The 5 Main Types

Reaction Type General FormSynthesis (combination)

A+B→AB

Decomposition AB → A+BCombustion Hydrocarbon + O2

→ CO2 + H2OSingle Replacement AB+C→AC+BDouble 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 (1st ion) of the two

reactants Create new products using favorite

charges of elements or polyatomics Balance the equation

Double Repl. Example KOH + H3PO4 →

K3PO4 + H2O

BaCl2 + K2CO3 → BaCO3 + 2KCl
