Write the formula unit equation for this reaction occurring in water: Potassium sulfate
and barium chloride is mixed to form potassium chloride and barium sulfate.
1. KSO4 (aq) + BaCl (aq) → KCl (aq) + BaSO4 (s)
2. K2SO4 (s) + BaCl2 (s) → 2KCl (aq) + BaSO4 (s)
3. 2 K3SO4 (aq) + 3 BaCl2 (s) → 6 KCl (aq) + 2 Ba3(SO4)2 (s)
4. K2SO4 (aq) + BaCl2 (aq) → 2 KCl (aq) + BaSO4 (s)
5. K2SO4 (aq) + BaCl2 (s) → 2 KCl (aq) + BaSO4 (s)
6. 2 K3SO4 (aq) + 3 BaCl2 (aq) → 6 KCl (aq) + 2 Ba3(SO4)2 (s)
