Question

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

Answer 1

2NaCl + CuSO₄ → Na₂SO₄ + CuCl₂

Step-by-step 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.
