There are four type of chemical reaction:
* Combination reaction
In this reaction two or more elements or compounds join to to form a single compound.
A + B ---› AB
Ex: 2H2 + O2 = 2H2O
* Decomposition reaction
In this reaction a compound gets decomposed into simpler substance
AB ---› A + B
Ex: 2MgO ---› 2Mg + O2
* Displacement reaction
In this reaction a element displaces another element from its compound.
A + BC ---› AC + B
Ex: Fe + CuSO4 ---› FeSO4 + Cu
* Double displacement reaction
In this reaction compounds exchange there elements.
AB + CD ---› AC + BD
Ex: HCl + NaOH ---› NaCl + H2O
