![]() You never change subscripts.Ī coefficient is a whole number multiplier. When you balance a chemical equation, you change coefficients. That means we need to add coefficients to make this equation balanced.Įarlier, I mentioned that there are two ways to tell how many atoms of a particular element exist in a chemical equation: by looking at the subscripts and looking at the coefficients. When you write out the number of products, you can see that the equation isn’t balanced, because there are different amounts of each atom on the reactant side and the product side. ![]() On the product side, we have two atoms of iron and three atoms of oxygen. On the reactant side, we have one atom of iron and two atoms of oxygen. If there is no subscript or coefficient present, then you just have one atom of something. You can do this by looking at the subscripts or the coefficients. Next, you need to determine how many atoms of each element are present on each side of the equation. The products are on the right side.įor this equation, our reactants are Fe and O 2. Remember, your reactants are on the left side of your equation. The first step in balancing a chemical equation is to identify your reactants and your products. #Chemistry calculator balancing equations how toIn this section, we’re going to explain how to balance a chemical equation by using a real life example, the chemical equation that occurs when iron rusts: How to Balance Chemical Equations-Explanation and Exampleīalancing chemical equations means that you write the chemical equation correctly so that there is the same amount of mass on each side of the arrow. If your chemical equation has different masses on the left and right side of the equation, you’ll need to balance your chemical equation. That means that each side of the chemical equation needs to have the same amount of mass, because the amount of mass can’t be changed. In order for a chemical reaction to be correct, it needs to satisfy something called the Law of Conservation of Mass, which states that mass can’t be created or destroyed during a chemical reaction. The products are the substances that are made as a result of a chemical reaction. On the right side of the equation are the products. These are the materials that you start with in a chemical reaction. On the left side of the equation are the reactants. Here’s what a chemical equation looks like: Simply put, a chemical equation tells you what’s happening in a chemical reaction. In this article, we’ll talk about what a chemical equation is, how to balance chemical equations, and give you some examples to aid in your balancing chemical equations practice. ![]() A balanced chemical equation has the correct number of reactants and products to satisfy the Law of Conservation of Mass. A chemical equation tells you what happens during a chemical reaction. ![]()
