• For example, a mixture of salt in water.

Compound:

• A pure substance constituted of two or more elements combined chemically in a fixed ratio is called a compound.
• It can be split into these simpler and different substances by chemical means.
• For example, Common salt

Common salt$\left(\mathrm{NaCl}\right)$:

• Common salt is a compound made up of Sodium and chlorine atom.
• These elements are combined chemically in a fixed ratio to form Common salt.
• We can not separate these components easily by physical means.
