Question

the diagram shows hydrogen bonds between water molecules. label the diagram to show how hydrogen bonds form. a label may be used once, twice, or not at all.

Explanation:

Hydrogen bonds form between the slightly - positive hydrogen atom of one water molecule and the slightly - negative oxygen atom of another water molecule. In a water molecule (H₂O), oxygen is more electronegative than hydrogen, creating a polar molecule. The hydrogen atoms have a partial positive charge and the oxygen atom has a partial negative charge.

Answer:

The hydrogen atoms (H) should be placed near the oxygen atoms (O) to show the hydrogen - bonding interaction. The hydrogen bond is an intermolecular force between the H of one water molecule and the O of another water molecule. So, place the H labels near the O atoms of neighboring water molecules to indicate the hydrogen - bond formation.
