Write the complete balanced equation for the following gas-evolution reaction:
Na₂SO₃ (aq) + HCl (aq) →

• A. Na₂SO₃ (aq) + 2 HCl (aq) → H₂SO₃ (g) + 2 Na (s) + Cl₂(g)
• B. Na₂SO₃ (aq) + 2 HCl (aq) → H₂SO₃ (g) + 2 NaCl (aq)
• C. Na₂SO₃ (aq) + 2 HCl (aq) → 2 NaCl (aq) + H₂O (l) + SO₂ (g)
• D. Na₂SO₃ (aq) + 2 HCl (aq) → 2 NaCl (aq) + H₂ (g) + SO₃ (g)

Answer: (C)
