Question

Write a balanced net ionic equation for the reaction of CdCl2(aq) with Na2S(aq).

A) CdCl₂(aq) + Na₂S(aq) → Cds (aq) + 2 NaCl(aq)
B) Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) → CdS(s) + 2 NaCl(aq)
C) Cd²⁺(aq) + S²(aq) → CdS(s)
D) Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) → CdS(s) + 2 Na⁺(aq)

Answer 1

The balanced net ionic equation is Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) → CdS(s) + 2 Na⁺(aq).

Step-by-step explanation:

The balanced net ionic equation for the reaction of CdCl2(aq) with Na2S(aq) is option D) Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) → CdS(s) + 2 Na⁺(aq).
