Multiple substances on any side of the equation are separated from each other by a plus sign.Īs an example, the equation for the reaction of hydrochloric acid with sodium can be denoted: If not written explicitly, the coefficient is equal to 1. molecules) of that substance are involved in the reaction on a molecular basis. The coefficient specifies how many entities (e.g. Each substance is specified by its chemical formula, optionally preceded by a number called stoichiometric coefficient. Structure Ī chemical equation (see an example below) consists of a list of reactants (the starting substances) on the left-hand side, an arrow symbol, and a list of products (substances formed in the chemical reaction) on the right-hand side. The first chemical equation was diagrammed by Jean Beguin in 1615. ![]() The coefficients next to the symbols and formulas of entities are the absolute values of the stoichiometric numbers. The chemical formulas may be symbolic, structural (pictorial diagrams), or intermixed. The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. ( October 2023) ( Learn how and when to remove this template message)Ī chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas. Please help to improve this article by introducing more precise citations. All attempts have been made to have the app display Error Messages when it cannot solve a problem mathematically (even though it may be trivial from a chemistry perspective), rather than have the app crash or get stuck in an infinite loop.This article includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. The app arbitrarily attempts to give one such answer, but is not ‘aware’ of the other answers.ĥ. There are some chemical equations that have multiple solutions, from a mathematical point of view (eg degree of freedom issue). The app will try to catch these exceptions and output an error message.Ĥ. There are some chemical equations that will not be able to balance (eg use of an element in the reactant side but does not appear in the product side). It is assumed that coefficients are integer values.ģ. Note that there are a few assumptions, or limitations to this app.ġ. The app will try to catch these exceptions and output an error message. ![]() ![]() algebraically, it has multiple degrees of freedom).ĭummy-proof! Will attempt to catch chemical equations that will not be able to balance (eg use of an element in the reactant side but does not appear in the product side). Suggests a solution for formulas with multiple answers (e.g. Press the “Balance” button, and the app will print out the balanced chemical equation with coefficients.Ĭontains 108 elements of the periodic table! ![]() In addition to elements and subscripts, you can also use brackets, +, and the arrow to create your overall chemical equation. At the moment, only the first 48 elements are provided. Elements are arranged under four tabs order according to their atomic number. To use this app, enter a chemical equation, EXCLUDING COEFFICIENTS. This app will balance chemical equations by providing you with the coefficients of the equation entered. Click the 'Balance Equation' button to see the balanced chemical equation in the textbox output. Enter chemical equations by selecting elements from their respective tabs. The Equation Balancer assists high school and university students with balancing chemical equations.
