    Fill in the Blanks Let's use calorimetry to measure heats of reaction. Suppose you mix 25.0 mL of 0.08M cesium hydroxide with 25.0 mL of 0.08M hydrochloric acid. Assume both solutions are at 28.0°C. The temperature of the solution after the reaction is 30.2°C. Because the temperature of the solution went up, the reaction is (endothermic/exothermic). Now compute the heat of the reaction assuming the heat capacities of the solutions are equal to pure water (4.18 J/g°C). Report the Q...
