![]() We can’t change the subscripts (for example, we can’t change the 2 in H 2O).This article includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. To fix this, we can change the coefficients that come before the molecules. There is a problem, because the left side has 2 hydrogen atoms but the right side has 3. This is known as the law of conservation of mass: matter cannot be created or destroyed.Īs an example, let’s look at the unbalanced reaction of water (H 2O) with sodium (Na): We have to make sure that the reactant and product sides have identical amounts of atoms – for example, if we react molecules containing 2 atoms of hydrogen then we must produce molecules that have 2 atoms of hydrogen as well.
