The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. Thermometer Cardboard or In the laboratory a general chemistry student finds that when 14.72 g of BaBr2(s) are Styrofoam lid dissolved in 101.00 g of water, the temperature of the solution increases from 22.80 to 25.27 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.82 J/°C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of BaBr2(s) in kJ/mol. Reaction occurs in solution.

32. It would be very useful if we could use the inexpensive carbon in coal to make more complex organic molecules such gaseous or liquid fuels. The formation of methane from coal and water is reactant-favored and thus cannot occur there is some energy transfer from outside. This problem examines the feasibility of other reactions using coal and water. a) Write three balanced equations for the reactions of coal (carbon) and steam to make ethane gas, C,H,(g), propase gas, C,H,(g), and liquid methanol, CH,OH(C), with carbon dioxide as a by-product. b) Using the data in Appendix B, calculate AH, AS", and AG° for each reaction, and then comment on whether any f them would be a feasible way to make the stated products.
