Question
1. A student mixed 50.0 mL of HCr (aq) and 75.0 mL of NaOH (aq) in a calorimeter. Each of the reactant solutions had a density of 1.04 g mL and an initial temperature of 22.6 °C. After HCI (aq) and NaOH (aq) reacted, the mixed solution reached a maximum temperature of 26.3 °C. Calculate the heat released or absorbed by the reaction process in unit J. Assume the product solution has C, = 4.18 Jg -1 °C-1. Is the reaction exothermic or endothermic? Explain your answer. %3D
