[Trương Hồng Hạnh]

(1) H₂S + O₂ => S| (A) + H₂O (B) (đk: t^o)

(2) S + O₂ => SO₂ (C) (đk:t^o)

(3) 4HCl + MnO₂ => MnCl₂ (E)+ Cl₂ (D)+ 2H₂O (B) (đk: đun nhẹ)

(4) 2H₂O + SO₂ + Cl₂ => 2HCl + H₂SO4

(5) Ba + 2HCl => BaCl2 + H2

(6) Cl₂ + H₂ => (đk:as) 2HCl

(7) Cu + H2SO4đ,n => CuSO4 + SO2 + H2O

(8) CuSO4 + BaCl2 => CuCl2 + BaSO4|

(9) CuCl2 + H2SO4 => CuSO4 + 2HCl
