write the all types of chemical reaction with deffine and example.
Answers
The 5 primary types of chemical reactions are:
Combination reaction
Decomposition reaction
Displacement reaction
Double Displacement reaction
Precipitation Reaction
1. Combination Reaction
A reaction in which two or more reactants combine to form a single product is known as a combination reaction.
It takes the form of X + Y → XY
Combination reaction is also known as a synthesis reaction.
Example of combination reaction: 2Na + Cl2 → 2NaCl
2. Decomposition Reaction
A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction.
It takes the form of XY → X + Y
A decomposition reaction is just the opposite of combination reaction.
Example of a decomposition reaction: CaCO3 → CaO + CO2
The reaction in which a compound decomposes due to heating is known as a thermal decomposition reaction.
3. Displacement Reaction
A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution.
It takes the form X + YZ → XZ + Y
It is also called a substitution reaction
Example of displacement reaction: Zn + CuSO4 → ZnSO4 + Cu
4. Double Displacement Reaction
A chemical reaction in which ions gets exchanged between two reactants which form a new compound is called a double displacement reaction.
It takes the form of XY + ZA → XZ + YA
It is also called a metathesis reaction
Example of double displacement reaction:
BBaCl2 + Na2SO4 → BaSO4 + 2NaCl
5. Precipitation Reaction
A chemical reaction that involves the formation of an insoluble product (precipitate; solid) is called Precipitation reaction.
The reactants are soluble, but the product formed would be insoluble and separates out as a solid.
