Calculate the heat of hydration of magnesium sulfate (MgSO4) given that 4.17 g of MgSO4 is dissolved in 50.0 ml of water at 25°C, and the resulting solution cools from 25°C to 20°C. The specific heat capacity of the solution is 4.18 J/(g·°C), and the density of the solution is 1.00 g/ml. Don't forget to include the units in your final answer.

A chemistry student needs to determine the enthalpy of desorption for a specific substance. The substance was adsorbed onto activated carbon in a packed bed reactor at 25°C and under a pressure of 4 bar. The adsorption process was carried out until saturation was reached. The packed bed reactor was then heated to 100°C until complete desorption. The pressure was maintained at 4 bar during the entire process. Given the initial mass of the adsorbate and the final mass of the activated carbon, calculate the enthalpy of desorption for the substance.
