(a) The melting point of NaCI was found to be 801 °C. Suggest, with reasons, whether the melting point of MgO will be higher or lower than that of NaCl. (Refer to Section 1.2.2, pg 4 of Topic 3 Lecture Notes to revise how to compare ionic bond strength) (b) The boiling points of ammonia, carbon monoxide and carbon dioxide are given in the table below: gas formula M, b.p./°C ammonia NH3 17 -33 carbon monoxide CO 28 192 - carbon dioxide CO2 44 -78 With reference to their structure and bonding, account for their boiling points. (Refer to Section 5, pg 22 of Topic 3 Lecture Notes to revise how to identify the type of IMF)

Freon-12 (CF2Cl2), widely used as a refrigerant and aerosol propellant, is a dangerous airpollutant. In the troposphere, it traps heat 25 times as effectively as CO2, and in thestratosphere, it participates in the breakdown of ozone. Freon-12 is prepared industrially byreaction of gaseous carbon tetrachloride with hydrogen fluoride. Hydrogen chloride gasalso forms. How many grams of carbon tetrachloride are required for the production of16.0 dm3 of Freon-12 at 27°C and 1.20 atm?
