mathrm(NH)_(3)+mathrm(H)_(2) mathrm(~S)=(mathrm(MH)_(4))_(2)

The given chemical equation is incorrect. The correct balanced chemical equation for the reaction between ammonia (NH3) and hydrogen sulfide (H2S) is:<br /><br />\[ 2 \mathrm{NH}_{3} + \mathrm{H}_{2}\mathrm{S} \rightarrow (\mathrm{NH}_{4})_{2}\mathrm{S} \]<br /><br />In this reaction, two molecules of ammonia react with one molecule of hydrogen sulfide to produce ammonium sulfide, which is represented by the formula \((\mathrm{NH}_{4})_{2}\mathrm{S}\).
