Question

Which of the following is the chief factor leading to why the density of ice less than the density of water?

Answer 1

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.

Answer 2

It would be due to the hydrogen bonding

Answer 3

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

Answer 4

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

Answer 5

Tara I think i agree with you

Answer 6

I agree tooo !!!!!!!!!

Answer 7

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

Answer 8

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".

Answer 9

like I chose A because the others made no sense

Answer 10

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

Answer 11

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.

Answer 12

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

Answer 13

whats the confusion ?

Answer 14

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

Answer 15

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
