Types of Chemical Reactions
Single Replacement
AB + C ---> AC + B or CB + A
Part of an ionic compound is removed and replaced by a new element
FeS + 2HCl ---> H2S + FeCl2
Zn + 2 HCl → ZnCl2 + H2
2 Fe2O3 + 3 C → Fe + CO2
Double Replacement
AB + CD ---> AD + CB
Ionic compounds dissolved in water switch each others partners
Na2S + 2HCl →2NaCl + H2S
HCl + NaOH →NaCl + H2O
2KI + Pb(NO3)2 →2KNO3 + PbI2
Synthetis
A + B ---> AB
Two or more elements or compounds to form one product
4Fe + 3O2 --> 2Fe2O3
N2 + 3H2 ---> 2NH3
2SO2 + 02 ---> 2SO3
Decomposition
AB ---> A + B
One compound breaks into elements or smaller compounds
8Li2S ---> 16Li + S8
2Na2O2 ---> 2Na2O + O2
2H2O ---> 2H2 + O2
Combustion
A reaction between oxygen and a substance to produce an oxide and energy.
Two types: complete and incomplete
