Types of Chemical Reactions

Combustion

a hydrocarbon (compound made of carbon and hydrogen) reacts with oxygen gas which produces carbon dioxide and water

4 C5H9O + 27 O2 -> 20 CO2 + 18 H2O

combustion

C3H6O + 4 O2 -> 3 CO2 + 3 H2O

combustion

C6H12 + 9 O2 -> 6 CO2 + 6 H2O

combustion

2 NO2 -> 2 O2 + N2

decomposition

CaCO3 -> CaO + CO2

decomposition

O3 -> O. + O2

decomposition

2 MgI2 + Mn(SO3)2 -> 2 MgSO3 + MnI4

double replacement

2 RbNO3 + BeF2 -> Be(NO3)2 + 2 RbF

double replacement

Na3PO4 + 3 KOH -> 3 NaOH + K3PO4

double replacement

Decomposition

one compound splits into two or more pieces, which can be elements or simpler compounds

Single replacement

one element replaces another element in a compound forming a new compound

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

single replacement

Pb + FeSO4 -> PbSO4 + Fe

single replacement

SeCl6 + O2 -> SeO2 + 3Cl2

single replacement

2 C5H5 + Fe -> Fe(C5H5)2

synthesis

2 NH3+ 1 H2SO4 -> 1 (NH4)2SO4

synthesis

P4 + 3 O2 -> 2 P2O3

synthesis

Double replacement

the cations and anions of two different compounds switch

Synthesis

two or more elements or simple compounds come together to form one compound
