Question

You are presented with a mixture of iron beads and iron filings. how can you separate them? use a magnet dissolve the filings in water use a screen distillation

Answer 1

Answer: use a screen

Explanation: As the mixture is of iron beads and iron filings, they cannot be separated using magnet as both will be attracted towards the magnet.

Iron beads and iron filings do not dissolve in water and thus remain as such when dissolved in water.

Using a screen can help as size of iron beads and iron filings is different. Iron fillings being in powder form will sieve through the screen and iron beads will remain on the screen. Thus can be separated.

Distillation is used to separate mixture of two liquids.

Answer 2

I believe the correct answer from the choices listed above is the last option. You can separate the mixture of iron beads and iron filings by using a screen distillation. Since they surely have different sizes so you can easily separate by filtration. Hope this answers the question.
