1.Determine AH° for 2 Al (s) + 3/2 02 (g) → Al203 (s) Given AH° = -286 kJ/mol AH° = -1050 kJ/mol AH° = -238 kJ/mol H2 (g) + ½ 02 (g) → H2O (I) 2 Al (s) + 6 H+ (ag) → 2 Al3+ (ag) + 3 H2 (g) Al203 (s) + 6 H+ (ag) → 2 Al3+ (ag) + 3 H20 (g) 2. Assume a coffee-cup calorimeter had a heat capacity (C) of 420 J/°C. If 1.00 g of Al203 completely reacted with HCI (H+ ) in the calorimeter, calculate the temperature change, AT. Hint: one of the reactions and AH values from question #1 may be helpful. Watch your units! MW (Al203) = 101.96 g/mol
