WebApr 10, 2024 · Solved Example. Suppose we want to calculate the heat of hydration for sodium sulfate decahydrate, Na 2 SO 4 ·10H 2 O. The enthalpy change of solution for the hydrated salt is -82.8 kJ/mol, and the enthalpy change of lattice energy for the anhydrous salt (Na 2 SO 4) is 1,060 kJ/mol.. Solution: To calculate the heat of hydration, we first … WebExamples of endothermic reactions: Photosynthesis: As a tree grows, it absorbs energy from the environment to break apart CO2 and H2O. Evaporation: Sweating cools a person down as water draws heat to change into gas form. Cooking an egg: Energy is absorbed from the pan to cook the egg. Examples of exothermic reactions:
