Higgins · Answer 1

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.
