Additional Information :-

Double-displacement reaction:-

• A type of chemical reaction in which two compounds exchange their ions to form two new compounds is called a double displacement reaction.

Exothermic reaction:-

• A reaction which releases energy in the form of heat or light to its surrounding during the formation of the products is called an exothermic reaction.

Displacement/Single-displacement reaction:-

• A type of chemical reaction in which an atom or a group of atoms displace another atom or group of atoms of a compound is called a displacement/single-displacement reaction.

Combination reaction:-

• A type of chemical reaction in which a single product is formed from two or more reactants is called a combination reaction.
