From the balanced chemical equations listed below, which equation best expresses the following word equation: The reversible reaction in which solid calcium carbonate yields solid calcium oxide plus carbon dioxide gas? CaCO3 (s) --- CaO (s) + CO2 (g) CaCO3 (s) CaO (s) + CO2 (g) CaO (s) + CO2 (g) CaCO3 (s) CaClO3 CaClO (s) + O2 (g)

Question

From the balanced chemical equations listed below, which equation best expresses the following word equation: The reversible reaction in which solid calcium carbonate yields solid calcium oxide plus carbon dioxide gas? CaCO3 (s) ---> CaO (s) + CO2 (g) CaCO3 (s) <---> CaO (s) + CO2 (g) CaO (s) + CO2 (g) <---> CaCO3 (s) CaClO3 <---> CaClO (s) + O2 (g)

What do you think @Shonengetsu ??

anonymous · Answer

this one is really obvious you just need to read it

anonymous · Answer

I think its the third one. And its not obvious when you don't know what the chemical symbols stand for.

CaCO3 (s) <---> CaO (s) + CO2 (g) solid calcium carbonate <---> solid calcium oxide plus carbon dioxide gas
