Calculate the standard free-energy change(kJ) for the reaction at 25°C Use the standard reduction potentials from the appendix in the book. Please give your answer in standard notation and round to three significant figures. Give only the numeric value assuming a measure of kJ 2+ 3+ 2Au³+ (aq) + 3Mg(s) → 2Au(s) + 3Mg²+ (aq)
