#BALANCING CHEMISTRY CALCULATOR MANUAL#

Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Thus, Na3PO4 - correct form, na3po4 - incorrect form. Enter either the number of moles or weight for one of the compounds to compute the rest. Compare: Co – cobalt and CO – carbon monoxide. Note: Always use the upper case for the first character in the element name and the lower case for the second character, as in the periodic table. The returned solution is then used to display the balanced equation. Therefore, the calculator below simply parses the chemical reaction, creates a system of linear equations and feeds it to the above-mentioned Gaussian elimination calculator. In short, it just keeps all fractions, and gets to a whole integers solution at the end. I have created a special calculator that implements the Gaussian elimination method – /6200/ – in the form suitable for chemical reactions. However, the Gaussian elimination method actually could find a solution for any number of equations and unknowns. 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.

Ion-electron method, or half-reaction method.Inspection method, or 'hit & trial' method.There are several methods of balancing chemical equations:
