Diagram and explain the H-Bonds if they exist for the following molecules:
(a.)H2S, (b.)CH4, (c.)H2SO3, and (d) PH3.
Give reasons for the fact that ionic solids as NaCl have high melting points and dissolve readily in water, whereas network solids such as diamond have very high melting points and do not dissolve in water.
Determine the Osmotic Pressure for the following aqueous solutions @ 25 degrees Celsius. (a.) 1.0. M Glucose, and (b.)1.0 M NaCl. Explain which solution has the greater osmotic pressure if any and why.
Determine the effect on the freezing point and boiling point of the solvent for both solutions described in question number three above.
