Which statements accurately describe the polarity and electronegativity of water?

Strong covalent bonds are formed between two or more water molecules.

Water molecules are polar and thus associate with each other through hydrogen bonds.

Water is polar, which means that it has an overall negative charge.

The oxygen atom in a water molecule is strongly electronegative.

Covalent bonds in a water molecule bind its oxygen atom to its two hydrogen atoms.

Why does oil not dissolve in water?

Water molecules form hydrogen bonds with each other and exclude oil molecules.

Hydrogen bonds form between oil molecules, causing them to aggregate.

Water molecules form stronger associations with other polar molecules than with oil.

Oil is less dense than water, which causes it to separate from water instead of dissolving.
