65111 Chemistry 1 – Complete Notes (HD 92) | Lectures 1-10 Summary + Worked Examples

Description

Comprehensive, exam-ready summary notes for 65111 Chemistry 1 — the exact notes I used to achieve a High Distinction (92) in this subject. Covers the entire semester (Lectures 1–10) in a clean, colour-coded, easy-to-scan format. Written and structured in my own layout to condense lectures, readings and textbook content into one streamlined study resource. Perfect for staying on top of weekly content and for exam revision — every major topic is broken down into clear definitions, summary tables, and step-by-step worked examples. TOPICS COVERED: - Atomic structure – subatomic particles, atomic number, mass number, isotopes, atomic weight - Periodic table, ions & ionic compounds, solubility rules, precipitation reactions - The mole, limiting reagents, reaction & theoretical yield - Percent composition & empirical formulas - Titrations and concentration calculations - Combustion reactions & combustion analysis - Oxidation numbers & balancing redox equations (acidic & basic) - Chemical equilibrium – Kc, ICE tables, reaction quotient, Le Chatelier's principle - Acids & bases – Arrhenius, Brønsted-Lowry, conjugate pairs, pH, acid strength - Atomic models & quantum numbers - Periodic trends – atomic/ionic size, ionisation energy, electronegativity - Bonding – ionic, covalent, metallic - Lewis diagrams, formal charge, VSEPR & molecular geometry - Hybridisation, sigma & pi bonds, bond length & bond enthalpy - Bond & molecular polarity - Intermolecular forces – London dispersion, dipole-dipole, hydrogen bonding, ion-dipole - Properties of solids, viscosity & surface tension Includes worked numerical examples for stoichiometry, limiting reagents, empirical formulas, combustion analysis, redox balancing and formal charge — the calculation-heavy areas most people lose marks on. Clear, consistent formatting throughout. Hand-drawn diagrams where helpful. A complete, HD-standard one-stop summary so you don't have to build your own from scratch.
