Formula used
conserve every element (and charge) — solve the null space exactly

Assumptions
- Input coefficients (if any) are ignored — only subscripts define the chemistry.
- For ionic equations every charged species must be written with its charge.
- Acidic/basic redox balancing: include H₂O and H⁺/OH⁻ explicitly; charge conservation enforces electron balance.
Limitations
- A unique solution must exist — genuinely alternative pathways are rejected as underdetermined.
