17. Which of the following is a solution?

18. Which of the following is a solution?
All the rest are mixtures

19. Think like a scientist: What is the difference between a mixture and a solution?

20. Think like a scientist: What is the difference between a mixture and a solution
Solutions have a salute that can be completely dissolved in the solvent and a mixture is made up of 2 or more substances that can be separated by hand, magnet, strainer, or filter. Solutions can sometimes be separated by adding thermal energy to evaporate the solvent leaving the original salute.

A student made a mixture using equal amounts of salt and pepper. The salt grains were the same size as the pepper grains. What should the student do to most easily separate the pepper from the salt?
A. Use a pair of tweezers to remove each grain of pepper.
B. Put the mixture in water and filter the pepper out of the water.
C. Use a strainer with a fine wire screen to remove the pepper.
D. Run a small magnet through the mixture to attract the pepper.
