Given 307.5 g of hot tea at 73.5 °C, what mass of ice at 0 °C must be added to obtain iced tea at 12.5 °C? The specific heat of the tea is 4.18 J/(g·°C), and ΔHfusion for ice is +6.01 kJ/mol.

Determine the amount of heat (in kJ) required to vaporize 25 mL of mercury at its boiling point. For mercury, ΔHvap = 56.9 kJ/mol (at 357 °C). The density of mercury is 13.6 g/mL.

Determine whether the process of dry ice evaporating is endothermic or exothermic and indicate the sign of ΔH.

Which of the following processes for ethanol (C2H5OH) is endothermic?

Ethyl chloride (C2H5Cl), a substance used as a topical anesthetic, is prepared by reaction of ethylene with hydrogen chloride: C2H4(g) + HCl(g) → C2H5Cl(g) ΔH° = -72.3 kJ. What is the value of ΔE (in kilojoules) for the reaction, assuming no work is done other than pressure-volume work?
