WHAT'S INSIDE

• 153 pages, 8.5 × 11 in, print-ready PDF with a clickable table of contents
• Exam overview: full-year, first-term, second-term, and brief forms; 70 questions in about 110 minutes; four answer choices; the periodic table and data sheet provided; calculator rules; raw scores and national percentile norms
• Atoms: quantum numbers, electron configurations, isotopes, light and atomic spectra, the photoelectric effect, and periodic trends
• Properties of matter: kinetic molecular theory, gas laws, phase changes, heating curves, phase diagrams, solutions, and colligative properties
• Bonding: lattice energy, Lewis structures, formal charge, resonance, VSEPR, polarity, hybridization, molecular orbital bond order, and intermolecular forces
• Reactions: reaction types, net ionic equations, stoichiometry, empirical formulas, limiting reagents, percent yield, and titration stoichiometry
• Kinetics and equilibrium: rate laws, integrated rate laws, Arrhenius calculations, mechanisms, K and Q, ICE tables, and Le Chatelier's principle
• Acids and bases: pH, Ka and Kb, buffers and Henderson–Hasselbalch, titration curves, indicators, and Ksp
• Thermodynamics: calorimetry, Hess's law, bond enthalpies, entropy, Gibbs free energy, and ΔG° = −RT ln K
• Electrochemistry: galvanic and electrolytic cells, reduction potentials, the Nernst equation, and electrolysis calculations
• Nuclear chemistry and laboratory math and data: decay, half-life, radiocarbon dating, significant figures, error analysis, and graph linearization
• 13 labeled diagrams, 54 key-equation boxes, and 66 worked examples
• 2 practice tests with 100 questions each (200 total), covering all ten content areas at exam level
• Complete answer keys with a worked explanation for every question
• Six-, four-, and two-week study plans, FAQs, test-taking strategies, and test-anxiety techniques

WHO IT'S FOR

• College students in General Chemistry I, General Chemistry II, or a full-year course whose final is an ACS exam
• Pre-med, pre-pharmacy, nursing, engineering, and science majors reviewing first-year chemistry
• Instructors and tutors who want a structured review and practice resource
