Frequently Asked Questions

How do you balance a chemical equation?

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.

What is the law of conservation of mass in chemistry?

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.

Can this chemical equation balancer solve any equation?

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.

Is this chemical equation balancer free to use?

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.

What types of chemical reactions can I balance?

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).

How accurate is this chemical equation balancer?

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.

Can I use this for chemistry homework and exams?
