Chemical Equation Balancer

Balance chemical equations automatically.

Formula

Use "->" to separate reactants and products. Use "+" to separate molecules.

Balancing Chemical Equations

A chemical equation represents a chemical reaction using symbols and formulas. Balancing a chemical equation involves ensuring that the number of atoms of each element is the same on both the reactant and product sides, adhering to the Law of Conservation of Mass.

Law of Conservation of Mass

Matter cannot be created or destroyed in a chemical reaction. Therefore, the mass of the reactants must equal the mass of the products.

Steps to Balance

  1. Count the atoms of each element in the reactants and the products.
  2. Add coefficients (numbers in front of formulas) to balance the atoms. Never change the subscripts!
  3. Check your work to ensure all elements are balanced and the coefficients are in the lowest possible whole-number ratio.
