The gizzard: The bird stomach's second chamber is known as the gizzard. If you've ever eaten a chicken gizzard you know how tough and rubbery it is. To accomplish what the gizzard does, it absolutely must be tough, for the gizzard's main function is to grind and digest tough food.
C12H22O11 + 12 O2 Â® 12 CO2 + 11 H2O This illustrates the methods used for writing balanced reaction equations: 1  Determine the reactants and products. In this case, the products are CO2 and H2O, determined by common sense. 2  Apply the fundamental principle of conservation of atoms.
This does not obey the law of conservation of mass. Therefore we have to balance the reaction to obey the law of conservation of mass. If we put 2 in front of H2 and 2 in front of H2O the chemical equation would be balanced. 2 H2 + O2 --> 2 H2O. Now we look at the balanced chemical equation, we found out that there are 4 hydrogen atoms and 2 oxygen atoms on the left side of the reaction, and there are also 4 hydrogen atoms and 2 oxygen atoms on the right side of the reaction.
