I think....
Pb(NO3)2 + Na2S -> PbS + 2(NaNO3)
If someone knows for sure please kill my answer.
1. Add a small quantity of the FeCl3 solution into the Na2S(aq.). 2FeCl3+3Na2S=2FeS↓+6NaCl+S↓ the following is the ionic reaction equation 2Fe3+ + S2- = 2FeS↓+ S↓ 2. Add a small quantity of the Na2S solution into the FeCl3(aq.) 2FeCl3 + Na2S =2FeCl2 + 2NaCl + S↓ the following is the ionic reaction equation 2Fe3+ + S2- = S↓ + 2Fe2+
CdBr2 + Na2S --> CdS + 2NaBr.
There will be no reaction. It will remain a mixture.
cacl2 plus na2s equals cas plus
The chemical formula of sodium sulfide is Na2S.

Na2S(aq) + ZnCl2(aq) --> 2NaCl(aq) + ZnS(s)
Na + 2S --> Na2S Sodium and Sulphur yield Sodium Sulphide.
CdBr2 + Na2S --> CdS + 2NaBr.
No, there is no reaction/
Sodium sulfide
There will be no reaction. It will remain a mixture.
The chemical equation is:2 Sr(NO3)2 + 2 Na2S = 4 NaNO3 + 2 SrS
NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
cacl2 plus na2s equals cas plus
That no matter is lost during the reaction. That is why the number of atoms of a specific element on one side of the reaction is equal to the number of atoms on the other side. Na2S + 2HBr -------> 2NaBr + H2S #of atoms................ #of atoms 2Na..............................2Na 1S................................1S 2H............................... 2H 2Br.............................. 2Br
For the molecular balance of the equation it would be: CuSO4 (aq) + Na2S (aq) = CuS (s) + Na2SO4 (aq). For the net ionic balance of the equation it would be: Cu2+ (aq) + S2(aq) = CuS (s).
