How does it teach chemical equation balancing?
It walks through balancing systematically — not just giving the coefficients but teaching the method. For a redox reaction, it demonstrates the half-reaction method: separate into oxidation and reduction halves, balance atoms other than O and H, balance O with H2O, balance H with H+, balance charge with electrons, then combine and simplify. It also covers the algebraic method for complex reactions and explains when each approach is more efficient.
