this past-paper practice session covers electrochemistry and energy, carbon allotropes from graphite to C60, and practice with ionic lattices, crystallization, and mole calculations.
Explore the periodic table's groups and periods, reading valence electrons and shells, and learn metal–nonmetal properties, oxides, neutralization, and dot-and-cross diagram techniques.
Learn how metal reactivity governs extraction: metals above carbon require electrolysis, while those below carbon are extracted by reduction with carbon; explore displacement, decomposition, and thermite reactions.
Explain iron extraction from hematite in a blast furnace, including redox and acid-base reactions, slag formation, and zinc oxide production from zinc sulfide.
Explore the atmosphere, air composition (78% nitrogen, 21% oxygen, 0.9% argon, 0.04% carbon dioxide), and gas separation via liquefaction, distillation, and the Haber process for ammonia.
Explore how carbon monoxide binds to hemoglobin, impairing oxygen transport, and how sulfur dioxide and nitrogen oxides from fossil fuel combustion form acid rain, affecting ecosystems and buildings.
Explore organic chemistry basics by examining hydrocarbons, including alkanes, alkenes, and alkynes, their formulas, properties, isomerism, and key reactions such as combustion, halogen substitution, cracking, hydrogenation, and hydration.
Study carboxylic acids as a homologous series with the carboxyl group, learn naming from methanoic to propanoic acid, and cover reactions with bases, carbonates, and esterification.
