Why does the vapor pressure of water decrease when NaCl is added to it? Use atomic or molecular properties to explain why calcium oxide has a much higher melting point (2580 degrees Celsius) than potassium fluoride (858 degrees Celsius). ...
3.2.1.1 Melting point Melting point is a valuable criterion of evaluation of any changes in the structure of an organic compound. The formation of prodrug is characterized by a change in melting point which is generally significantly different from that of either pure drug or lipid. The addition...
