Elemental phosphorus exists in a few different allotropes, two of which are listed below. White phosphorus: a molecular substance with the formula P4. Black phosphorus: an extended network of phosphorus atoms connected by covalent bonds. Which of these two allotropes would you expect to have the higher melting point and why? White phosphorus, because the strongest interaction broken while melting is LDFs, which require more energy to overcome. White phosphorus, because the strongest interaction broken while melting is covalent bonds, which require more energy to overcome. Black phosphorus, because the strongest interaction broken while melting is LDFs, which require more energy to overcome. Black phosphorus, because the strongest interaction broken while melting is covalent bonds, which require more energy to overcome. O Not enough information is given in order to determine relative melting points.

Prior to the discovery that freon-12 (CF2Cl2) was harmful to the Earth's ozone layer, it was frequently used as the dispersing agent in spray cans for hair spray, etc. Its enthalpy of vaporization at its normal boiling point of -29.2 degree C is 20.25 kJ/mol. Estimate the pressure that a can of hair spray using freon-12 had to withstand at 40 degree C, the temperature of a can that has standing in sunlight.
