According to the bohr model of an atom, what happens when an electron moves from the second energy level to the third energy level and then back to the second energy level? energy is absorbed and then stored in the atom. energy is released and then absorbed to form an absorption line. energy is absorbed and then released to form an emission line. energy is released from the atom, and the outer level is weakened.

Asolution contains 225 g of sodium chloride, nacl, dissolved in enough water to make a 0.25 l of solution. what is the molarity of the solution? a. 3.88 m, b. 1.03 m, c. 1.5 m, d. 15.5 m

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.
