4.CuO-CuSO4

ДСергейД 1.
2Ba(избыток) + O2 -----> 2BaO
BaO + H2O -----> Ba(OH)2
Ba(OH)2 + SO2 -----> BaSO3 + H2O
BaSO3 + 2HCl ----> BaCl2 + SO2 + H2O
2.
Ba + 2H2O -----> Ba(OH)2 + H2
3.
Cu + Cl2 -----> CuCl2
CuCl2 + 2AgNO3 -----> Cu(NO3)2 + 2AgCl
Cu(NO3)2 + 2NaOH -----> Cu(OH)2 + 2NaNO3
Cu(OH)2 ----(t)-----> CuO + H2O
4.
CuO + H2SO4 -----> CuSO4 + H2O

ltitova11 1) 2Ba + O2 = 2BaO
BaO + H2O = Ba(OH)2
Ba(OH)2 + SO2 = BaSO3 + H2O
BaSO3 + 2HCl = BaCl2 + SO2 +H2O

2) 2Ba + 2H2O= 2Ba(OH)2 +H2

3) Cu + Cl2 = CuCl2
CuCl2 + 2HNO3 = Cu(NO3)2 + 2HCl
Cu(NO3)2 + 2NaOH = Cu(OH)2 + 2NaNO3
Cu(OH)2 = CuO + H2O

4) CuO + H2SO4 = CuSO4 + H2O
