What is the chemical equation for cooking rice? What is the balanced chemical equation for the chemical reaction of cooking rice (including the formula for starch etc.)?
Essentially when rice is cooked all you are doing is adding water to it and heating it. No true chemical reaction occurs.  A way you could think of this addition of water in an equation is:
$$\ce{(C6H12O6)2 -&gt;[\Delta][water] (C6H12O6)2.xH2O}$$
Not the most accurate representation as water was not added to a crystal system but I hope this helps you understand that no real reaction is occuring.
