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
No - you do not need the 2 prefix. It is simply CaO + CO2 = CaCO3
CaCo3=Cao+Co2
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
Limestone = CaCo3. Therefore :- CaCO3 --(HEAT)--> CaO + CO2 This is known as thermal decompostition.
CaCO3 --> CO2 + CaO
CaCO3 --> CaO + CO2
CaO + CO2 - CaCO3
CaCO3 -> CaO + CO2

CaO + CO2 - CaCO3
