The dipole moments decrease across the series PH3 > AsH3 > SbH3 > BiH3. Why do the boiling points increase?

Check all that apply.

The electron clouds of the molecules become smaller along the series.

The electron clouds of the molecules become larger along the series.

The smaller numbers of electrons are more polarizable, leading to greater dispersion forces.

The larger numbers of electrons are more polarizable, leading to greater dispersion forces.

The electronegativities of the -C≡CH and -C≡N groups are the same, but the dipole moments of the CH3C≡CH and the CH3C≡N are 0.78 D and 3.92 D, respectively. Explain why the dipole moments are so different.

Estimate the dipole moments of all five possible HX compunds, where X is a halogen, using only the Pauling electronegativities and showing your answers in both Coulomb-meters and Debye. What is responsible for the trend in polarities of these bonds that your calculations predict? (i.e. what causes the differences in the halogen electronegativities?) Follow-up question: How does this trend differ from that of van der waals interactions involving the halogens?

Suppose that real interest rates decrease across Europe. This development will (Increase/Decrease) U.S. net capital outflow at all U.S. real interest rates, which in turn will cause the (Demand for/Supply of) loanable funds to (Increase/Decrease) because net capital outflow is a component of the relevant curve in the loanable funds market.

With the decrease in the nations deficit does this correlates into new jobs? Why do you think the economy deficit is decreasing? When the economy was bad there is enough blame to go around; should someone (or other) get credit for this decrease in the deficit?

Why do transportation costs initially decrease as the number of warehouses in a system increases?

1) Build models for the PH3 and PH4+ species. How do you compare the angles of H - P - H bonds in both species? If different, explain why. How do you compare your electronic and molecular geometries? 2 )Build the models for the PH3 and H2S species. How do you compare the binding angles in both species? If they are different, explain why. How do you compare your electronic and molecular geometries?
