Question

what is the oxidation half reaction, reduction half reaction, and the complete balanced reaction of the following?
(a) Al(s) + MnO4‾(aq) → MnO2(s) + Al(OH)4‾(aq)
(b) Cl2(g) → Cl ‾(aq) + ClO ‾(aq)
(c) NO2‾(aq) + Al(s) → NH3(g) + AlO2‾(aq)
(d) MnO4‾(aq) + S2-(aq) → MnS(s) + S(s)
(e) CN ‾(aq) + MnO4‾(aq) → CNO‾(aq) + MnO2(s)
(f) Cu(s) + NO3‾(aq) → Cu2+(aq) + NO(g)
(g) Cr2O72-(aq) + Cl ‾(aq) → Cr3+(aq) + Cl2(g)
(h) Pb(s) + PbO2(s) + H2SO4(aq) → PbSO4(s)
(i) Mn2+(aq) + NaBiO3(s) → Na+(aq) + Bi3+(aq) + MnO4‾(aq)
(j) H3AsO4(aq) + Zn(s) → AsH3(g) + Zn2+(aq)
(k) As2O3(s) + NO3‾ (aq) → H3AsO4(aq) + NO(g)
(l) Br ‾(aq) + MnO4‾(aq) → Br2(l) + Mn2+(aq)
(m) CH3OH(aq) + Cr2O72-(aq) → CH2O(aq) + Cr3+(aq)

Answer 1

H2O2 (aq) +MnO4 - → Mn2+ (aq) + O2 (g) problem
