Question

Part 1

CaSO4⋅2 H2O (s) can be heated to completely drive off water to form CaSO4 (s). A 2.49 g sample of CaSO4⋅2 H2O (s) is heated until the mass is constant. Calculate the mass of the solid that remains after the dehydration reaction is complete. (see picture)

Part 2

The equation for the overall process of extracting Al from Al 2O3 ore is shown below.
Al2O3 (s)→2Al(s)+3/2 O2 (g) ΔH ̊ = 1675 kJ/molrxn
How much energy is saved when recycling Al vs. extracting Al from Al2O3? Justify your answer.

3. Consider heating the hydrate CaSO, 2 H,0 (s) to form the anhydrous salt, CasO, (s). CaSO, 2 H,0 (s) 2 CaSO, (s) + 2 H,O (g) Substance CaSO, 2 H2O (s) CaSO, (s) H2O (g) AG` (kJ/mol) -1795.70 -1320.30 -228.59
