Question

Define combination and displacement reaction.

Answer 1

Answer:

Combination reaction - A reaction in which two substances or elements join together to form a single substance is called combination reaction. ... Displacement reaction - A reaction in which a more reactive metal displaces a less reactive metal is called displacement reaction. example - Fe + - + Cu.

Answer 2

$\huge\bold\red{Combination\:Reaction}$

The reaction in which two or more reactants combine to form a single product is called combination reaction.
