Question

(i) Write any three points of difference between homogeneous and heterogeneous mixture.
(ii) Give two reasons for supporting the water is a compound not a mixture.

Answer 1

Homogeneous mixture	Heterogeneous mixture
The homogeneous mixture is one in which the particles are uniformly distributed within the container.	The heterogeneous mixture is one in which the particle or substances are not evenly spread or distributed.
These are called as solutions.	These are called as suspensions/colloids.
The particles appear smaller in size. EX: milk, gasoline, sugar solution, corn oil, fog etc.	The particles are either smaller or larger in size. EX: a mixture of mud & water, beach sand, vinegar, air cloud etc.

The compound nature of water can be attributed to the following two reasons

• The ration of hydrogen and oxygen in water remain same irrespective of its source.
• The water shows different property than its constituent element which is a property of the compound.
