Question

How does the nonpolar character of oil molecules help when removing oil from water using nets and floating barriers?

Answer 1

A polar molecule has its electrostatic potential conveyed unevenly all through the molecule. The subsequent distinction in electric potential is known as a dipole moment. A water molecule comprises two hydrogen atoms attached to an oxygen atom.

Complete step by step answer:
The less thick (normally natural) phase lies on an aqueous phase in which it is immiscible. The long-chain oil atoms, whose rule intermolecular attraction is the scattering force, can't be effectively solvated by water.
Crude oil is normally marginally less thick than water, and it should float on water in case of an oil spill.
Similarly, as an aside, I once had a 500⋅mL sep jar with a plastic stopcock that had never been utilized for chemicals, and utilized it for the express reason to make the gravy when I was cooking a meal - for example, drain the fat and cooking juices into a sep pipe, and the juice from the meat would gather in the base half, which obviously you could deplete off to a separate skillet to make the gravy.

Note: 1)The distinction in electronegativities among oxygen and hydrogen atoms makes fractional negative and positive charges, separately, on the atoms.
2)Water molecules draw in or are pulled in to other polar molecules.
3)Molecules that don't dissolve in water are known as hydrophobic (water-dreading) molecules
4)For different liquids, solidification when the temperature drops incorporates the bringing down of kinetic energy, which permits molecules to pack more firmly and makes the strong denser than its fluid form.
