CCl4; molar mass = 153.82 g/mol
PF5; molar mass = 125.966 g/mol

Why do the ice cubes float on liquid water?
Due to the "open structure" of the arrangement of water molecules when cooled.
Due to the "extensive structure" of the arrangement of water molecules when cooled.
Due to the "open structure" of the arrangement of air when water is cooled.
H2O and NH3 are polar molecules that can form the strongest type of intermolecular force (hydrogen bonding). However, the boiling point of H2O is 100.00 °C whereas NH3 is -33.34 °C.
Why is that so?
H2O can form more hydrogen bonds than NH3
H2O can form less hydrogen bonds than NH3
O on the H2O is more electronegative than N on the NH3
