How to Balance Chemical Equations
Equalize chemical reactions step-by-step:
Enter Reaction
Input reactants and products separated by = or -> (e.g. C8H18 + O2 = CO2 + H2O).
Matrix Elimination
Engine constructs system of linear equations for each element balance.
Integer Scaling
Finds lowest common denominator to produce integer stoichiometric coefficients.
Verify Conservation
Verifies total atom counts match on both reactant and product sides.
Key Features & Linear Algebra
Linear Algebra Balancing Engine
Solves complex multi-reactant redox equations using Gaussian elimination.
Subscript & Formatting Render
Renders clean scientific chemical formulas with Unicode subscript digits.
Conservation of Mass Tally
Lists side-by-side atom count validation for every element in the reaction.
Stoichiometry Guide: Balancing Chemical Equations
According to the Law of Conservation of Mass, matter cannot be created or destroyed in an isolated chemical system. Therefore, the total number of atoms of each element on the reactant side must equal the total number of atoms on the product side.
Frequently Asked Questions
?Can stoichiometric coefficients be fractions?
While fractional coefficients like 1/2 O₂ are sometimes used in thermochemistry, standard chemical equations require the lowest whole-number integer coefficients.
