When salt is mixed with water and stirred, the salt will dissolve, forming a solution. when sand is mixed with water, the sand will not dissolve. why will salt form a solution with water but sand will not? a) salt is pulled apart into two ions by the polar water molecules, and sand is not. b) sand forms complex crystals which dissolve much more slowly than non-crystalline salt. c) salt consists of only 2 atoms and is small enough to dissolve, while sand is too large. d) sand is much harder than salt and so it will not form a solution with water.

The earth only has a limited supply of fresh water; eventually, we will have to use ocean water. we will purify ocean water through a process called desalinization. currently, it is not profitable to purify ocean water. how would this change in the future? the risk of running out of water could mean that it becomes more profitable to purify ocean water. water could become expensive, and then it would become profitable to purify ocean water. it takes a lot of energy to purify ocean water, but if people are willing to pay a lot, then it will become profitable. all of the above.
