How does the nonpolar character of oil molecules helps when removing oil from water using nets and floating barriers?
Have you never used a separating funnel?
The less dense (typically organic) phase lies atop an aqueous phase in which it is immiscible. The long chain oil molecules, whose principle intermolecular attraction is the dispersion force, cannot be effectively solvated by water.
Crude oil is typically slightly less dense than water, and it should float on water in the event of an oil spill.
Just as an aside, I once had a

The nonpolar character of oil molecules allows them to adhere to other nonpolar substances, such as the material used in nets and floating barriers. When oil comes into contact with these materials, the nonpolar oil molecules stick to the nonpolar surface of the nets or barriers, effectively removing the oil from the water. This property is due to the principle that "like dissolves like," where nonpolar substances tend to dissolve or adhere to other nonpolar substances more readily than polar substances.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
