Carbon tetrachloride, ccl4, was once used as a dry cleaning solvent, but is no longer used because it is carcinogenic. at 55.8°c, the vapor pressure of ccl4 is 52.7 kpa, and its enthalpy of vaporization is 29.82 kj/mol. use this information to estimate the normal boiling point (in °c) for ccl4.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
