Types of Chemical Reactions

Jackson Kolb

Synthesis

Synthesis-the production of chemical compounds by reaction from simpler materials. A + B -- AB

CaO + CO2 ---> CaCO3
Na2O + CO2 ---> Na2CO3
KCl + O2 ---> KClO3
Ba(ClO3)2 ---> BaCl2 + O2

Decomposition

Decomposition- analysis or breakdown is the separation of a chemical compound into elements or simpler compounds. AB-- A + B

2 H2O → 2 H2 + O2

Single Replacement

Single Replacement-


    A single-displacement reaction, also named single-replacement reaction, 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


    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

Double Replacement-A double displacement reaction, also known as a double replacement reaction or metathesis reaction, is a type of reaction that occurs when the cations and anions switch between two reactants to form new products. AB + CD--AD + CB

KOH + H2SO4 ---> K2SO4 + H2O
FeS + HCl ---> FeCl2 + H2S
NaCl + H2SO4 ---> Na2SO4 + HCl
AgNO3 + NaCl ---> AgCl + NaNO3

Combustion

Combustion-rapid chemical combination of a substance with oxygen, involving the production of heat and light.CH4 + O2 ---> CO2 + H2O
C2H6 + O2 ---> CO2 + H2O
C6H12O6 + O2 ---> CO2 + H2O
C2H5OH + O2 ---> CO2 + H2O

Always contains oxygen.
