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:

Hydrogen - bonding in water causes ice to form an open - lattice structure. The shape of the water molecule affects the way hydrogen bonds form. This open - lattice structure makes ice less dense than liquid water, allowing it to float. So all factors contribute.

Answer:

d. all of the above
