4. At high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why?
It is much greater because real gas particles take up space.
There is no difference because the gas laws are always obeyed.
It is much less because real gas particles are not moving.
It is much less because at high pressures the temperature drops.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
