Calcium carbonate

Thermal decomposition of calcium carbonate Calcium carbonate (CaCO3) can be decomposed by heating (thermal decomposition) to make calcium oxide (CaO) and carbon dioxide (CO2). CaCO3(s) → CaO(s) + CO2(g) Reaction of metal carbonate, like calcium carbonate, with acid Metal carbonates react with acids to produce carbon dioxide, a salt and water. Limestone, being a metal carbonate, is damaged by acid rain
