CaO is calcium oxide. P2O5 is diphosphorous pentoxide. MgO is magnesium oxide. SiO2 is silicon dioxide.
They form bases.....for eg CaO+H2O---->Ca(OH)2
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
CaCo3 heated & gives CaO+Co2
Calcium and oxygen combine to form calcium oxide, CaO.
Basic oxides are those which form bases in water as CaO, [CaO + H2O ----> Ca(OH)2 ], the oxides of Alkali and Alkaline earth metals are basic in nature.
Cao Cao has written: 'Cao Cao shi wen xuan'

Cao-Cao was born in 1973.
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
CaCo3 heated & gives CaO+Co2
Calcium Hydroxide (slaked lime) would form with the evolution of much heat. CaO + H2O -----> Ca(OH)2
it is undefined... all we know is he died at the age of 64-65... (a relatively long age span 4 a little yellow man)
Calcium and oxygen combine to form calcium oxide, CaO.
Cao Cao died when he was sixty years old.
Cao Cao's invasion of Xu Province happened in 193.
so that limestone can decompose to form CO2 and CaO
