For the reaction Fe2O3 (s) + 3 CO (g) → 2 Fe (s) + 3 CO2 (s)
ΔG° = -31. kJ. Calculate the standard free energy of formation of the ferric oxide, Fe2O3, if ΔG°f of CO = -137 kJ/mol and ΔG°f of CO2 = -394 kJ/mol.
Julie is conducting an experiment where she placed 30.0 mL of water in a calorimeter at 10.0 °C. Then, 2.5 g of A (molar mass = 48.0 g/mol), also at 10.0°C, is added to the water in the calorimeter and the temperature of the solution increases to ..
