Question

a water molecule has: a one polar covalent bond and one nonpolar covalent bonds b two ionic bonds c two polar covalent bonds d two nonpolar covalent bonds

Explanation:

A water molecule ($H_2O$) consists of two hydrogen - oxygen bonds. Oxygen is more electronegative than hydrogen. In a covalent bond between oxygen and hydrogen, the shared electrons are pulled closer to the oxygen atom, creating a polar covalent bond. So, a water molecule has two polar covalent bonds.

Answer:

C. two polar covalent bonds
