Question

Differences between mixtures and compounds ​

Answer 1

Differences between mixtures and compounds are :-

Mixture

• In a mixture, the elements or compounds just mix together.

• The components of a mixture may be present in any ratio.Its composition is variable.

• There is no new substance formed.

• A mixture does not have a definite formula.

• A mixture may be homogeneous or heterogeneous.

• No chemical reaction takes place and therefore, the formation of mixture is not accompained by any energy change.

• A mixture shows the properties of its constituents.

• A mixture can be separated into its constituents by physical methods (like filtration, evaporation, distillation,

sublimation, mechanical separation, etc.)

• A mixture does not have fixed melting point, boiling point,etc.

Compound

• The elements combine or react to form compounds .

• The compound contains two or more elements in a fixed ratio by mass. Its composition is always fixed.

• A new substance is formed.

• A compound has a definite formula.

• A compound is always homogeneous.

• The compounds contain two or more elements in a fixed ratio

• A chemical reaction takes place and therefore, the formation of a compound takes place with absorption or evolution of heat.

• The properties of a compound are entirely different from those of its constituents.

• A compound cannot be separated into its constituents by ordinary physical methods. These can be separated by chemical or electrochemical reactions.

• A compound has a fixed melting point, boiling point, etc.

Answer 2

Answer:

Explanation:A compound is made up of two or more different elements that are chemically combined in fixed ratios and can be separated chemically not physically.

While mixture is made up of two or more different substances that are physically combined but not in fixed ratios and are of two types homogeneous or heterogeneous mixture.
