What mass of CCl2F2 substance must evaporate in order to freeze 109 of water initially at 24 degrees celsius? (The heat of fusion of water is 334 J/g the specific heat of water is 4.18 J/gK .)
HFC's (hydrofluorocarbons) are replacing CFC's (chlorofluorocarbons) because the C-H and C-F bonds are stronger than C-Cl bonds. If the bond enthalpy of a C-F bond is 482 kJ/mol.
