Complete and balance each of the following equations for gas evolution reactions. (express your answer as a chemical equation. identify all of the phases in your answer) hclo4(aq)+k2co3(> ! and with parts b and c.

1) Balanced chemical reaction:

2HClO₄(aq) + K₂CO₃(aq) → K₂CO₃(aq) + CO₂(g) + H₂O(l).

2) Balanced chemical reaction:

HC₂H₃O₂(aq) + LiHSO₃(aq) → LiC₂H₃O₂(aq) (aq) + SO₂(g) + H₂O(l).

3) Balanced chemical reaction:

(NH₄)₂SO₄(aq) + Ca(OH)₂(aq) → CaSO₄(s) + 2NH₃(g) + 2H₂O(l).

CaSO₄ (calcium sulfate) is insoluble in water.

1) Aqueous perchloric acid reacts with aqueous potassium carbonate to form aqueous potassium perchlorate, carbon dioxide gas and water.

2HClO₄(aq) + K₂CO₃(aq) → 2KClO₄(aq) + CO₂(g) + H₂O(l).

2) Aqueous acetic acid reacts with aqueous lithium bisulfite to form aqueous lithium acetate, sulfur dioxide gas and water.

HC₂H₃O₂(aq) + LiHSO₃(aq) → LiC₂H₃O₂(aq) + SO₂(g) + H₂O(l).

3) Aqueous ammonium sulfate reacts with aqueous calcium hydroxide to form a white precipitate of calcium sulfate, ammonia gas and water.

(NH₄)₂SO₄(aq) + Ca(OH)₂(aq) → CaSO₄(s) + 2NH₃(g) + 2H₂O(l).
