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.
A chemical reaction equation gives the reactants and products, and a balanced chemical reaction equation shows the mole relationships of reactants and products. Often, the amount of energy involved in the reaction is given. Dealing with the quantitative aspect of chemical reactions is called reaction stoichiometry.nergy is the driving force of all changes, both physical and chemical reactions. Energy is always involved in these reactions. If a system is more stable by losing some energy, a reaction takes place, releasing energy. Such a reaction is said to be exothermic.
