Answer 2

Answer:

Explanation:

Simple distillation

Simple distillation is used when the boiling points of chemicals in a mixture having large differences (more than 25°C).

No fractionating columns used as the difference in the boiling point of mixture is large.

E.g. Process used in separating kerosene and petrol

Fractional distillation

Fractional distillation is used when the boiling points of chemicals in a mixture are close to each-other, usually within 77°F (25°C).

Fractionating columns used  to separate the mixtures.

E.g. Process used in the separation of Crude Oil into useful fractions
