Write the formula unit equation for this reaction occurring in water: potassium sulfate and barium chloride are mixed to form potassium chloride and barium sulfate.

1. k2so4 (s) + bacl2 (s) → 2 kcl (aq) + baso4 (s)
2. k2so4 (aq) + bacl2 (aq) → 2 kcl (aq) + baso4 (s)
3. 2 k3so4 (aq) + 3 bacl2 (aq) → 6 kcl (aq) + 2 ba3(so4)2 (s)

option 2.

K2SO4 (aq) + BaCl2 (aq) → 2 KCl (aq) + BaSO4 (s)

Explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
