Equation balancer
Type any unbalanced equation; it is balanced exactly, with every reasoning step shown.
Open the interactive simulation →How to use this simulation
- Type an equation using “->” or “=”, e.g. Fe + O2 -> Fe2O3. Write ions like Fe^3+.
- Press “Balance”, or tap one of the examples.
- Read the reasoning steps and the conservation check table.
What to notice
- Only the coefficients change — never the formulas.
- Atoms of each element, and the total charge, are the same on both sides.
Try this
Balance C3H8 + O2 -> CO2 + H2O yourself first, then check.
