Unformatted text preview: c. (8) Write the set of combustion reactions that sum to the above as the net reaction. (Show phases). d. (7) Calculate the standard heat of reaction of the above reaction from the tabulated heats of combustion. ECH 3023 Practice Exam 5 Fall 2006 4. (30 pts.) 2 mol % aqueous HCl (aq) at 25 o C is neutralized with 2 mol% NaOH (aq) at 25 o C. a. (15) Estimate the heat removed per mole NaCl (aq) formed to keep the neutralized solution at 25 o C. Assume the heat of solution of NaCl(c) is +3.5 kJ/mol. b. (15) Calculate the final temperature of the mixed solution if the solutions are combined adiabatically. Assume a constant heat capacity of 4.0 kJ/kg-K for the mixture....
