Cr5+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Pb4+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Sn2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Mn2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Ag+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
H+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-

  • chemistry -

    The electrical charge on ALL compounds is zero; therefore, you write enough + ions and - ions to make th compound zero. For example,
    LiBr, Li2O, LiCN, Li2SO3, Li3PO3, LiMnO4
    Cu occurs as both +1 ad +2; therefore, Cu can't be done without more information.
    Mn would be
    MnBr2, MnO2, Mn(CN)2, MnSO3, Mn3(PO3)2.
    You do the other s the same way.
