Twо mоlecules оf wаter аre diаgrammed above. The dashed line between the two water molecules represents a(n) [d], which is a weak attraction between the two molecules. This attraction occurs because the hydrogen atom has [c] and the oxygen atom has [b] as a result of oxygen and hydrogen atoms being joined by a(n) [a] (represented by a solid line in the diagram) to form a water molecule.
