Ребят,помогите пожалуйста. → FeCl3 → Fe(OH)3 → Fe2O3 → Fe → FeCl2 → Fe(OH)2 → FeO → Fe; Na → Na2O2 → Na2O → NaOH → Na2CO3 → NaHCO3 → NaNO3 → NaNО2; Si → SiO2 → Na2SiO3 → H2SiO3 → SiO2 → Si → Mg2Si → SiH4.
FeCl₃ + 3NaOH = Fe(OH)₃ + 3NaCl 2Fe(OH)₂ = Fe₂O₃ + H₂O Fe₂O₃ + 3H₂ = 2Fe + 3H₂O Fe + 2HCl = FeCl₂ + H₂ FeCl₂ + 2NaOH = Fe(OH)₂ + 2NaCl Fe(OH)₂ = FeO + H₂O FeO + H₂ = Fe + H₂O 2Na + O₂ = Na₂O₂ Na₂O₂ + 2Na = 2Na₂O Na₂O + H₂O = 2NaOH 2NaOH + H₂CO₃ = Na₂CO₃ + 2H₂O Na₂CO₃ + CO₂ + H₂O = 2NaHCO₃ NaHCO₃ + HNO₃ = NaNO₃ + CO₂ + H₂O 2NaNO₃ = 2NaNO₂ + O₂ Si + O₂ = SiO₂ SiO₂ + 2NaOH = Na₂SiO₃ + H₂O Na₂SiO₃ + 2HCl = 2NaCl + H₂SiO₃ H₂SiO₃ = SiO₂ + H₂O SiO₂ + 2Mg = Si + 2MgO Si + 4Mg = Mg₂Si + 2MgO Mg₂Si + 4H₂O = 2Mg(OH)₂ + SiH₄
