Overview
This page provides an overview and revision resources for NCEA Level 3 Chemistry, focusing on thermochemical principles, properties of particles, and exam preparation materials.
Thermochemical Principles & Properties Overview
- Level 3 Chemistry covers thermochemical principles and properties of particles and substances (AS 91390).
- The main areas include atomic structure, bonding, periodic trends, molecule shapes, and enthalpy and entropy calculations.
- Updated questions and outlines are available, including 2024 exam questions.
Key Revision Resources
- Summary sheets, last-minute reminders, and A3 page summaries help consolidate thermochemical principles.
- Revision PDFs cover atomic structure, bonding, periodic trends, shapes and polarity, and enthalpy calculations.
- Entropy basics are explained in new info sheets and notes for 2020 onwards.
Practice & Collated Questions
- Practice exam papers (with answers) are available for self-assessment.
- Collated NCEA questions (2006–2024) cover atomic trends, molecular shapes, attractive forces, enthalpy, and entropy calculations.
- These resources help identify commonly assessed topics and exam patterns.
Additional Learning Tools
- Flashcards focusing on important definitions and terms are provided.
- Student links to online resources, tutorials, and study skills are available for further support.
Key Terms & Definitions
- Thermochemistry — Study of energy changes during chemical reactions.
- Enthalpy (ΔH) — Measure of heat change at constant pressure in a chemical reaction.
- Entropy (ΔS) — Measure of disorder or randomness in a system.
- Periodic Trends — Patterns in element properties across the periodic table.
- Ionic Bonding — Chemical bonding involving the transfer of electrons from one atom to another.
- Molecule Polarity — Distribution of electrical charge over the atoms in a molecule.
