Tutored Practice Problem 10.4.5 COUNTS TOWARDS GRADE Use constant-volume calorimetry to determine energy change. Close Problem A 1.04-g sample of glutaric acid (CH3O4) is burned in a bomb calorimeter and the temperature increases from 26.00 °C to 28.90 °C. The calorimeter contains 1.13x103 g of water and the bomb has a heat capacity of 872 J/°C. Based on this experiment, calculate AE for the combustion reaction per mole of glutaric acid burned (kJ/mol) ΔΕ - kJ/mol CHO4(s)5 02(g)5 CO2(g)+4 H20(1...
