    1. \(CO_2\)
    2. \(CHCl_3\)
    3. \(NH_3\)
    4. \(CCl_4\)

    Q2.

    The enthalpy of vaporization of liquid mercury is 59.11 kJ/mol. What quantity of energy as heat is required to vaporize 0.500 mL of mercury at 357 °C, its normal boiling point? (d= 13.6 g/mL).

    Q3.

    The mineral fluorite is composed of calcium and fluoride ions. The calcium ions are face centered cubic with fluoride ions filling holes. Draw the structure. Based on the chemical formula, would the tetrahedral or octahedral holes be filled?
