Katie's teacher has given her a sample that contains a mixture of salt, sand, and iron fillings. She is instructed to separate the mixture into the three individual components. What would be the best physical property to focus on for the first step in separating the mixture?adensitybelectrical conductivitycmagnetismdmelting point

Mixtures can be separated based on the differences between the physical properties of the components.If you spilled a container of iron filings on the ground, how could you separate the iron filings from the soil using their different physical properties? A. Wait for the iron to rust and become orange. B. Light the mixture of soil and iron filings on fire. C. Use a magnet to remove the iron filings from the soil. D. Put the mixture in water and the soil will dissolve.

State the most appropriate separation technique for the following mixtures:1. Obtain water from a mixture of salt and water 2. Obtain salt from a beaker of salt solution 3. Obtain sand from a mixture of sand and water 4. Obtain iron filings from a mixture of iron filings and sand 5. Obtain components in a sample of black ink

How can a mixture of salt and sand be separated?A.By dissolving the salt in water and filtering out the sandB.By using a magnet to attract the sandC.By adding oil and collecting the layers of salt and sandD.By allowing the salt to evaporate

Design an experiment that would allow you to separate out a mixture of iron filings, sand and salt.
