How to balance FeSO4+ H2O + O2- Fe2(SO4)3+ Fe (OH)3? Please ask for detailed steps Thank you How to balance FeSO4+H2O+O2-Fe2(SO4)3+Fe (OH)3(OH)3, ask for detailed steps Thank you

Normalization method: Let the coefficient of the most complex compound Fe2(SO4)3 be 1, according to the conservation of sulfur element, the FeSO4 is 3, according to the conservation of iron element, the Fe (OH)3 is 1, according to the conservation of hydrogen element, the H2O is 3/2, according to the conservation of oxygen element, the O2 is 3/4, and finally the coefficient is simplified to integer to get 12FeSO4+6H2O+3O2=4Fe2(SO4)3+4Fe (OH)3
