Question

what is responsible for ice floating in liquid water?
a waters hydrogen bonding
b the shape of a water molecule
c the density of ice
d all of the above

Explanation:

Water's hydrogen - bonding causes water molecules to form an open - lattice structure in ice, which is related to the shape of water molecules. This open - lattice structure makes ice less dense than liquid water, allowing ice to float. So all the factors mentioned contribute.

Answer:

d. all of the above
