1. How would you separate a mixture of sand, iron nails, and sea salt?
We all know that nails are attracted to magnets. So first, use a magnet to attract the iron nails. We also know that salt dissolves in water, while sand does not. So add water to dissolve the salt and leave out the sand. Now, filter the sand out, and then heat the salt solution to get rid of the water. There you have it.
2. In nature most things exist as mixtures. False or True
True. Don’t look far. Think about the food you eat. Most are mixtures.
