Note: An element’s name entered in accordance with the above syntax guide does not have to indicate a real chemical element. For example, equation C 6H 5C 2H 5 + O 2 = C 6H 5OH + CO 2 + H 2O can not be balanced, but if we replace the immutable group C 6H 5 with X then XC 2H 5 + O 2 = XOH + CO 2 + H 2O can be easily balanced. Sometimes an equation can not be uniquely balanced because it contains immutable groups in chemical compounds. The equation can be separated as H + O = H 2O and H + O = HO, each of which does have a unique solution. For example, the equation H+O=H 2O+HO has no unique solution because, for instance, two solutions are 3H+2O=H 2O+HO and 4H+3O=H 2O+2HO which are not multiples of each other. Usually it is a combination of a few different independent reactions. Multiple independent solutions – The entered equation can be balanced in an infinite number of ways. For example, the equation (NH 4) 2SO 4=NH 4OH+SO 2 has only trivial solution when all the coefficients set to zero. Impossible reaction – The entered equation represents an impossible reaction. Improper equation – The entered equation has chemical elements on the left hand side that are missing on its right hand side, or vice versa. The following notifications deserve special attention: There are a number of obvious notifications in case of error detected in the course of initial inspection of the entered equation, like Unexpected character or Brackets not balanced. Normal – The balanced equation is represented according to the above syntax guide.Small indices – The balanced equation is represented using ‘tiny’ symbols for indices and charges.However, clicking Ctrl-A and Ctrl-C you can copy the result without the tags and paste it to a DOC document keeping duly formatted indices and charges. Clicking the ‘Copy to clipboard’ button ( ) you can copy the result ‘as is’, including all the tags, and then you can paste it to any html-page. Html – The balanced equation is represented using html tags for indices and charges.Using the appropriate drop-down menu one can choose an output format for the balanced chemical equation: They are also converted automatically to the ‘normal’ form.Ī single electron can be denoted as e – (e-) or e⁻ (with ‘tiny’ minus). SO 4 -2, or denoted using the ‘tiny’ symbols, e.g. Note, that both indices and charges can be denoted in the source document using and html tags, e.g. All the spaces are ignored and symbol → is converted to =. When entering a chemical equation manually or pasting the copied equation it converts automatically to the ‘normal’ form according to the above rules. Using Chemical Equation Balancer Calculator Do not enter the state of compounds such as solids (s), liquids (l) or gases (g).

Parentheses ( ), square brackets and braces (curly brackets) =Fe.H2O for a water molecule or (NH4)2SO4 for ammonium sulfate. Indices should be entered as normal numbers after the appropriate elements or groups, e.g.There should be no a numerical coefficient before the formula. The formula of a substance should be entered using the upper case for the first character in the element’s name and the lower case for the second character (compare: Co – cobalt and CO – carbon monoxide).

The substances are separated by a plus sign (+).

Reactants and products in a chemical reaction are separated by an equal sign (=).

The method is modified for finding integer coefficients. Our chemical equation balancer calculator uses the Gauss-Jordan elimination algorithm for solving set of linear equations. But in case of complex reactions involving many compounds, it is preferable to balance equations using algebraic methods, based on solving set of linear equations. There are a number of methods for balancing chemical equations. In case of ionic reactions, the same electric charge must be present on both sides of the equation. Thus, each side of the equation must represent the same quantity of atoms of any chemical element. This is important because in a chemical reaction, the quantity of each element does not change (the law of conservation of mass). The chemical equation is the symbolic representation of a chemical reaction, with reactants on the left and products on the right hand side of the equation.īalancing chemical equations means looking for stoichiometric coefficients for the reactants and products.
