Answer to Question #55344 in General Chemistry for Vladimir

Question

Julie is conducting an experiment where she placed 30.0 mL of water in a calorimeter at 10.0 °C. Then, 2.5 g of A (molar mass = 48.0 g/mol), also at 10.0°C, is added to the water in the calorimeter and the temperature of the solution increases to 29.0 °C. The following reaction is produced:
a.) What is the enthalpy of the reaction (ΔH°rxn), in kJ/mol?
