Question

Give the difference between compound and mixture ( 4 points)​

Answer 1

${\mathfrak{\pink{\underline{\underline{Compound:-}}}}}$

★ It is obtained by the chemical combination of more than one element.

★ The composition of elements present in a compound is fixed.

★ It may or may not show the properties of its constituent elements.

★ Its constituents can be separated by using only chemical and electro chemical methods.

${\mathfrak{\pink{\underline{\underline{Mixture:-}}}}}$

★ It is obtained by the physical combination of either elements, or compounds, or both.

★ The composition of elements present in a mixture is not fixed.

★ It shows the properties of all its constituents.

★ Its constituents can be separated using physical methods.

Answer 2

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.
