Warm-Up!  Balance the equations:

Types of Chemical Reactions 3/18/14

The 5 Main Types Reaction TypeGeneral Form Synthesis (combination) A+B→AB Decomposition AB → A+B Combustion Hydrocarbon + O 2 → CO 2 + H 2 O Single Replacement AB+C→AC+B Double Replacement AB + CD → CB + AD

Synthesis  Example:  Hint: always forms one product

Decomposition  Example:  Hint: always has one reactant

Combustion  Example:  Hint: always reacts with oxygen and forms water + carbon dioxide

Single Replacement  Example:  Hint: an element and an ionic compound react—one lonely element on each side

Double Replacement  Example:  Hint: two ionic compounds exchange ions

Predicting Double Replacements  Exchange cations (1 st ion) of the two reactants  Create new products using favorite charges of elements or polyatomics  Balance the equation

Double Repl. Example  K OH + H 3 PO 4 →  K 3 PO 4 + H 2 O  Ba Cl 2 + K 2 CO 3 →  Ba CO K Cl
