Chemical Equation Balancer
Balance chemical equations by finding the correct stoichiometric coefficients
Introduction
Chemical equation balancing is the process of adjusting coefficients to ensure that the number of atoms of each element is the same on both sides of a chemical reaction. This follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
This calculator helps you balance chemical equations by automatically finding the correct coefficients that satisfy the conservation of atoms for all elements involved in the reaction.
How to Use
- Enter reactants separated by plus signs (e.g., "H2 + O2")
- Enter products separated by plus signs (e.g., "H2O")
- Click "Balance Equation" to find the correct coefficients
- Review the balanced equation and coefficients
- Check the validation message for confirmation

Frequently Asked Questions
What is the law of conservation of mass?
The law of conservation of mass states that mass is neither created nor destroyed in chemical reactions. This means the total mass of reactants must equal the total mass of products, which is why chemical equations must be balanced.
Why do we need to balance equations?
Balanced equations ensure that the reaction follows physical laws and allows accurate stoichiometric calculations for determining reactant quantities, product yields, and reaction efficiency.
What are coefficients?
Coefficients are numbers placed before chemical formulas that indicate the relative amounts of reactants and products. They represent the molar ratios in which substances react and are formed.
