OS balance: KMnO₄ ⇒ Mn = +7; Cr₂O₇²⁻ ⇒ Cr = +6; Σ OS = q_mol

Layer 2 — Chemistryin the chemical-nomenclature subtree

Sympy-exact witness of the oxidation-state conservation identity on two textbook anchors. KMnO₄ (potassium permanganate, neutral): K at +1, O at −2 (×4), solve x_Mn + 1 − 8 = 0 ⇒ x_Mn = +7 — explaining permanganate's famously high…
