SHS Chemistry practice questions
400 questions across 16 topics of the new NaCCA curriculum, each with a written explanation.
Chemistry builds from the atom up: what things are made of, how they bond, and what that predicts about how they behave. Year 1 covers the scientific method and atoms, periodic properties, interatomic and intermolecular bonding, the mole and mole ratios, chemical formulae and equations, and the classification and analysis of organic compounds. Year 2 covers acids, bases and salts, energy changes, chemical kinetics, dynamic equilibrium, the halogens, trends across the elements, and structure and molecular properties.
