Question

what is the most important role of hydrogen bonding between water molecules? it enables water molecules to bond to each other. it allows oxygen and hydrogen atoms to be charged. 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 not because of hydrogen - bonding. While water balance in cells is important, the most fundamental role of hydrogen - bonding in water is the intermolecular bonding between water molecules themselves.

Answer:

It enables water molecules to bond to each other.
