Why is it important that hydrogen ions in two different water molecules would be attracted to one another or that the oxygen atoms in two water molecules would repel one another?
A) hydrogen atoms have a partial negative charge, and will be attracted to one another.
B) the slightly positive hydrogen of one molecule is attracted to the slightly negative oxygen of another molecule.
C) hydrogen is more electronegative than oxygen, and the electrons spend more time closer to the oxygen atom.
D) its tow hydrogen atoms are joined to the oxygen atom by single covalent bonds.
Answer: B) the slightly positive hydrogen of one molecule is attracted to the slightly negative oxygen of another molecule.
