Answer 1

Answer:

DISPLACEMENT REACTION - DEFINITION

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. For example,

Mg(s)+CuSO

4

(aq)⟶MgSO

4

(aq)+Cu(s)

Answer 2

Answer:

Displacement Reaction

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal. A + B-C → A-C + B. The above equation exists when A is more reactive than B.

Decompoultion Reaction

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB→A+B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
