Explanation:

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
