A solid will float on any liquid that is more dense than it is. The volume of a piece of amber is 50.0 mL, and the mass is 54.0 g. On which of the following liquids will the calcite float: acetone (d= 0.292 g/mLl), water (0.998 g/mL), propane (d=1.26g/mL), methylene bromide (d=2.50 g/mL), bromine (d=3.10 g/mL), mercury (d=13.55 g/mL)

1) a. water molecule breaks up into hydrogen and oxygen on passing electricity. does this involve breaking intermolecular or intramolecular forces of attraction. explain b. on boiling water changes to water vapor. does this involve breaking intermolecular or intramolecular forces of attraction. explain methanol evaporates faster than water. contrast the intermolecular forces and the vapor pressures of methanol and water?
