In a calorimetry experiment, the following reaction was studied: 2NaOH(aq) + H2SO4(aq) Na2SO4(aq) + 2H2O(l) 100.0 mL portions of 1.00 M NaOH and H2SO4, at 24°C, were mixed. The maximum temperature achieved was 30.6°C. Neglecting the heat capacity of the coffee–cup calorimeter, and assuming that the products has a density of 1.0 g/mL and a heat capacity of 4.184 Jg-1K–1, calculate a. the heat released in the reaction, in J. b. Hrxn, in kJ/mol of Na2SO4 produced

100.0 mL of 0.400 M aqueous NaOH and 50.00 mL of 0.400 M aqueous H2SO4, each at 24.00°C, were mixed, see equation: 2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l) The final temperature achieved by the solution was 26.65 °C. Neglect the heat capacity of the cup and the thermometer, and assume that the solution of products has a density of exactly 1.00 g/mL and specific heat capacity of 4.18 J/(g•C) How much heat did the reaction release?
