2-5.
Fe + 2CuCl = 2Cu + FeCl₂ Fe₂O₃ + 3H₂ = 3H₂O + 2Fe
3Zn + 2FeBr₃ = 3ZnBr₂ + 2Fe 3PbO + 2Al = Al₂O₃ + 3Pb
3HgCl₂ + 2Al = 2AlCl₃ + 3Hg Cr₂O₃ + 3Mg = 3MgO + 2Cr
Mg + 2H₂O = H₂ + Mg(OH)₂ 2Al + 6H₂O = 2Al(OH)₃ + 3H₂
2-6.
2KClO₃ = 2KCl + 3O₂ 3KClO = KClO₃ + 3KCl
2NaNO₃ = 2NaNO₂ + O₂ NH₄NO₃ = N₂O + 2H₂O
2CuOH = Cu₂O + H₂O NH₄NO₂ = N₂ + 2H₂O
2Al(OH)₃ = Al₂O₃ + 3H₂O (CuOH)₂CO₃ = 2CuO + H₂O + CO₂
