Chemistry practice across the core topics — atomic structure and isotopes, the periodic table and its trends, ionic and covalent bonding, chemical reactions and balancing equations, the mole and stoichiometry, acids and bases and pH, and energy in reactions (exothermic vs endothermic). Difficulty scales from everyday facts to multi-step reasoning, with a teaching explanation after every answer. Aligned to high-school/AP Chemistry, GED Science, and the general chemistry on the MCAT.
