Answer 1

ANS: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-The opposite of a combination reaction – a complex molecule breaks down to make simpler ones.AB → A + B

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
