CuSo4 + Ag = CuSo4 + Ba(OH)2 = CuSo4 + Fe2O3 = CuSo4 + BaCl2 =

Question

CuSo4 + Ag =

CuSo4 + Ba(OH)2 =

CuSo4 + Fe2O3 =

CuSo4 + BaCl2 =

Answer 1

CuSo4 + Ag = не идет

CuSo4 + Ba(OH)2 = Сu(OH)2 + BaSO4

CuSo4 + Fe2O3 = не идет

CuSo4 + BaCl2 =СuCl2 + BaSO4

Answer 2

CuSO4 + Ag = не идет

CuSO4 +Ba(OH)2 = Cu(OH)2 + BaSO4

CuSO4 + Fe203 wtf???

CuSO4 + BaCl2 = CuCl2 + BaSO4
