Question

five differences between compound and mixture

Answer 1

Compounds

1. Compounds are pure substances.

2. They are made up of two or more elements combined chemically.

3. The constituents of a compound are present in a fixed ratio.

4. Compounds have fixed properties. For example, a particular compound will have fixed temperatures at which it melts and boils.

5. A compound can have properties different from its constituents, as a new substance is formed when the constituents are chemically combined.

6. The constituents of a compound can be separated only by chemical methods.

Mixtures

1. Mixtures are impure substances.

2. They are made up of two or more substances mixed physically.

3. The constituents of a mixture are present in varying ratios.

4. Mixtures do not have fixed properties. Their properties depend on the nature of their compo­nents and the ratios in which they are combined.

5. In mixtures, no new substance is formed. The properties of a mixture are the same as the properties of its constituents.

6. The constituents of a mixture can be separated easily by physical methods.
