Types of Chemical Reactions

by: Ethyn West

Synthesis

-synthesis is the combining of the constituent elements of separate material orabstract entities into a single or unified entity

-Equation

A + B -> AB

-Example

When a metal or non-metal reacts with oxygen to form an oxide

Decomposition

-Decomposition is the state or process of rotting

-Equation

AB -> A + B

-Example

H2O -> H2 + O2

Single-Replacement

-Single-replacement is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another

-Equation

AB + C -> CB + A

-Example

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

Double-Replacement

-Double-replacement is a type of reaction that occurs when the cations and anions switch between two reactants to form new products

-Equation

AB + XY ---> AY + XB

-Example

FeS + HCl ---> FeCl2 + H2S

Combustion

-Combustion is the rapid chemical combination of a substance with oxygen, involving the production of heat and light

-Equation

CxHy + O2 ---> CO2 + H2O

-Example

C6H12O6 + O2 ---> CO2 + H2O
