Question 42 Why does the vapor pressure of water decrease when we add NaCl to it? A The ion-dipole attractions of the water to the NaCl, since stronger than water'd H-bonding, make water less willing to evaporate. B с The vapor pressure actually increases because water wants to get away from the NaCl and try to be pure again. E Only the liquid at the surface evaporates, so when we add the NaCl, some of it will take up some of the surface spots decreasing the amount of water molecules who have the opportunity to evaporate. (D) None of these are correct. Since the water is now trying to separate the sodium ions Wom the chloride ions, the water molecules are too busy to evaporate.

Using the graphic below, what can be said about the strength of the intermolecular forces (IMFS) of water in the Step 2 compared to Step 4? Heating Curve of Water 100 50 Time ---> O The IMFS solid water are stronger in liquid water and this is seem by the shorter length of Step 2 compared to Step 4 O The IMFS of liquid water are stronger than in solid water and this is seen by the longer length of the segment of Step 4 compared to Step 2 The IMFS of solid water are stronger than in liquid water and this is seen by the longer length of the segment of Step 4 compared to Step 2 The IMFS of liquid water are stronger in solid water and this is seem by the shorter length of Step 2 compared to Step 4 (0.) amaradL
How is "hard" water made "soft"? Explain why that process works.
Question 9 One reason ionic compounds do not dissolve well in nonpolar solvents is that there are no forces of attraction between ions and nonpolar molecules. O ion-solvent interactions are not strong enough to solvate the ions in solution. O ion-dipole interactions are too large for effective solvation to occur. not all cations and anions have the same magnitude of charge and therefore do not form neutral ion pairs. uestion 8 Large intermolecular forces in a substance are manifested by high boiling point high heats of fusion and vaporization high critical temperatures and pressures low vapor pressure O all of the above
