Study notes
Identify the reaction type: Zn + CuSO₄ → ZnSO₄ + Cu. Step 1: Count reactants: Zn (element) + CuSO₄ (compound). Step 2: Products: ZnSO₄ (compound) + Cu (element). Step 3: Pattern: element + compound → compound + element — one element replaced another. Step 4: This matches A + BC → AC + B. Answer: displacement reaction (zinc displaces copper).
