The chemical reaction<br>K_2SO_4\text{ (aq.)} + BaCl_2\text{ (aq.)} \rightarrow 2KCl\text{ (aq.)} + BaSO_4\downarrow\text{ (solid)}<br>is an example of:
- A. Addition reaction
- B. Displacement reaction
- C. Decomposition reaction
- D. Double displacement reaction ✓
Correct Answer: D. Double displacement reaction
