I am in 10th grade, and balancing chemical equations is my biggest nightmare. Simple equations like H₂ + O₂ → H₂O are fine, but when I see complex ones like KMnO₄ + HCl → KCl + MnCl₂ + Cl₂ + H₂O, I completely lose my way. I start counting atoms, but halfway through, I forget which elements I have already balanced. The trial-and-error method wastes so much of my time, and I often end up with the wrong coefficients. I have heard about the algebraic method and the oxidation number method.
