16 Give reason: a) Cold water is passed through a condenser from lower to upper side during distillation. b) We cannot separate a mixture of alcohol and water by the use of separating funnel. c) Water is a compound and not a mixture.
Answers
Answer:
a-To absorb more he cold water is passed from lower side so that it will stay for longer time and absorb more heat from the vapours to form liquid state of the substance.
b-It is not possible to separate mixture of alcohol and water by using a separating funnel because these are not immiscible liquids. The mixture of alcohol and water can be separated by the process of distillation.
c-Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). ... It is not a compound because it is made from atoms of only one element - oxygen.
