    A. Hydrogen bonding. B. Formation of covalent bonds between water molecules. C. the energy change when water freezes. D. the lower entropy of the solid.

    It would be due to the hydrogen bonding

    I'm pretty sure that the energy change when water freezes would not have any affect on the density

    \[\Delta S \] probably wouldn't affect the density either..

    Its due to hydrogen bonding dominating the intermolecular forces, which results in a packing of molecules less compact in the solid.

    ok here is explanation: "A water exhibits hydrogen bonding between molecules. when water begins to freeze a crystal structure is formed using those h bonds, in this crystal structure there are large empty spaces that make the density less".

    like I chose A because the others made no sense

    as water freezes (l)-->(s).. hydrogen bonding ceases?

    Formation of covalent bonds makes no sense because that implies that there aren't any in water, and there are, H bonding is a type of covalent bonding.

    hydrogen bonds causes molecules to push farther apart, which lowers the density.

    whats the confusion ?

    ok I see. since they are farther apart, density is less. that makes sense.

    the molecules have less energy and hydrogen bonding takes over. The molecules form a ordered crystal through hydrogen bonding that spaces the molecules farther apart than when they were in a liquid. This makes ice less dense than water
