Make the reaction equation: A) iron → iron (II) chloride → iron (II) hydroxide → iron (II) sulfate → iron b) sodium → sodium hydroxide → sodium sulfide → sodium chloride → sodium sulfate → barium sulfate c) copper → chloride copper (II) → copper (II) hydroxide → copper (II) oxide → copper (II) sulfate → copper

а) 1) Fe + 2HCl → FeCl2 + H2;

2) FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl;

3) Fe(OH)2 + H2SO4 → FeSO4 + 2H2O;

4) FeSO4 + Zn → ZnSO4 + Fe.

б) 1) 2Na + 2H2O → 2NaOH + H2;

2) 2NaOH + H2S → Na2S + 2H2O;

3) Na2S + ZnCl2 → 2NaCl + ZnS;

4) 2NaCl + H2SO4  → Na2SO4 + 2HCl;

5) Na2SO4 + BaCl2 → BaSO4 + 2NaCl.

в) 1) Cu + Cl2 → CuCl2;

2) CuCl2 + 2KOH → Cu(OH)2 + 2KCl;

3) Cu(OH)2 → CuO + H2O;

4) CuO + H2SO4 → CuSO4 + H2O;

5) CuSO4 + Fe → Cu + FeSO4.
