Post Lecture Homework Chapter 06 9 of 13> but it is usually expressed per mole of reactant and with a sign opposite to that of q for the surroundings. The total internal energy change,AE (sometimes referred to as Î17), is the sum of heat, q, and work done, w: However, at constant volume (as with a bomb calorimeter) w = 0 and so Î E qu â¼ Part A A calorimeter contains 17.0 mL of water at 12.5 °C.When 1.60 g of X (a substance with a molar mass of 55.0 g/mol) is added, it dissolves via the reaction X(s) +H20(1)X(aq) and the temperature of the solution increases to 28.5 °C Calculate the enthalpy change, AH, for this reaction per mole of X Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/ (g·°C)], that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the surroundings. Express the change in enthalpy in kilojoules per mole to three significant figures View Available Hint(s) kJ/mol Submit X Incorrect: Try Again; 5 attempts remaining â¼ Part B Consider the reaction C12H22011 (s) 1202(g)-12CO2(g) 11H201) n which 10.0 g of sucrose, C12 H2011, was burned in a bomb calorimeter with a heat capacity of 7.50 kJ/ C. The temperature increase inside the calorimeter was found to be 22.0 ° C. Calculate the change in internal energy, Î E, for this reaction per mole of sucrose Express the change in internal energy in kilojoules per mole to three significant figures View Available Hint(s) kJ/mol Submit rovide Feedback Next >
