A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. For example water (H₂O) is a chemical compound made of two elements (hydrogen and oxygen).

There are no chemical bonds between substances in the mixture.,For example, mixture is solution of water and alcohol.
