Empirical Tuition

Learn that covalent bonding involves non-metals sharing electrons. Simple molecules have low melting points, while giant covalent structures like diamond and graphite have high melting points. Most don’t conduct electricity.

Understand that ionic bonding involves electron transfer, forming cations and anions. Strong electrostatic forces create stable lattice structures with high melting points, conducting electricity when molten or dissolved but not when solid.

Learn about concentrations and volumes in chemistry, focusing on solute, solvent, and solution calculations. Measure concentration in moles per dm³ and grams per dm³, and use formula triangles for moles, volume, and concentration.

Learn advanced chemistry calculations, including reacting masses, percentage yield, and empirical formulas. Calculate product masses from balanced equations, compare theoretical and actual yields, and find empirical formulas through experiments. Understand the relationship between empirical and molecular formulas, and explore water of crystallisation for determining hydration in salts.

Learn the essentials of chemical formulae and calculations: writing balanced equations, calculating relative atomic (Ar) and molecular mass (Mr), and understanding moles. Explore the law of conservation of mass, balance equations, and use state symbols.

Learn about the periodic table, which organizes elements by atomic number. Understand groups, periods, and their connection to electron configurations. Explore the classification of metals, non-metals, and noble gases, focusing on properties like conductivity and reactivity.

Discover the fundamentals of atoms and molecules, including their structures and properties. Learn about protons, neutrons, and electrons, and how atoms form molecules.

Explore paper chromatography, a key method for separating mixtures based on solubility. Learn how chromatograms reveal compositions and Rf values identify substances by comparing solute and solvent distances.

Explore key methods for separating mixtures: distillation, filtration, crystallization, and chromatography. Learn how these techniques isolate components based on boiling point, solubility, and particle size.

Learn to classify substances as elements, compounds, or mixtures. Discover elements with single atoms, compounds with bonded elements, and mixtures as physically combined substances. Understand the unique properties of pure substances and the variable behavior of mixtures.

Learn to calculate solubility and interpret solubility curves. Understand factors like temperature and pressure, and measure solubility in grams per 100 grams of solvent. Explore temperature effects on solubility through experiments and master plotting and reading solubility curves.

Discover solutions and solubility: how solutes dissolve in solvents, forming solutions.

Discover the basics of the three states of matter: solids, liquids and gases. Understand how particle arrangement, movement and energy define each state and explore key transitions like melting, freezing, and evaporation.
