Question

CuO - CuCL2 - Cu(OH3)2
PbO - Pb(NO3)2 - Na2PbO2 - Pb(OH)2
ZnSO4 - Zn(OH)2 - ZnCL2 - Zn
уравнение реакций решите плиз ​

Answer 1

CuO + 2HCl = CuCl2 + H2O

CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl

PbO + 2HNO3 = Pb(NO3)2 + H2O

Pb(NO3)2 + Ba(OH)2 = Pb(OH)2 + Ba(NO3)2

Pb(OH)2 + 2NaOH (t)= Na2PbO2 + 2H2O

Na2PbO2 + 2H2O = 2NaOH + Pb(OH)2

ZnSO4 + 2KOH = Zn(OH)2 + K2SO4

Zn(OH)2 + 2HCl = ZnCl2 + 2H2O

ZnCl2 + Ba = BaCl2 + Zn
