CuSO4+NaOH=ZnSO4+NaCl=NaSo4+BaCl2=NaOH+H2SO4=Cu(OH)2+H2SO4=NaCO3+HNO3=

Question

CuSO4+NaOH=
ZnSO4+NaCl=
NaSo4+BaCl2=
NaOH+H2SO4=
Cu(OH)2+H2SO4=
NaCO3+HNO3=

Answer 1

1. CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4
2. Реакция не идет
3. Na2SO4 + BaCl2 = BaSO4 + 2NaCl
4. 2NaOH + H2SO4 = Na2SO4 + 2H2O
5. Cu(OH)2 + H2SO4 = CuSO4 + 2H2O
6. Na2CO3 + 2HNO3 = 2NaNO3 + H2O + CO2
