Free online chemical equation balancer with step-by-step solutions. Balance chemistry equations instantly for homework, studying, and learning stoichiometry.
How to use: Type compounds directly or use the dropdown to select from common compounds. Separate multiple compounds with + signs.
Examples: Select H₂O, CH₄, CO₂, NaCl, etc. from the dropdown or type custom formulas.
To balance a chemical equation, follow these steps: 1) Write the unbalanced equation, 2) Count atoms of each element on both sides, 3) Add coefficients to balance each element, 4) Check that all elements are balanced. Our chemical equation balancer does this automatically and shows you each step.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. This means the number of atoms of each element must be equal on both sides of a balanced chemical equation. This is why we need to balance equations.
Our balancer can solve most standard chemical equations including synthesis, decomposition, single displacement, double displacement, and combustion reactions. It has a database of 700+ compounds and uses advanced algorithms to balance equations instantly.
Yes! Our chemical equation balancer is completely free to use. No registration required, no ads, and no limitations. Perfect for students, teachers, and anyone learning chemistry.
You can balance all major types of chemical reactions: synthesis (A + B → AB), decomposition (AB → A + B), single displacement (A + BC → AC + B), double displacement (AB + CD → AD + CB), and combustion reactions (hydrocarbon + O₂ → CO₂ + H₂O).
Our balancer is highly accurate and uses proven mathematical algorithms to ensure correct balancing. It follows the law of conservation of mass and provides step-by-step explanations so you can verify the results and learn the process.
Absolutely! Our tool is perfect for chemistry homework, studying for exams, and learning chemical equation balancing. Use it to check your work, understand the steps, and practice with our interactive exercises.
Yes! Our chemical equation balancer is fully optimized for mobile devices, tablets, and desktops. The responsive design ensures a great experience on any screen size.
