PREDICTING PRODUCTS
SYNTHESIS
Hint: Look for reactants that are both elements
If one is a metal and the other is a nonmetal, combine the reactants using the “Criss Cross” method
TRY PREDICTING THE PRODUCTS OF THIS REACTION AND THE BALANCE:
Na (s) + Cl2 (g)
DECOMPOSITION
Hint: Look for a single reactant
Break it into its elements
TRY PREDICTING THE PRODUCTS OF THIS REACTION AND THEN BALANCE:
CaBr2
COMBUSTION
Hint: The reactants will be oxygen and some hydrocarbon
The products are always the same!
(Carbon Dioxide and Water)
TRY PREDICTING THE PRODUCTS OF THIS COMBUSTION REACTION AND BALANCE
C2H14 + O2
SINGLE REPLACEMENT
Hint: Look for a compound and a single element.
The single element will replace the part of the compound that it is like. Metals replace metals (cationic), nonmetals replace nonmetals (anionic).
SINGLE REPLACEMENT
You must check the Activity Series to see if a single replacement reaction will actually occur.
Elements higher on the list can bump out the elements below them.
Use “Criss Cross” to write the formula of the new product

ZnCl2 + Br2
DOUBLE REPLACEMENT
Hint: Look for two compounds
Elements switch partners so that there is still a nonmetal with a metal in each compound.
Use Criss Cross when writing formulas for final products
DOUBLE REPLACEMENT
You must check the solubility chart to see if a double replacement reaction will occur.
You must have at least one product that is not soluble (forms a solid precipitate in solution) or there is no reaction
DOUBLE REPLACEMENT
SolubilityNot soluble = will not dissolve,
forms a precipitate in solution Marked with (s) to show that the
product is a solid
Soluble = will dissolve in solutionMarked with (aq) to show that the
product is dissolved in water
