The products are calcium oxide and carbon dioxide
The equation:
CaCO3 -> CaO + CO2
its an endothermic reaction, because the it broke the bonds of the calcium carbonate (CaCO3) in order to make calcium oxide (CaO) and Carbon dioxide (CO2).
At standard temperature and pressure, calcium carbonate does not react with neutral water, but simply dissolves to a slight extent. If the water is sufficiently acidic as a result of other constituents, carbon dioxide gas can be displaced from the calcium carbonate.
Ca + 1/2 O2 => CaO, or quicklime. A more common reaction is the heating of calcium carbonate (limestone or marble) to produce oxygen and quicklime. CaCO3 => CaO +O2
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
The reaction between limestone and hydrochloric acid is an acid-carbonate reaction producing a salt, carbon dioxide and water. Limestone is chemically known as calcium carbonate (insoluble salt) and has the formula CaCO3. Hydrochloric acid is an acid and is written as HCl. When calcium carbonate and hydrochloric acid reacts the following is formed: - Calcium chloride CaCl2 (soluble salt) - Carbon dioxide (CO2 gas) - Water (H2O) Due to the carbon dioxide being released, the observer will be able to see bubbling, effervescence or fizzing. CaCO3(s) + 2H+(aq) + [2Cl-(aq)] --> Ca2+(aq) + CO2(g) + H2O(l) + [2Cl-(aq)]
its an endothermic reaction, because the it broke the bonds of the calcium carbonate (CaCO3) in order to make calcium oxide (CaO) and Carbon dioxide (CO2).
Decomposition
The gas released in the reaction of calcium carbonate with hydrochloric acid is carbon dioxide. CaCO3 + 2 HCl = CaCl2 + CO2 + H2O
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
At standard temperature and pressure, calcium carbonate does not react with neutral water, but simply dissolves to a slight extent. If the water is sufficiently acidic as a result of other constituents, carbon dioxide gas can be displaced from the calcium carbonate.
Ca + 1/2 O2 => CaO, or quicklime. A more common reaction is the heating of calcium carbonate (limestone or marble) to produce oxygen and quicklime. CaCO3 => CaO +O2
Thermal Decomposition is the name of the reaction to produce quicklime from limestone.
It will produce calcium chloride, water and carbon dioxide gas. You will observe bubbles of carbon dioxide gas being produced.
The total amount of carbon dioxide gas will stay the same if the reaction goes to completion, but if you crush the calcium carbonate, it would make the reaction occur more rapidly, because more surface area would be exposed to the hydrochloric acid.
Calcium carbonate, limestone, is baked in a kiln to produce quicklime, calcium oxide.
Most carbonate minerals are either calcium carbonate (limestone) or a mixture of calcium carbonate with magnesium carbonate (dolomite). However other metals can also combine with carbonate to produce much rarer carbonate minerals.
