Which represents the balanced double displacement reaction between sodium chloride (na+cl-) and copper sulfate (cu2+(so4)2-) ? nacl + cu(so4) --> na2(so4) + cucl2 nacl + cu(so4) --> na(so4) + cucl 2nacl + cu(so4) --> na2(so4) + cucl2 nacl + cu(so4) --> cl(so4) + nacu

2NaCl + CuSO₄ → Na₂SO₄ + CuCl₂

Explanation:A double displacement reaction is a reaction in which two reactants or compounds reacts by exchanging anions and cations to form new compounds.In this case, NaCl exchanges Na⁺ and Cl⁻ with Cu²⁺ and SO₄²⁻ from CuSO₄ to form Na₂SO₄ and CuCl₂.The equation for the reaction is;

2NaCl + CuSO₄ → Na₂SO₄ + CuCl₂

The equation is balanced as the number of atoms of each element is equal on both sides of the equation.
