(a) PH₃ + 2I₂ + 2H₂O → H₃PO₂ + 4I⁻ + 4H⁺
(b) 3NO₂ + H₂O → 2NO₃⁻ + NO + 2H⁺
(c) 3Cu + 2NO₃⁻ + 8H⁺ → 3Cu²⁺ + 2NO + 4H₂O
(d) 2MnO₄⁻ + 5H₂S + 6H⁺ → 2Mn²⁺ + 5S + 8H₂O
(e) Cr₂O₇²⁻ + 3C₂H₄O + 8H⁺ → 3C₂H₄O₂ + 2Cr³⁺ + 7H₂O
(f) NO₃⁻ + 4Zn + 7OH⁻ + 6H₂O → NH₃ + 4Zn(OH)₄²⁻
(g) 3O₂ + 2Cr³⁺ + 10OH⁻ → 3H₂O₂ + Cr₂O₇²⁻ + 2H₂O
(h) 3Pb²⁺ + IO₃⁻ + 6OH⁻ → 3PbO₂ + I₂ + 3H₂O
(i) Cr₂O₇²⁻ + 3Hg + 8H⁺ → 3Hg₂ + 2Cr³⁺ + 7H₂O
(j) N₂H₄ + 2Cu(OH)₂ → N₂ + 2Cu + 4H₂O
