Types of Chemical Reactions

Austin Abernathy

Synthesis

Definition: The production of chemical compounds by reaction from simpler materials.


Equation: A+B ------> AB


Example: Mg + O2 ---> MgO

Decomposition

Definition: The state or process of rotting; decay.


Equation: AB → A + B


Example: Ca(OH)2 ---> CaO + H2O

Single Replacement

Definition: A chemical reaction in which one element takes the place of another element in a compound.


Equation: AX + Y ---> YX + A


Example: Cu + AgNO3 ---> Ag + Cu(NO3)2

Double replacement

Definition: A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions.


Equation: AB + XY ---> AY + XB


Example: KOH + H2SO4 ---> K2SO4 + H2O
