Question

what is the most important role of hydrogen bonding between water molecules?
o it enables water molecules to bond to each other.
o it allows oxygen and hydrogen atoms to be charged.
o it allows cells to keep water in balance.

Explanation:

Hydrogen - bonding between water molecules is a type of intermolecular force that enables water molecules to bond to each other. Oxygen and hydrogen atoms in water are already charged due to electronegativity differences, and while water - balance in cells is related to water properties, the most fundamental role of hydrogen - bonding is the intermolecular bonding of water molecules.

Answer:

It enables water molecules to bond to each other.
