Answer» Ferrous sulfate is FeSO4•nH2O, where n is 1, 4, 5, 6 or 7. Since 1, 5 and 6 are rare, I will use n = 7. Then,Mg + FeSO4•7H2O = MgSO4•7H2O + FeChange in FREE Energy: ΔG(20C) = -361.5kJ (NEGATIVE, so the REACTION runs)Change in Enthalpy: ΔH(20C) = -374.1kJ (negative, so the reaction is exothermic)NOTE: MgSO4•7H2O is COMMONLY called Epsom salt.Hope your doubt is clear plz mark as brainliest
