D) 4
E) 6

Question

Quizplus · Accepted Answer

The reaction between potassium sulfate and barium nitrate produces barium sulfate (solid) and potassium nitrate in solution. The balanced chemical equation is $ \text{K}_2SO_4(aq) + \text{Ba(NO}_3)_2(aq) \rightarrow \text{BaSO}_4(s) + 2\text{KNO}_3(aq) $. The coefficient of the solid barium sulfate (BaSO4) in the balanced equation is 1.
