125s Classroom → 30s Sub-90 Target27-Q Chemistry Mock
Archetype Sub-90 Dry-Wipe Invariant (Periodic Table Trends (Groups 1, 17, 18), Metal Reactivity Displacement & Extraction Series): Group 1 vs Group 17 opposite rules: Down Group 1 -> Reactivity UP, Melting Point DOWN. Down Group 17 -> Reactivity DOWN, Boiling Point UP. Extraction threshold: above Carbon (Al, Mg, Na) = Molten Electrolysis; below Carbon (Fe, Zn, Cu) = Carbon Reduction.
