Question

Aqueous solutions of ammonium sulfide, (NH4)2 S\left(\mathrm{NH}_4\right)_2 \mathrm{~S}, and Hg(NO3)2\mathrm{Hg}\left(\mathrm{NO}_3\right)_2 react to produce HgS3\mathrm{HgS}_3 and NH4NO3\mathrm{NH}_4 \mathrm{NO}_3.
Write the overall balanced equation for the reaction. Indicate the state (s, aq) for each compound.
