What causes Cp to spike at a certain temperature when compounds are transitioning from solid to liquid

Explain the trend that bond formation does to atomic order by selecting all those that apply. Larger molecules have higher entropies than smaller molecules. Larger molecules have larger entropies on a per atom basis. Larger molecules have lower entropies than smaller molecules. Larger molecules have smaller entropies on a per atom basis.

Dispersion forces occur, because at any moment the electrons are unevenly distributed in an atom. True O False

Identify the compound with the smallest dipole moment in the gas phase. OHF OCHBr3 0 H2 O BrF O Nal

Chemistry 3. Calculate the dissociation enthalpy of the S-F bonds in SFs using the following data: D(S-S) = 226 kJ/mol; D(F-F) = 155 kJ/mol, x (S) = 2.58 and xº(F) = 3.98. a) 379 kJ/mol b) 188 kJ/mol c) 188 eV d) 379 kJ/mol e) 204 kJ/mol 4

Tramisol (shown below) is an anthelmintic used to control intestinal and lung worms in sheep and cattle. How many asymmetric centers are present in this structure? S ·N· N

Which molecule(s) has/have the shortest carbon-hydrogen bond(s)? II IV III

Which would you expect to have the highest melting point? I. CaO II. MgO Because 1. The internuclear distance is smaller, therefore the force is the stronger and requires more energy to overcome. II. The charge is higher, therefore interactions are stronger and require more energy to overcome. O II, II O I,I O I, II O II, I
