1) combination reaction- Those reactions in which two or more substance combine to form a single substance are called combination reaction.
2)decomposition reaction - those reactions in which a compound breaks up into two or more sub simpler substances .
3)displacement reaction - those reactions in which a more reactive element displaces the less reactive element .
4)double displacement reaction - those reactions in which two compounds react by the exchange of iron to form an insoluble solid.
so the reaction is also called as precipitation reaction .
Hope this helps :)

There are total 9 types of the chemical reactions.
They are named as follows :-
1. Combination reaction
When 2 or more reactants combine in a reaction to form a single product, it is called as Combination reaction.
Example
2Mg + O2 ==> 2MgO
2. Decomposition reaction
The chemical reactions in which two or more products are formed from a single reactant is called a decomposition reaction.
Example
CaCO3 ==> CaO + CO2
3. Displacement reaction
The reaction in which the place of ion of a less reactive element in a compound is taken by another more reactive element by formation of its own Ion is called a displacement reaction.
Example
CuSO4 + Zn ==> ZnSO4 + Cu
4. Double Displacement reaction
The reactions in which the ion in the reactants are exchanged to form a precipitate are called double displacement reactions .
Example
AgNO3 + NaCl ==> AgCl + NaNO3
5. Endothermic Reaction
The chemical reactions which are accompanied by absorption of heat are called endothermic reactions.
Example
CaCO3 + Heat ==> CaO + CO2
6. Exothermic reaction
The chemical reactions which are accompanied by evolution of heat are called Exothermic reaction.
Example
CaO + H2O ==> Ca(OH)2 + Heat
7. Reduction Reaction
The chemical reaction in which hydrogen is gained and oxygen is losed is called as Reduction Reaction.
Example
C + 2H2 ==> CH4
8. Oxidation Reaction
The chemical reaction in which a reactant combines with oxygen or loses hydrogen is called as Oxidation Reaction.
Example
MgH2 ==> Mg + H2
9. Redox Reaction
The chemical reaction in which both reduction and oxidation reaction takes place simultaneously is called Redox Reaction.
Example
CuO + H2 ==> Cu + H2O
These are the types of reaction.
