In the question, S₂O₃ and CO₃ should be S₂O₃²⁻ and CO₃²⁻ instead.

1)
(complete) ionic equation: S₂O₃²⁻(aq) + 2H⁺(aq) + 2Cl⁻(aq) → SO₂(g) + S(s) + H₂O(l) + 2Cl⁻(aq)
net ionic equation: S₂O₃²⁻(aq) + 2H⁺(aq) → SO₂(g) + S(s) + H₂O(l)

2)
(complete) ionic equation: CO₃²⁻(aq) + 2H⁺(aq) + 2Cl⁻(aq) → H₂O(l) + CO₂(g) + 2Cl⁻(aq)
net ionic equation: CO₃²⁻(aq) + 2H⁺(aq) → H₂O(l) + CO₂(g)
