Chemical Reaction Types :]

Types of Chemical Reactions. Now that you know that a chemical equation represents a type of chemical reaction, you can classify each reaction into one of four categories. The type of reaction is based on how the reactants change as they undergo a reaction and yield products.

**__Synthesis__** : two or more elements or compounds combine to form a more complex substance A + B ---> AB

**__Decomposition__** : a compound breaks down into simpler substances AB ---> A + B

 **__Single Replacement__** : one element replaces another in a compound A + BC ---> AC + B

**__Double Replacement__** : elements in one compound trade places with elements in another compound AB + CD ---> AD + CB
