Deterministic, quantitative problem sets designed specifically for Accelerated Chemistry students. Every problem deck features seeded randomization, smart scientific notation parsing, multi-attempt grading, complete worked solutions, and a one-page printable receipt with a check code.
Particle models of matter, historical atomic theory, isotopes and mass spectrometry, light and photon energy, electron configurations, and periodic trends.
Scientific notation arithmetic, significant figures in mixed operations, ionic and covalent chemical nomenclature, percent composition, empirical formulas, and dimensional analysis.
Bond classification, Pauling electronegativity differences, Lewis structures, VSEPR molecular geometry and bond angle compression, molecular polarity, intermolecular forces, and medicinal chemistry applications.
Balancing chemical equations, conservation of matter, reaction classification patterns, macroscopic evidence, mole ratios, limiting reactants, and percent yield in cooking and industrial synthesis.
Specific heat capacity, calorimetry, heating curve thermodynamics, Hess's law reaction cycles, bond enthalpies, and collision theory reaction kinetics.
Solution concentration, volumetric dilutions, solubility curves, dynamic equilibrium, equilibrium constants ($K_{eq}$), and Le Chatelier's stress shifts.
Bronsted-Lowry conjugates, autoionization of water, pH and pOH logarithmic scales, weak acid dissociation ($K_a$), neutralization titrations, and buffer capacity.
Kinetic Molecular Theory, atmospheric pressure units, empirical gas laws, the Ideal Gas Law ($PV = nRT$), Dumas vapor molar masses, Dalton's partial pressures, and Graham's effusion law.
Check that a printed receipt matches its code, open a student's exact problem set, or make a fresh retake link for any of the 8 units.
