Types of Chemical Reactions
Sean Wimpee
Synthesis
the production of chemical compounds by reaction from simpler materials.
A + B = AB
Decomposition
the state or process of rotting, decay.
2H2O2 - 2H2O + O2
Example: rotten fruit
Single Replacement
is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another - that is, one element is replaced by another in a compound.
A + BC --- B + AC
Double Replacement
is a type of reaction that occurs when the cations and anions switch between two reactants to form new products.
AB + CD - AD + CB
Combustion
rapid chemical combination of a substance with oxygen, involving the production of heat and light.
CH4 + 2O2 - CO2 + 2H2O
Example: fire
