Types of Chemical Reactions

Regan Coppage

Synthesis

The production of a substance by combining simpler substances through a chemical process resulting in one product.


A+B = AB


Mg + O2 ---> MgO
H2 + O2 ---> H2O
K + Cl2 ---> KCl
Fe + O2 ---> Fe2O3

Decomposition

The production of a substance by breacking down a substance through a chemical process resulting in two or more products.


AB = A+B


HgO ---> Hg + O2
H2O ---> H2 + O2
MgCl2 ---> Mg + Cl2
FeS ---> Fe + S

Single Replacement

A type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another.


AX + Y = YX + A
Cu + AgNO3 ---> Ag + Cu(NO3)2
Fe + Cu(NO3)2 ---> Fe(NO3)2 + Cu
Ca + H2O ---> Ca(OH)2 + H2
Zn + HCl ---> ZnCl2 + H2

Double Replacement

A type of reaction that occurs when the cations and anions switch between two reactants to form new products.


AB + XY = AY + XB


CaCO3 + HCl ---> CaCl2 + CO2 + H2O
K2SO3 + HNO3 ---> KNO3 + SO2 + H2O
NH4Cl + NaOH ---> NaCl + NH3 + H2O

combustion

A rapid chemical combination of a substance with oxygen, involving the production of heat and light.


CxHy + O2 ---> CO2 + H2O


CH4 + O2 ---> CO2 + H2O
C2H6 + O2 ---> CO2 + H2O
C6H12O6 + O2 ---> CO2 + H2O
C2H5OH + O2 ---> CO2 + H2O
