1 Ethylene glycol, used as a coolant in automotive engines, has a specific heat capacity of 2.42 Jig K). Calculate q when 3 65 kg of ethylene glycol is cooled from 132C to 85C. (5 points) A. -1900 kJ B. 420 kJ C-99 kJ D. -0.42 kJ E. -4.2 * 10-6 kJ Calorimetry (15 points) 2. A student in Chem 210 carries out a neutralization reaction in her Styrofoam cup calorimeter that has a heat capacity of 78.3 JAC. She mixes 350 mL of 25 M HCl acid solution and 35.0 mL of 2.5 M KOH base solution at 17.9C (Assume the density is 1.05 g/mL and heat capacity of her solutions are 4.05 J/g C). The temperature after the mixture rose to 29.4 C. (3 pts each) a) Calculate the heat energy absorbed by the solution (soon). To b) Calculate the heat energy absorbed by the calorimeter (q calometer). -) A
