Why is ΔHvap for water much greater than ΔHfus? What does this reveal concerning changes in intermolecular forces in going from solid to liquid to vapor?
Answer to relevant QuestionsIn what array (simple cubic, body-centered cubic, and face-centered cubic) do atoms pack most efficiently (greatest percent of space occupied by spheres)? Support your answer mathematically. Titanium metal has a body-centered cubic unit cell. The density of titanium is 4.50 g/cm3. Calculate the edge length of the unit cell and a value for the atomic radius of titanium. (Hint: In a body-centered arrangement of ...Explain how a p–n junction makes an excellent rectifier. Assume the two-dimensional structure of an ionic com-pound MxAy is What is the empirical formula of this ionic compound? MnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47 × 10–8 cm, and the density of MnO is 5.28 g/cm3. a. Does MnO crystallize in the NaCl type or the CsCl type ...
