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
