2. We add 4.158 kJ of heat to a calorimeter that contains 55.0 g of water. The temperature of the water and the calorimeter, originally at 22.34°C, increases to 38.74°C. Calculate the heat capacity of the calorimeter in /°C. The specific heat of water is 4.184 J/g °C. 3. What is the standard enthalpy change for the following reaction? N2H (1) + 2NO2(g) → 2N2O(g) + 2H2O(1) AH (kJ/mol) N2H4(1) +50.6 NO2(g) +33.1 N2O(g) +82.1 H20(1) -285.8

7. A 2.053-g sample of ethylene glycol, CH.02 (62.07 g/mol) was burned in a bomb calorimeter with excess oxygen. The temperature of the calorimeter and the water before combustion was 16.49 °C; after combustion the calorimeter and the water had a temperature of 23.12 °C. The calorimeter had a heat capacity of 567 J/K, and contained 1.316 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of ethylene glycol.
