9.) Density can separate two liquids because if one liquid is more dense than the other, then the less dense liquid will float to the top and the denser liquid will be below it separating them. With a test tube you can get the top liquid and separate it from the bottom liquid. These liquids also must be insoluble to be separated (meaning they don't mix together). 

10.) Acetone and Water would be the easiest to separate by distillation because Acetone has the lowest boiling point of the group and Water has the highest. 

11.) 

12.) 

13.) Simple distillation is the distillation of only two mixtures of crude oil while fractional distillation is  the distillation many more than two and are not completely distilled once finished.

14.) For light distillates there is fuel like gasoline to power cars and in intermediate distillates there is  heavy furnace oil to heat a furnace and in heavy distillates there is lubricating oil for cars and the pipes in cars. 

15.) I would expect the fraction with highest boiling point to be removed from the bottom of the distilled tower because it would most likely have a high density with a high boiling point which is why it would be at the bottom of the distilled tower. 

16.) To further separate the components again all you must do is go through the same process of fractional distillation again.
