The five types of reactions are Synthesis, Decomposition, Single Displacement, Double, and Combustion.
Synthesis- Two or more substances combine to form another more complete substance
Decomposition-opposite of synthesis
Single-Displacement- occurs when one element replaces another element in a compound
Double- Displacement- Two different atoms in two different compounds exchange places.
Combustion- A hydrocarbon reacts with oxygen.
Synthesis- fe + o2 ---> Fe2O3
Decomposition- NaHco3 ----> H2O + CO2 + NNaoH
Single Displacement- Fe + Cuso4 ---> Cu + Fe(So4)3
