    Complete ionic equation:

    2H²⁺ (aq) + SO₄²⁻ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + Ca²⁺ (aq) + SO₄²⁻ (aq)

    Net ionic equation:

    2H²⁺ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + Ca²⁺ (aq)

    Explanation:

    Chemical equation:

    H₂SO₄ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + CaSO₄ (aq)

    Balanced chemical equation:

    H₂SO₄ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + CaSO₄ (aq)

    Complete ionic equation:

    2H²⁺ (aq) + SO₄²⁻ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + Ca²⁺ (aq) + SO₄²⁻ (aq)

    Net ionic equation:

    2H²⁺ (aq) + CaCO₃ (s) → H₂O (l) + CO₂ (g) + Ca²⁺ (aq)

    Complete ionic equation: 2 H⁺ (aq) + SO₄²⁻ (aq) + CaCO₃ (s) → H₂O (I) + CO₂ (g) + Ca²⁺ (aq) + SO₄²⁻ (aq)

    Net ionic equation: 2 H⁺ (aq) + CaCO₃ (s) → H₂O (I) + CO₂ (g) + Ca²⁺ (aq)

    Explanation:

    The molecular equation includes all the species in the molecular form.

    H₂SO₄ (aq) + CaCO₃ (s) → H₂O (I) + CO₂ (g) + CaSO₄ (aq)

    The complete ionic equation includes all the ions and the molecular species.

    2 H⁺ (aq) + SO₄²⁻ (aq) + CaCO₃ (s) → H₂O (I) + CO₂ (g) + Ca²⁺ (aq) + SO₄²⁻ (aq)

    The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the molecular species.

    2 H⁺ (aq) + CaCO₃ (s) → H₂O (I) + CO₂ (g) + Ca²⁺ (aq)
