Answer:
Pentafluorobenzene: 11,92 min
Benzene: 12,14 min
Explanation:
<em>Retention time of pentafluorobenzene is 12,98 min and 13,20 min of benzene.</em>
The adjusted retention time is the time an analyte spends in the column not the stationary phase. As time of unretained solute is 1,06 min the adjusted retention time for an analyte is:
tr' = tr - 1,06min
For pentafluorobenzene:
tr' = 12,98min - 1,06min = <em>11,92 min</em>
For benzene:
tr' = 13,20 - 1,06min = <em>12,14 min</em>

Explanation:
Octane is composed of carbon and hydrogen atoms.
The elephant has more inertia than the dog so it takes more force to change the motion of the elephant.
The entropy will increase in pressure if you increase the pressure on the system the volume decrease the energies of the particles are in a smaller space so they are less spread out
