the answer is DECOMPOSITION... and that is the answer not CaCO3
CaO + CO2 ==> CaCO3
I'm assuming you mean the decomposition of Calcium carbonate, so: CaCO3 ---> CaO + CO2
CaCo3=Cao+Co2
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
The correct balanced equation for the reaction between CaO and CO2 to form CaCO3 is CaO + CO2 -> CaCO3. This represents the conservation of mass with one Ca, one C, and three O atoms on both sides of the equation.
CaO + CO2 - CaCO3
The balanced chemical equation for the decomposition of limestone (CaCO3) to form calcium oxide (CaO) and carbon dioxide (CO2) is: CaCO3 -> CaO + CO2
CaCO3 -> CaO + CO2
Limestone = CaCo3. Therefore :- CaCO3 --(HEAT)--> CaO + CO2 This is known as thermal decompostition.
Its hard to tell from the way you wrote it, but if its supposed to be CaCo3---> CaO + CO2, then CaCo3 is the reactant and CaO and CO2 are the products. Its simply that the elements on the left of the arrow are reactants and the ones on the right are products.
CaO + CO2 - CaCO3
This is a decomposition reaction where calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO2) upon heating.
