A 100.0 ml sample of 1.00 M NaOH is mixed with 50.0 ml of 1.00 M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. the temperature of each solution before mixing is 22.5°C. After adding the NaOH solution to the coffee cup and stirring the mixed solutions with thermometer; the maximum temperature measured is 32.1 C. Assume that the density of the mixed solutions is 1.00 g/ml that the specific heat of the mixed solutions is 4.18 J/(g•°C), and that no heat is lost to the surroundings. a) Write a balanced chemical equation for the reaction that takes place in the Styrofoam cup. b) Calculate the enthalpy change per mole of H2SO4 in the reaction
