Explanation According to the law of conservation of mass, after a chemical reaction , the mass of the reactants is equal to the mass of the products. As atoms are not created or destroyed they simply get moved around or rearranged in a chemical reaction. A chemical reaction is always is balanced because it follows the law of conservation. The number of atoms of each element in the reactants is equal to that of the products in a balanced reaction. At the end of a chemical reaction the number of atoms will be neither greater nor lesser than the number of atoms we started with. This is also known as Lavoisier's Law. Let us discussion the formation of water from hydrogen and oxygen as an example: 2 H 2 + O 2 → 2 H 2 O Mass of reactants: Mass of hydrogen atom = 1...
