write complete ionic and net ionic equations

Question

NaS2(aq) + Cu(NO3)2(aq) ---> CuS(s) 2NaNO3(aq)

write complete ionic and net ionic equations

accessdenied · Answer

Is it NaS2  or Na2 S?   The first doesn't seem to have balanced charges (+1, -2 *2).

At any rate, a complete ionic equation just shows you the individual ions involved in the equation.  First make sure your equation is balanced chemically with the coefficients.  Then, we split up any aqueous salts into their respective ions.  Ex)  NaCl (aq)  yields  Na+(aq) + Cl-(aq).   We leave the non-aqueous parts alone such as CuS (s).

The net ionic equation means just cancelling spectator ions (ions on both sides of the yield sign) to leave the essential ions (these are the ones making up the solid on the left CuS).
