A 2.200 g sample of quinone (C6H4O2) is burned in a bomb calorimeter (constant volume calorimeter) whose heat capacity is 7.854 kJ/C. The temperature of the calorimeter increases from 23.44C to 30.57C. What is E for the reactionC6H4O2 (l) + 6O2 (g) 6 CO2(g) + 2H2O(l)E = qv = -CvT2. Calculate the standard reaction enthalpy, H, for the reaction:C6H4O2 (l) + 6O2 (g) 6 CO2(g) + 2H2O(l)Substance HfC6H4O2 (l) -185.7 kJ/molCO2(g) -393.5 kJ/molH2O(l) -285.8 kJ/mol3. Write the formation reaction for AlCl3(s). Include the phase of all the reactants and products.Supplemental Instruction1060 Hixson-Lied Student Success Center v 294-6624 v www.si.iastate.edu4.
