Solid iron (III) sulfide is produced when metallic iron is reacted with elemental sulfur. A temperature of 315°C is required.

Fe_(s)+S₈ - Fe₂S_3(s)

200

A precipitate of gold (III) sulfate is produced when aqueous solutions of sodium sulfate and gold (III) nitrate are mixed. An additional product is aqueous sodium nitrate. The reaction reaches a state of equilibrium.

Na₂SO_4(aq) + Au(NO₃)_3(aq) <---->  Au₂(SO₄)_3(s) + Na_3(aq)

When solid ammonium carbonate is heated to a temperature of 645°C, it decomposes into ammonia gas (NH3), water vapor, and carbon dioxide gas.

(NH₄)₂CO_{3(s) -} NH_3(g)+ H₂O_(g) + CO_2(g)

400

When solid potassium oxide is heated with carbon dioxide gas to a temperature of 112°C, solid potassium carbonate is formed.

Ka₂O_(s) + CO_2(g) -> K₂CO_3(s)

500

Solutions of sodium phosphate and barium chlorate are mixed. A precipitate of barium phosphate and an aqueous solution of sodium chlorate form.
