Cân bằng

Fe(OH)2+H2SO4 đặc nóng ----->Fe2(SO4)3+SO2+H2O
Cu2O+HNO3---->Cu(NO3)2+NH4NO3+H2O
FexOy+H2SO4---->Fe2(SO4)3+SO2+H2O
FexOy+HNO3---->Fe(NO3)2+NO2+H2O
FexOy+NO3---->Fe(NO3)3+NtOz+H2O
2Fe(OH)2 + 4H2SO4 ---> Fe2(SO4)3 + SO2 + 6H2O
4Cu2O + 18HNO3 ---> 8Cu(NO3)2 + NH4NO3 + 7H2O
4FexOy + (12x-4y) H2SO4 ---> 2x Fe2(SO4)3 + (6x-4y) SO2 + (12x-4y) H2O
FexOy + (4x-2y) HNO3 ---> x Fe(NO3)2 + (2x-2y) NO2 + (2x-y) H2O
(5t-2z) FexOy + (18xt - 2yt - 6xz) HNO3---> (5tx-2zx) Fe(NO3)3 + (3x-2y) NtOz + (9xt-yt-3xz) H2O
Xong rồi đó! :)
