N2 molecules absorb ultraviolet light but not visible light. I2 molecules absorb both visible and ultraviolet light. Which of the following statements explains the observations?
More energy is required to make N2 molecules vibrate than is required to make I2 molecules vibrate.
More energy is required to remove an electron from an I2 molecule than is required to remove an electron from a N2 molecule.
Visible light does not produce transitions between electronic energy levels in the N2 molecule but does produce transitions in the
I2 molecule.
The molecular mass of I2 is greater than the molecular mass of N2 .

To make Au stronger and harder, it is often alloyed with other metals, such as Cu and Ag. Consider two alloys, one of Au and Cu and one of Au and Ag, each with the same mole fraction of Au. If the Au/Cu alloy is harder than the Au/Ag alloy, then which of the following is the best explanation based on the information in the table above?
Cu has two common oxidation states, but Ag has only one.
Cu has a higher melting point than Au has, but Ag has a lower melting point than Au has.
Cu atoms are smaller than Ag atoms, thus they interfere more with the displacement of atoms in the alloy.
Cu atoms are less polarizable than are Au or Ag atoms, thus Cu has weaker interparticle forces.

The photoelectron spectra above show the energy required to remove a 1s electron from a nitrogen atom and from an oxygen atom. Which of the following statements best accounts for the peak in the upper spectrum being to the right of the peak in the lower spectrum?
Nitrogen atoms have a half-filled p subshell.
There are more electron-electron repulsions in oxygen atoms than in nitrogen atoms.
Electrons in the p subshell of oxygen atoms provide more shielding than electrons in the p subshell of nitrogen atoms.
Nitrogen atoms have a smaller nuclear charge than oxygen atoms.

Nonane and 2,3,4-trifluoropentane have almost identical molar masses, but nonane has a significantly higher boiling point. Which of the following statements best helps explain this observation?
The C–F bond is easier to break than the C–H bond.
The C–F bond is more polar than the C–H bond.
The carbon chains are longer in nonane than they are in 2,3,4- trifluoropentane.
The carbon chains are farther apart in a sample of nonane than they are in 2,3,4-trifluoropentane.
