Can someoneice cubes float in a glass of water a. liquid water is less dense than the ice cubes. b. the molecules of ice are arranged in an orderly way so there is an unusually large amount of empty space in the ice cubes. c. the ice is losing mass through the melting process. d. the colder ice is more dense.

The answer is b, because solid water is less dense than liquid water and that is why it floats. This property of water is due to hydrogen bonds between the water molecules because in ice, the regular pattern of hydrogen bonds pushes the molecules further apart leaving a lot of empty space between the water molecules. 

And a) oxygen i believe

Ibelieve it's celsius. hope this .
