Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
When carbon dioxide is passed into lime water for a long time, calcium carbonate forms. Calcium carbonate precipitates out of the solution, turning the lime water cloudy or milky.
As slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour.....

In most industrial processes calcium carbonate and water is the product of the combination of calcium hydroxide and carbon dioxide.Calcium hydroxide + carbon dioxide → calcium carbonate + water
CaCO3 + H2CO3(aq) -> CaCO3 + H2CO3(aq) There is nothing to drive any sort of reaction at conditions near STP. At elevated temperatures such as would be found in a cement kiln, the calcium carbonate would decompose to calcium oxide and carbon dioxide while the carbonic acid would have long since evaporated to give water vapor and carbon dioxide.
No, you need Calcium Carbonate not Calcium Oxide to neutralize the acid.
Nothing I know of. Calcium carbonate is CaCO3--one atom each of calcium and carbon, three of oxygen. Ammonia is NH3--one of nitrogen, three of hydrogen. There is no element that exists in both compounds.
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 [:
You can convert CaCO3 (calcium carbonate) to Ca (calcium) by heating it at a high temperature in the presence of a reducing agent, such as carbon. This process, known as calcination, will decompose the calcium carbonate, releasing carbon dioxide and leaving behind calcium oxide. The calcium oxide can then be reacted with water to form calcium hydroxide, which can further be processed to obtain pure calcium.

When calcium carbonate reacts with an acid, it produces carbon dioxide gas, water, and a calcium salt. When calcium carbonate reacts with heat, it decomposes into calcium oxide (quicklime) and carbon dioxide gas. Lime stone, which is primarily composed of calcium carbonate, can undergo similar reactions.

When copper carbonate is heated, Cu(CO3) forms Copper Oxide CuO and CO2. When Co2 is passed through lime water, it reacts with the calcium in the solution to form the precipitate, calcium carbonate Ca(CO3) which makes the water "milky".

calcium oxide react with water it forms calcium hydroxide which is available in molasses . when molasses fermented started it leaves Co2 and alcohol. this CO2 react with calcium hydroxide it form calcium carbonate. it become hard material
