  • Fe=+2

    S=+6

    O=-2

    The Iron(II) tell you Fe is +2, O is always -2 except in peroxides and if O is -2 and there’s 4 of them, that’s a total of -8 and Fe is +2 so -8+2=-6 but since there’s no charge on the molecule, S must be +6 to cancel out the -6 charge.

  • +3

  • +2 because the ion so4^2-, Sulphur has +6and oxygen has – 2 so you get fe as +2

  • zero

  • H
