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.
In order to write a correct chemical equation, we must balance all of the atoms on the left side of the reaction with the atoms on the right side. Let's look at another example. If you use a gas stove to cook your dinner, chances are that your stove burns natural gas, which is primarily methane.n writing chemical equations, the number in front of the molecule 's symbol (called a coefficient) indicates the number of molecules participating in the reaction. If no coefficient appears in front of a molecule, we interpret this as meaning one.
