1.Elements following by oxidation numbers
- v1:a)K(+1),C(+3),O(-2);b)B(+3),Cl(-1);c)N(+4),O(-2)
- v2:a)Mg(+2),C(+3),O(-2);b)P(+5)F(-1);c)N(+5),O(-2)
2.
- v1:MnO2(OA),Cu(s)(RA),Cu+(OA),Mn2+(RA)
MnO2 => Mn 2+ reduction L to R, oxidation R to L
Cu(s) => Cu+ oxidation L to R reduction R to L
- v2Cu+(OA),Mn2+(RA),MnO2(OA),Cu(s)(RA)
Cu+=>Cu(s) reduction L to R, oxidation R to L
Mn2+=>MnO2 oxidation L to R, reduction R to L
