You need to separate a mixture of iron filings, sand, and salt. Which of the three would be easiest to separate first and what method would be best?
A) The salt would be easiest to separate, and using a magnet would be the best method.
B) The iron filings would be easiest to separate, and using a magnet would be the best method.
C) The salt would be easiest to separate, and using hot water to dissolve the other substances would be the best method.
D) The sand would be easiest to separate, and using hot water to dissolve the other substances would be the best method.
My answer is B
Yes, B.
You are correct, the iron filings would be the easiest to separate. The best method to separate the iron filings from the mixture would indeed be by using a magnet. By moving the magnet around the mixture, the iron filings will be attracted to the magnet and easily separate from the sand and salt. Therefore, option B is the correct answer.
You are correct! The easiest substance to separate out of the mixture of iron filings, sand, and salt would be the iron filings. The best method to use in this case would be to use a magnet.
To separate the iron filings using a magnet, you can follow these steps:
1. Place a magnet near the mixture of iron filings, sand, and salt.
2. Move the magnet slowly across the mixture.
3. The magnet will attract and pick up the iron filings, leaving the sand and salt behind.
By using a magnet, you can easily separate the iron filings from the other substances present in the mixture.
