CdBr2 + Na2S --> CdS + 2NaBr.
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+
Assuming you're reacting the two, it's 2Na + S --> Na2S.
The balanced equation is 2HCl + Na2S → H2S + 2NaCl. This is balanced as the number of atoms of each element is the same on both sides of the equation.
The formations of these compounds from elements are as follows. 2 Na + S --> Na2S 2K + I2 --> 2KI These two reagents do not react with each other.
The balanced chemical equation is: Zn(NO3)2(aq) + Na2S(aq) -> ZnS(s) + 2 NaNO3(aq)

NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
The balanced chemical equation for the reaction between mercury(II) nitrate and sodium sulfide is: Hg(NO3)2 + Na2S -> HgS + 2NaNO3
The balanced chemical equation is: Zn(NO3)2(aq) + Na2S(aq) -> ZnS(s) + 2 NaNO3(aq)
Of course they react.H2S and NaNO3 is given out.
The balanced chemical equation for the decomposition of solid sodium sulfide (Na2S) in aqueous solution is: 2Na2S(s) -> 2NaOH(aq) + H2S(g)
The balanced equation for the reaction is: 2 Na2S (s) + 3 Cu(NO3)2 (aq) -> 4 NaNO3 (aq) + 3 CuS (s)
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
When sulfur (S) reacts with concentrated sodium hydroxide (NaOH), it forms sodium sulfide (Na2S) and water (H2O). The balanced chemical equation for this reaction is: S + 2NaOH -> Na2S + H2O.
