Explanation:
Ans- The differences between compounds and mixtures are
Mixtures
1. Constituents are combined together notchemically but physically only.
2. Constituents can be present in any ratio.
3. Elements or compounds just mix togetherto form a mixture and no new compound is formed.
4. Constituents can be separated by physicalmethods.
5. A mixture shows the properties of the constituent substances.
6. Often no energy is absorbed or released when a mixture is formed.
7. Soil, Sugar solution. Air. Sea water etc.
Compounds
1. Constituents are combined together chemically.
2. Same constituents are present in a fixedratio.
3. Elements react to form new compounds.
4. Constituents can be separated only by chemical methods.
5. A compound shows the properties different from those of their constituents
6. Often energy is absorbed or released
during the formation of compounds.
