The correct answer is:<br /><br />Reaction 1: Single Displacement - Zn + CuSO4 → ZnSO4 + Cu<br />Reaction 2: Double Displacement - BaCl2 + Na2SO4 → 2 NaCl + BaSO4<br /><br />Explanation:<br />1. In Reaction 1, zinc metal (Zn) reacts with copper(II) sulfate (CuSO4) to form zinc sulfate (ZnSO4) and copper metal (Cu). This is a single displacement reaction, where zinc displaces copper from the copper sulfate solution.<br />2. In Reaction 2, barium chloride (BaCl2) reacts with sodium sulfate (Na2SO4) to form sodium chloride (NaCl) and barium sulfate (BaSO4). This is a double displacement reaction, where the cations and anions of the two reactants exchange partners to form two new compounds.
