Question

In distillation components of a mixture are separated into groups of molecules with simi- lar
1. densities.
2. melting points. 3. None of these 4. bond energies. 5. boiling points.

Filtration is which method of separation? 1. physical
2. chemical

Answer 1

Fractional distillation separates mixtures by their boiling point.
To answer #2 you must know what a physical change is and what a chemical change is. In a physical change the material never changes its comp;osition. IN a chemical change the composition changes. So when you filter something do you change the copmposition or not.
