The correct order of the chemical reactions involved in this process is as follows:

Carbon reacts with oxygen to form carbon dioxide (CO2)Carbon dioxide dissolves in water to form carbonic acid (H2CO3)Carbonic acid partially dissociates into bicarbonate ion (HCO3-) and hydrogen ion (H+), forming bicarbonate (H2CO3)Bicarbonate can further dissociate into carbonate ion (CO3^2-) and hydrogen ion (H+)Carbonate ion can release carbon dioxide (CO2) when it reacts with an acid or when the pH of the solution changes

So the correct order of reactions would be: CO2 -> H2CO3 -> HCO3- -> CO3^2- -> CO2
