what happens when NaCl(s) is dissolved in water?
(1)Cl-ions are attracted to the oxygen atoms of the water
(2)Cl-ions are attracted to the hydrogen atoms of the water.
(3)Na+ions are attracted to the hydrogen atoms of the water.
(4)no attractions are involved; the crystal just falls apart.

Crystals dissolve in water because the heat of solution of the ions is enough to overcome the lattice forces holding the crystal together. The water molecules are dipoles with the H end positive and the O end negative. The negative end of water molecules is attracted to the Na^+ and the positive end of the water molecules is attracted to the Cl^- ions. Look in the answers where opposite charges attract (because like charges repel so those won't happen).
