#H_2CO_3(aq) rarr CO_2(g) + H_2O(l)#

Explanation:

That was easy. Do I win £5-00...?

And in fact there might not be much actual carbonic acid. A better representation is possibly #H_2O*CO_2#, i.e. the water adduct of carbon dioxide...the which STILL participates in an acid-base equilibrium...

#H_2O*CO_2(aq) +H_2O(l)rightleftharpoonsH_3O^+ + HCO_3^-#
