Pour the oil and sand in a glass of water. The sand will sink to the bottom, and the oil will float to the top of the water.
My best guess is that you would filter the sand and then because oil and water cannot dissolve in each other you could diffuse the oil (pour it out of the container).
by filtering and distillation
This is the procedure:1. Strongly shake the mixture.2. Filter the mixture.3. Sand and ad iron remain on the filter.4. Extract iron with a magnet.5. Leave the filtrate for decantation.6. Separe oil with a separation funnel.7. Heat the solution.8. Water is vaporized.9. Salt remain as crystals.
sand Answer 2 This is not a very good example of a heterogeneous mixture because sand on its own is not really a mixture. It's just sand, whereas a mixture of sand and salt would be a mixture, and a heterogeneous one. However, it would be reasonable to say that each grain of sand itself is a mixture of various types of stone (mainly silica) so, at a pinch, the answer is correct, but a better example could be found.
spin it out! - Oil will come to the top
You just need to use filter paper. use the filter paper than just pour the water and sand on the filter paper. the sand will go to the filter paper while the water will go straight to the beaker or anything below it. That is how you separate it. To separate sand and water you could pour the mixture through a filter. The water would pass through the filter but the sand would remain on top of the filter. If you didn't need to save the water you could evaporate the water and leave the dry sand behind. Or allow the sand to settle and carefully pour off the water first. Then allow the remaining water to evaporate.
As the amount of emulsifier increases the time taken for the mixture of oil and water to separate will also increase. It is directly proportional.
Yes - in that the water is no longer pure... No - in that the salt can be reclaimed from the water by evaporation. The salt and the water are separate substances. The salt is said to be 'in suspension'.
#1 remove the oil by separating funnel , the oil will float on the water. #2 magnet to remove the steel filings (Note the spelling) #3 filter to remove the sand . #4 evaporate to remove the water , and leave the salt.

Oil and water. When oil is placed in water the oil falls to the bottom and the water stays at the top because it is lighter. Or, Salt and sand. To seperate them: If you take salt and put it through a funnel the salt dissolves into the water and the water evaporates leaving the salt on the bottom, and the sand on the top where it is too big to go through the funnel.
salt in water is a homogeneous mixture
By fractional distillation. Heat the mixture gently. As the temperature rises both liquids will evaporate and should be cooled and the condensate collected. The temperature will stabilise at around 78 deg C when all the remaining ethanol will evaporate.What you are left with is pure water. The condensate is mainly ethanol with a small quantity of water. It can be distilled again to increase its purity.
The atmosphere (Mixture of Oxygen, Nitrogen, and other gases. The ocean (Mixture of water, various salts)
coffee grounds, water, oil, and salt. We have access to all of the high school lab equipment, but were given no directions on how to separate these substances. I know how to separate salt from water by evaporation, but I have no clue how to separate any of the others.

Yes
It is virtually impossible to separate salt and water with a sieve unless the two materials have not been touched. This is because when salt is combined with water, it dissolves, and then it is mixed in with the water. To separate these two materials, you have to let the water evaporate, so then the salt is left.
Distillation.
