a You want to determine the value for the enthalpy of formation of CaSO4(s). Ca(s) + S(s) + 2 O₂ (g) → CaSO4(s) This reaction cannot be done directly. You know, however, that both calcium and sulfur react with oxygen to produce oxides in reactions that can be studied calorimetrically. You also know that the basic oxide CaO reacts with the acidic oxide SO3 (g) to produce CaSO4(s) with A₁ H° = -402.7 kJ. Outline a method for determining A₁H˚ for CaSO4(s), and identify the information that must be collected by experiment. Using enthalpy of formation data, confirm that AƒH° for CaSO4(s) = −1433.5 kJ/mol. What compound is formed when Ca and O2 react?
