Answer 17

harder

Question 18

gases stay dissolved at ____ temperatures

Answer 18

cool

Question 19

saturated solutions

Answer 19

a solution has the maximum amount of solute dissolved in the solution at a specific temperature

Question 20

supersaturated solution

Answer 20

a solution has more than the maximum amount of solute dissolved in the solution at a specific temperature

Question 21

unsaturated solution

Answer 21

a solution has less than the maximum amount of solute dissolved in the solution at a specific temperature

Question 22

unsaturated solutions can be made by-

Answer 22

dissolving solute at a higher temperature before slowly cooling it down to a lower temperature without the solute crystalizing

Question 23

supersaturated solution is-

Answer 23

unstable and can crystalize easily if agitated or cooled too quickly

Question 24
