chem-equation-balancers
This repository has four versions of chemical equation balancers. You may need to update the change the package and import paths as needed.
First Version
The first version uses a very simple inspection method that can solve simple to moderate difficulty equations. This version does not support any parentheses.

Second Version
The second version uses a procedural version of the simplified algebraic method (https://jaminsantiago.files.wordpress.com/2013/04/balancing-chemical-equations-easy-algebraic-method.pdf) along with polyatomic replacement that solve almost any chemical equation. This version supports parentheses().

Third Version
The third version is an object oriented equalivent of the second version.

Fourth Version
The fourth version takes a whole new approach compared to the others. Instead of using the simplified algebraic method(where variable space has to be accounted inside code), this uses a complete algebraic/matrix solving method. As the more number of variables seems to suggest that a stronger balancing algorithm(in-depth experiment: https://github.com/Saptak625/chem-node-charts), this method maximizes it, while also keeping internal complexities of some matrix solving to a minimum. The matrix solving method used is a custom gaussian elimination with back substitution. My hypothesis of being able to solve all chemical equations hasn't been tested yet. Any suggestions, ideas, or resources would be greatly appreciated!
