Can calcium carbonate burn in oxygen (II) fluoride? Quora
Jul 17, 2016· Answer Wiki. Calcium carbonate decomposes to calcium oxide (CaO) and carbon dioxide (CO2) at a high temperature of 825 degree C. Oxygen (II) fluoride (OF2) is unstable, and it easily decomposes to fluorine and oxygen at temperatures above 2oo degree C. So, if the fluoride is passed over heated CaCO3, the following reactions are likely to occur,...
