A balance chemical equation is based on the principle that atom are neither created nor lost in a chemical reaction. So total mass of reactants and products is conserved.
This principle is called law of conservation of mass .
The law of conservation of mass states that the mass of all the products of a chemical reaction is to the total mass of all the reactants.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
According to the law of conservation of mass, mass is neither created nor destroyed during a chemical reaction. For example, when coal is burned, the carbon atom in it changes into carbon dioxide. The carbon atom changes from a solid to a gas, yet its mass remains constant.
