Prawn's Shell.

It was another good time with them in Seoul Garden just now! Yune-ine, thanks for organizing it again! (:

The usual too-scientist me got a little random today and posted Junie and the rest this question:

Have you all wonder what will happen to us if we eat the prawn's shell as well?

My answer:

We'll feel bloated. Reason? Prawn's shells are calcium carbonate (CaCO3). When they arrive at our stomach, our gastric juice (hydrochloric acid) will react with the prawn's shell

CaCO3 + 2HCl ---> CaCl2 + CO2 + H2O

Note the production of CO2? So yeah.. *burp*

Somehow, this picture looks wrong. Quite disturbing lehh.
