Open a chapter to see its six lessons. Each lesson also sits inside that chapter of the book, right under the section it belongs to.
1Essential IdeasMatter, measurement and the language of chemistry6 lessons›
Uncertainty and significant figures
Read instruments, count significant figures and round a calculation.
Density and temperature
Float, sink and measure density; convert between the three temperature scales.
2Atoms, Molecules and IonsWhat everything is built from, and how we name it6 lessons›
Atomic theory and the subatomic particles
Add protons, neutrons and electrons and see what you have made.
Isotopes and atomic mass
Mix isotopes to their natural abundance and get the average atomic mass.
Molecular compounds and formulas
Read empirical, molecular and structural formulas of the same compound.
3Composition of Substances and SolutionsCounting atoms by weighing them6 lessons›
Empirical and molecular formulas
Turn percent data into an empirical formula, then a molecular one.
4Stoichiometry of Chemical ReactionsEquations that balance, and what they let you predict6 lessons›
5ThermochemistryWhere the energy in a reaction goes6 lessons›
6Electronic Structure and Periodic PropertiesWhere the electrons live, and why that sets the table6 lessons›
The Bohr model and line spectra
Jump an electron between levels and watch a spectral line appear.
7Chemical Bonding and Molecular GeometryHow atoms join, and the shapes that result6 lessons›
Covalent bonds, electronegativity and polarity
Slide the electronegativity difference from nonpolar to ionic.
8Advanced Theories of Covalent BondingOrbitals that overlap, mix and spread out6 lessons›
9GasesThe state we can predict with one equation6 lessons›
Gas density, molar mass and stoichiometry
Run a reaction that makes a gas and find its volume.
Kinetic molecular theory, effusion and real gases
Change temperature and mass and watch the speed distribution shift.
10Liquids and SolidsWhat holds condensed matter together6 lessons›
Phase changes and heating curves
Add heat steadily and watch temperature stall at each change.
Solids and crystal lattices
Count atoms in simple, body-centered and face-centered unit cells.
11Solutions and ColloidsMixtures that behave like one substance6 lessons›
Colligative properties
Add solute and watch freezing point, boiling point and osmosis respond.
12KineticsHow fast a reaction runs, and what controls it6 lessons›
Collision theory and activation energy
Collide molecules with the right energy and the right angle.
13Fundamental Equilibrium ConceptsReactions that run both ways at once6 lessons›
14Acid-Base EquilibriaProtons on the move6 lessons›
Strong versus weak acids and bases
Compare ionization of a strong and a weak acid at the same concentration.
Ka, Kb and percent ionization
Change Ka and concentration and track pH and percent ionization.
Polyprotic acids and salt solutions
Predict whether a salt solution turns out acidic, basic or neutral.
Buffers and titration curves
Titrate acids and bases and watch the curve and the buffer region.
15Equilibria of Other Reaction ClassesSolubility, complex ions and coupled systems6 lessons›
16ThermodynamicsWhich way a change goes on its own6 lessons›
17ElectrochemistryChemistry that moves electrons through a wire6 lessons›
18Representative Metals, Metalloids and NonmetalsThe main groups, group by group6 lessons›
Boron, aluminum, carbon and silicon
Compare the structures and uses of group 13 and 14 elements.
19Transition Metals and Coordination ChemistryThe d-block, its colors and its complexes6 lessons›
20Organic ChemistryCarbon, and the families it builds6 lessons›
21Nuclear ChemistryChanges inside the nucleus6 lessons›
The nucleus and nuclear stability
Plot nuclides on the band of stability and test binding energy.
Radiation, detection and uses
Shield alpha, beta and gamma and compare doses and medical uses.
