Mixtures differ from compounds as follows:
1. A mixture is heterogeneous, except solutions which are homogeneous.
2. The components of a mixture may be present in any proportion.
3. Properties of a mixture are the average properties of the components.
4. The components of a mixture can be separated by simple physical methods.
5. During the preparation of a mixture, no heat, light or electricity is absorbed or evolved.
1. A chemical compound is always homogeneous.
2. The components of a compound are present in a fixed proportion.
3. Properties of a compound are entirely different from those of the component elements.
4. The components of a compound cannot be separated by simple physical methods.
5. Formation of a compound generally leads to the absorption or evolution of heat, light or electricity.
