In which pair(s) would boiling occur? (Each pair corresponds to one row of the table)

a. 760 {mm,Hg} 700 {mm, Hg}
b. 480 {torr} 480 {mm, Hg}
c. 1.20 {atm} 912 {mm, Hg}
d. 1020{mm,Hg} 760 {mm, Hg}
e. 740 {torr} 1.00 {atm}

Aaron, I don't have the foggiest idea of what you are asking nor what the data shows.

I have to figure out which Atmospheric Pressure and Vapour Pressure pairs would cause boiling.

OK. Do you know the definition of boiling point? When the vapor pressure of the material is atmospheric pressure, the material will boil(is boiling). So
atm = 760 and vp 700, no boiling.
480 torr and 480 mm, boiling.
etc.
Don't forget to compare the same units.
