Quizplus · Accepted Answer

The balanced chemical equation for the reaction between ammonium sulfide and barium chloride is $ \text{(NH}_4)_2\text{S} + \text{BaCl}_2 \rightarrow \text{BaS} + 2\text{NH}_4\text{Cl} $. In this equation, barium sulfide (BaS) is the solid product, and its coefficient is 1.
