a) False because all gases have the same average kinetic energy at the same temperature.
b) False because the gases will have the same partial pressures due to the fact that we have the same number of moles of each.
c) False because the average velocity of the B molecules will be less than that of the A molecules because the B molecules are heavier.
d) True because B molecules are heavier, which means they will contribute more to the density.
