How would you separate a mixture of Iron filings,sand,salt an wood chips (go into detail)

Answers

Answer 1

Answer: First I would use a magnet to get the iron filings out then I would use a sieve to separate the wood chips from the sand and salt. After this pour water into the sand and salt and put it through filter paper, the salt will go through as it is dissolved in water and the sand will be left behind. Place this salt solution into a dish and put it over a flame, the water will evaporate and leave the salt behind

we know that oil floats on water and do not mix

What happens to the oil when you first pour it in? It flows into the water, but then seperates.

Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same

What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans

Use a spoon to stir the oil for 30 seconds.
