QCE ChemistryPractice Examination 6

This paper covers

• Unit 3 Redox: oxidation-state assignment, half-equation balancing, combining half-equations for full redox, oxidising/reducing agent identification
• Unit 3 Electrochemistry: galvanic vs electrolytic cells, standard electrode potentials E°, E°cell, spontaneity, Faraday's laws (Q=It, n=Q/zF), industrial electrolytic refining of copper and the anode-sludge/anode-impurity rationale
• Unit 3 Equilibrium: Kc expressions and calculations, ICE tables, Le Chatelier's Principle (concentration, pressure, temperature) with collision-theory reasoning
• Unit 3 Acids & bases: Bronsted-Lowry pairs, pH/pOH/Kw, strong vs weak, Ka/Kb, buffers (Henderson-Hasselbalch), acid-base titration calculations and indicator choice
• Unit 4 Organic structure: 12 hydrocarbon-derivative classes, IUPAC naming, isomerism, intermolecular forces and physical-property trends
• Unit 4 Synthesis & design: six reaction types, Markovnikov addition, multi-step pathways, esterification, industrial syntheses (Haber, contact, biodiesel/bioethanol), green chemistry, limiting reagent and percentage yield
• QCAA cognitions AO1–AO4 with cognitive-verb precision (explain = causal chain; deduce = logical conclusion from data; evaluate/justify = judgement against criteria using stimulus evidence), Queensland copper-smelter refinery context throughout
