Dissolving

100

Cooking oil is a nonpolar substance. Name one other substance/molecule that would dissolve in it.

Ex: CO₂, H₂, hexane, heptane, F₂, or any other nonpolar molecule.

200

H₂O and CO₂ are mixed. Will they dissolve in each other? Why or why not?

No because water is polar and CO₂ is nonpolar. Like dissolves like and they are not the same polarity.

300

Why can't a nonpolar solute dissolve in a polar substance?

It's IMFs aren't strong enough to disrupt the IMFs between the polar molecules.
