Final answer:
A single water molecule typically forms up to two hydrogen bonds with other water molecules, not four, by using its hydrogen atoms.
Step-by-step explanation:
The statement that a single water molecule can form up to four hydrogen bonds with other water molecules at the same time is false. A single water molecule can actually form up to four hydrogen bonds, but it typically forms up to two hydrogen bonds with other water molecules, as it has two hydrogen atoms that can each form a hydrogen bond with the oxygen atom of another water molecule. The additional capacity for hydrogen bonding comes from the lone pairs of electrons on the oxygen, which can also form hydrogen bonds with the hydrogen atoms of other water molecules.
