![]() In such cases, I took the precise value: e.g., 58.933194 for Co. The first one contains the elements for which a value with the corresponding uncertainty is given: e.g., '58.933 194(3)' for Co.Based on how the atomic weight is defined therein, there are three categories of elements. The weights were parsed from the tables grabbed directly from the references above. The atomic weights and names of the elements which are used here were approved by IUPAC and CIAAW in 2021-2022 and are contained in the periodicTable variable in the chemCalc.js file. In any case, if you don't believe me, you can easily check it out by testing it manually or inspecting the source code before using it in any crucial calculations. I'd say that, as of now, the app is time-tested and should be quite reliable. This means that both "H2 + O2 = H2O" and "H2 O2=H2O" are valid, and the second one is obviously easier to type. The reagents or products must be separated with at least one whitespace or "+" character. Well, this is pretty straightforward - type the formula or equation, and voilà! The only thing that comes to my mind that isn't obvious is related to the separators in the equation input. If you'd like to do this, though, please make sure to refresh the page before saving, because I've noticed that the browser sometimes does something weird when you save the page with the calculation results already in it. ![]() a complete webpage) and use it without Internet access. It is written in vanilla JS and works offline in the browser (that is, in any more or less modern Firefox and Chrome-based browser). You can verify these results with our chemical equation balancer.This is a very small app that allows you to calculate molar masses, balance chemical equations, and compute the product or reagent masses. ![]() So, the equation is balanced now with the same number of each type of atom on both sides. To balance hydrogen, add a coefficient of 2 in front of H2O:įinally, check and balance the oxygens by adding a coefficient of 2 in front of O2: Now, the carbons are balanced, but the hydrogens and oxygens are not. Oxygen (O): 2 on the left, 3 on the rightĪs we see number of atoms of carbon is already balanced in the above unbalanced equation.Hydrogen (H): 4 on the left, 2 on the right.Carbon (C): 1 on the left, 1 on the right.Let's balance the equation for the combustion of methane (CH4) with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). That's how you balance the equation! Example: Repeat the second step: Adjust the coefficients until the number of atoms is the same on both sides.Adjust the numbers (coefficients) in front of one substance.Count the atoms on both sides of the equation.How to Balance Chemical Equations?Īn unbalanced chemical equation could be balanced by following these steps: This balancing process involves applying principles of stoichiometry, where the coefficients in the balanced equation not only represent the relative amounts of reactants and products but also convey the mole ratios between them. It ensures that the fundamental law of conservation of mass is maintained, which states that the quantity of each element is the same before and after the reaction occurs. Also, separate molecules and atoms contained within the given equationĪ balanced chemical equation is a representation of a chemical reaction that shows the exact numbers of atoms or molecules involved in the reaction on both the reactant and product sides. The calculator balances the equation by showing all coefficient proportions.Use the given Periodic Table to add the chemical equation that you need to balance.Once balanced, it ensures that the atoms for each element will remain equal on both sides of the chemical equation. Balancing chemical equations calculator automatically balances the chemical equations by adjusting the coefficients of reactants and products to ensure the conservation of atoms.
