i ranked them 2, 1, 3
which of these are true?
1)smaller compounds are generally more soluble in water than larger compounds with similar structures
2)compounds that can form more hydrogen bonds are more soluble in water
3)larger compounds can form more hydrogen bonds than smaller compounds with similar structures

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
