Answer it pls...

Dear student,

29) A homogenous mixture of alcohol and water can be separated by fractional distillations. 

Because boiling point of alcohol is 78.3 degree Celsius and the boiling point of water is 100 degree Celsius. 

When we perform fractional distillations and when we heat up the solution upon 78 degree Celsius, most of the alcohol present in the solution will be vaporize and can be collected separately but as the boiling point of water is 100 degree Celsius, so water will only remain in the vessel. Hence, they are separated.

Hence, the correct option is (b).

For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.
