. Which molecule has the largest overall dipole?

HF

Explanation:

HF has the largest dipole moment, you can tell which molecule has the largest by looking on the periodic table, they are usually the pair that are furthest from each other and it is also due to them having the biggest difference in electronegativity, usually the closer two elements are, the weaker the dipole moment.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
