Question

the bond holding two water molecules together is a(n) blank bond.

Explanation:

Water molecules are held together by hydrogen bonds. A hydrogen - bond is a type of intermolecular force that occurs when a hydrogen atom covalently bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) is attracted to another electronegative atom in a neighboring molecule. In water, the oxygen atom is highly electronegative and the hydrogen atoms are attracted to the oxygen atoms of other water molecules.
