Of course, you could not expect that the number of unknowns will always be equal to the number of equations. This system could be solved by using the Gaussian elimination method. Now we can rewrite this system in matrix form:

Here we have five equations for four unknowns, however, the last one is dependent on the fourth, so it can be omitted. They will form a system of linear equations: Then we write the balance equations for each element in terms of the unknowns: We start by introducing unknown coefficients: Let me illustrate this method by example. Therefore this method could be used for any type of chemical reaction (including redox reactions). So, you just need to create a set of algebraic equations expressing the number of atoms of each element involved in the reaction and solve it. Balancing chemical equations is the process of ensuring the conservation of matter. Therefore, the number of each type of atom on each side of a chemical equation must be the same. The algebraic method is based on the Law of Conservation of Mass – that matter can neither be created nor destroyed.

This chemical equation balancer uses the algebraic method – which is usually quite complex for manual calculations, however, it fits the computer program perfectly.

The last two are used for redox reactions.

Examine only the elements that change their oxidation number and insert coefficients so the number of electrons lost equals the number of electrons gained. First, assign oxidation numbers to the elements in each substance. Take several minutes and try to balance this equation the multitude of elements involved makes it a challenging exercise.įortunately, such complicated reactions usually involve oxidation and reduction, and the oxidation numbers of each element make it much easier to determine the coefficients for a balanced reaction. Here is the unbalanced reaction without any coefficients: An example is the use of concentrated nitric acid to dissolve copper metal.

The coefficients of the three substances are chosen so the reaction is properly balanced.Īlthough the brief reactions described to this point may be quickly balanced by inspection or trial‐and‐error, chemistry is rich in complicated reactions that cannot be intuitively balanced. With exactly four hydrogen atoms and two oxygen atoms on each side.
