1)Cu(NO3)2 + Na2S = 2)FeS + HCl = 3)Cr(SO4)3 + NH4OH =4)KNO3 + Na2SO4 =5)Na2S + H2SO4...

Question

1)Cu(NO3)2 + Na2S =
2)FeS + HCl =
3)Cr(SO4)3 + NH4OH =
4)KNO3 + Na2SO4 =
5)Na2S + H2SO4 =

полное ионное уравнение!!!! надо сделать помогите

Answer 1

1) =CuS+2NaNO3
2)= FeCL2+H2S
3) = Cr(OH)2+(NH4)2SO4
4) = NaNO3+K2SO4
5) = Na2SO4+H2S
