Question

Which is true about water molecules?

A. Water molecules are polar, meaning they have partial negative and positive charges.

B. Water molecules are polar, meaning they have a net partial negative charge.

C. Water molecules are nonpolar, meaning they do not interact with each other.

D. Water molecules are nonpolar, meaning their charges balance each other out.

Answer 1

A. Water molecules are polar, meaning they have partial negative and positive charges.

Step-by-step explanation:

Water molecules are made up of two hydrogen atoms bonded to an oxygen atom. Because oxygen is more electronegative than hydrogen, the electrons in the covalent bond between the hydrogen and oxygen atoms are shared unequally.

This means that the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges. The resulting molecule has a bent shape and is said to be polar, with a positive end and a negative end.
