Q1) Para-dichlorobenzene has melting point 53.0 ^oC with heat of fusion H_fus = 98.6 J/g. The specific heat of the solid is 1.129 J/g^oC. How much heat energy (as KJ, kilojoules) will it take to heat a 50.00 g sample of para-dichlorobenzene from 25.0 ^oC to the melting point, and then melt ALL of it? (Hint: a two-step process.)

Report your answer as KJ to three significant digits. Do not show the unit in your answer.

Q2) Which of the following physical or structural characteristics of a compound tend to make it more polararizable? More than one answer may be correct.

		More electrons in the molecule
		More electronegative atoms in the structure
		Smaller diameter atoms in the stucture.
		Heavier atoms in the structure
		Many atoms in the structure
