Question

Difference between a compound and a 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.

Answer 2

Answer:

• Compound

• Made from elements chemically bonded together.

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

• It has fixed melting and boiling point.

• Composition of a compound is fixed. It has definite formula.

♡ Example:- Water

• Mixture

• It consists of two or more elements or compound not chemically combined together.

• It shows properties of it's constituents.

• It doesn't have fixed melting and boiling point.

• Composition of a mixture is variable.

♡ Example:- Air, salt solution.
