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
