... Example: When Na2CO3(s) is heated, it will decompose to form CO2(g). Solid Na2O will also be formed as the remainder of the original compound. The Na2O(s) will slowly re-absorb CO2(g) from the air and convert back into Na2CO3(s). Other carbonates follow this same pattern, as seen in the reaction of ...
