Answer #2
Na+ and NO3- = Na3NOFe2+ and O2- = FeONa+ and (SO4)2- = Na2SO4Fe2+ and NO3- = Fe3(NO)2Na+ and (AsO4)3- = Na3AsO4Fe2+ and(SO4)2+ = Fe(SO4)Fe2+ and(AsO4)3- = Fe3(AsO4)2
Ca2+ and O2- = CaOAl3+ and O2- = Al2O3Ca2+ and NO3- = Ca3(NO)2Al3+ and NO3- = AlNOCa2+ and(SO4)2+ = Ca(SO4)Al3+ and(SO4)2+ = Al2(SO4)3Ca2+ and(AsO4)3- = Ca3(AsO4)2Al3+ and(AsO4)3- = Al(AsO4)
