal ion to use given.)
Ex: C3H3NO + O2 
Ex: (III) FeS + O2 

6. Predicting Products
