Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of sodium sulfide and iron(II) nitrate
Luda [366]

Answer:

Fe^2+(aq) + S^2-(aq) --------> FeS(s)

Explanation:

First let us look at the molecular equation;

Na2S(aq) + Fe(NO3)2(aq) --------> FeS (s) + 2NaNO3(aq)

Now, the net ionic equation usually shows the most important reaction that took place, in this case, the formation of the FeS precipitate.

Hence, ionically;

Fe^2+(aq) + S^2-(aq) --------> FeS(s)
