Question

Осуществите превращения (номера 323, 324, 329, 330)

Answer 1

323)
CuCl₂ + 2KOH = Cu(OH)₂ + 2KCl
Cu(OH)₂ + 2HNO₃ = Cu(NO₃)₂ + 2H₂O
Cu(NO₃)₂ + Fe = Fe(NO₃)₂ + Cu
324)
2Na + 2H₂O = 2NaOH + H₂
2NaOH + BaCl₂ = Ba(OH)₂ + 2NaCl
Ba(OH)₂ + H₂SO₄ = BaSO₄ + 2H₂O
329)
MgO + 2HNO₃ = Mg(NO₃)₂ + H₂O
Mg(NO₃)₂ + 2NaOH = Mg(OH)₂ + 2NaNO₃
Mg(OH)₂ + 2HCl = MgCl₂ + 2H₂O
330)
Zn + 2HCl = ZnCl₂ + H₂
ZnCl₂ + 2KOH = Zn(OH)₂ + 2KCl
Zn(OH)₂ = ZnO + H₂O (t)
