In a calorimetry experiment, a salt is dissolved in water within an insulating container. The temperature of the solution (surroundings) decreases from 25°C to 14°C. Given that the mass of the solution is 120 g, and the specific heat of the solution is 3.18 J/g°C, calculate the enthalpy change (in kJ) for the dissolving process. Be sure to give the correct sign for your answer, and identify the dissolving process as endothermic or exothermic. Group of answer choices
