1.Compound are substances which can be formed by chemically combining two or more elements.
1.Mixtures are substances that are formed by physically mixing two or more substances.
2.The chemical composition of compounds is always fixed.
2.A mixture can have a variable composition of the substances forming it.
3.Compounds are always homogeneous in nature.
3.Mixtures can either be homogeneous or heterogeneous in nature.
4.The properties of compounds are unique to themselves and need not necessarily reflect the properties of the constituent elements.
4.The constituents of a mixture does not lose their properties and so, the properties of a mixture are generally the sum of the properties of its constituents.
5.The constituents of a compound can only be separated by either chemical or electrochemical methods(like extraction).
5.Mixtures can be separated into their constituents via physical separation methods such as filtration. Thus, the separation of mixtures is relatively easier than the separation of chemical compounds.
6.The melting & boiling points of a compound are always defined.
6.The melting and boiling points of a mixture is not defined.
7.Example- Water, salt, baking soda, etc.
7.example- Oil and water, sand and water, smog (smoke + fog), etc.
