It is essential for the learners to first completely understand the concept of stoichiometry. The free online stoichiometry calculator makes it possible to balance chemical equations and their proportional ratio at a specific time of the reaction. “The simple definition of Stoichiometry is to balance the proportional quantities of the reactant and the products in a chemical reaction”. We can’t change the subscripts (for example, we can’t change the 2 in H 2O).The role of Stoichiometry in balancing chemical equations is critical as it assists to explain all the steps in detail. 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.
