18. (WCSU25.[x]) Ice cream begins as a solution of milk, sugar, and stabilizers. This liquid mixture is pasteurized at high temperature (72 oC) to kill any harmful bacteria. The pasteurized solution is cooled, flavors are added, and then it is placed in a “hardening room” (at -38 oC) to freeze. Cs (solid) = 3.10 J/g·K Cs (liquid) = 1.60 J/g·K ΔHfus = 186 J/g a. (5 points) Draw the cooling curve for ice cream beginning as a liquid at 72 oC to solid at -38 oC. The freezing point of ice cream is -3 oC. Label the axes with temperature values. (Blank graph given below.)) b. (8 points) Calculate how much heat (in kJ) must be removed from a ½ gallon (912 g) of Bittersweet Mint when it cools from 72 oC to -38 oC. Enter the heat lost from the ice cream below:

24. (WCSU25.[x]) Strategies to convert methane to methanol may be useful to produce quantities of methanol for use as a fuel alternative to gasoline. a. (4 points) Write a chemical equation where ΔHf = ΔHrxn for the formation of methanol (CH3OH) b. (4 points) If the heat of formation of 1 mol of CH3OH is -201.3 kJ, calculate the heat exchanged when 43 g are formed? Enter the heat calculated in part b below.
