Ответ:
а)CuSO4–>CuCl2–>ZnCl2–> Na2ZnO2–>Zn(OH)2–>Zn(OH)NO3
CuSO₄ + BaCl₂ = BaSO₄ + CuCl₂
CuCl₂ + Zn = ZnCl₂ + Cu
ZnCl₂ + 2NaOH = Na₂ZnO₂ + H₂O
Na₂ZnO₂ + 2HCl = Zn(OH)₂ + 2NaCl
Zn(OH)₂ +HNO₃ = Zn(OH)NO₃ + H₂O
Объяснение:
б)Hg(NO3)2–>Al(NO3)3–>NaAlO2 –>Al(OH)3–>Al(OH)Cl2–>AlCl3
Hg(NO₃)₂ + Al
Al(NO₃)₃ + 4NaOH = NaAlO₂ + 3NaNO₃ + 2H₂O
NaAlO₃ +CO₂ + 2H₂O= Al(OH)₃ +NaHCO₃
Al(OH)₃ + HCl = Al(OH)₂Cl + H₂O
Al(OH)₂Cl + 2HCl = AlCl₃ + 2H₂O
