About Chemical Equation Balancer
This tool balances chemical equations using a matrix-based algebraic method. It parses molecular formulas including parentheses and subscripts, then solves for the smallest whole-number coefficients.
How Chemical Equation Balancing Works
Balancing follows the law of conservation of mass — atoms of each element must be equal on both sides. The tool sets up a system of linear equations (one per element) and solves for integer coefficients using Gaussian elimination.
