WebIt decomposes to give carbon dioxide when heated up to 1200K. ... CaCO 3 +H 2 SO 4 → CaSO 4 +H 2 O+CO 2. At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. CaCO 3 → CaO + CO 2; On reacting with dilute acids, calcium carbonate gives carbon dioxide. CaCO 3 + 2HC l → CaCl 2 + H 2 O +CO 2; Application … WebApr 6, 2024 · The vapor pressure of water at 25.0 °C is 23.8 mmHg. When solid calcium carbonate is reacted with aqueous hydrochloric acid, the products of the reaction include aqueous calcium chloride, liquid water, and gaseous carbon dioxide. Calculate the volume of CO₂ gas (in L) collected over water at 25.0 °C when 39.1 g of calcium carbonate is … WebThe carbonate can be heated and the carbon dioxide produced is tested so we know when the reaction has taken place. A typical setup in shown in the figure below. In the case of copper carbonate, it is reasonably easy to observe that the reaction has taken place because no blue-green solid remains. british auto san luis obispo
