Get chemistry help, tutorials, example problems, self-quizzes, and chemistry tools so you can learn the concepts of general chemistry.Introduction to ChemistryLearn about what chemistry is and how the science of chemistry is studied.What Is Chemistry?What Is the Scientific Method?Math BasicsMath is used in all the sciences, including chemistry. To learn chemistry, you need to understand algebra, geometry, and some trig, as well as be able to work in scientific notation and perform unit conversions. Accuracy & Precision ReviewSignificant FiguresScientific NotationPhysical ConstantsMetric Base UnitsTable of Derived Metric UnitsMetric Unit PrefixesUnit CancellingTemperature ConversionsExperimental Error CalculationsAtoms and MoleculesAtoms are the basic building blocks of matter. Atoms join together to form compounds and molecules. Learn about the parts of the atom and how atoms form bonds with other atoms.Basic Model of the AtomBohr ModelAtomic Mass & Atomic Mass NumberTypes of Chemical BondsIonic vs Covalent BondsRules for Assigning Oxidation NumbersLewis Structures and Electron Dot ModelsIntroduction to Molecular GeometryWhat Is a Mole?More About Molecules & MolesLaw of Multiple ProportionsStoichiometryStoichiometry describes the proportions between atoms in molecules and reactants/products in chemical reactions. Learn about how matter reacts in predictable ways so that you can balance chemical equations. Types of Chemical ReactionsHow to Balance EquationsHow to Balance Redox ReactionsGram to Mole ConversionsLimiting Reactant & Theoretical YieldMole Relations in Balanced EquationsMass Relations in Balanced EquationsStates of MatterThe states of matter are defined by the structure of matter as well as whether it has a fixed shape and volume. Learn about the different states and how matter transforms itself from one state to another.States of MatterPhase DiagramsChemical ReactionsOnce you have learned about atoms and molecules, you're ready to examine the type of chemical reactions that can occur.Reactions in WaterTypes of Inorganic Chemical ReactionsPeriodic TrendsThe properties of the elements exhibit trends based on the structure of their electrons. The trends or periodicity can be used to make predictions about the nature of the elements.Periodic Properties & TrendsElement GroupsSolutionsIt's important to understand how mixtures behave.Solutions, Suspensions, Colloids, DispersionsCalculating ConcentrationGasesGases exhibit special properties based on having no fixed size or shape.Introduction to Ideal GasesIdeal Gas LawBoyle's LawCharles' LawDalton's Law of Partial PressuresAcids & BasesAcids and bases are concerned with the actions of hydrogen ions or protons in aqueous solutions.Acid & Base DefinitionsCommon Acids & BasesStrength of Acids & BasesCalculating pHBuffersSalt FormationHenderson-Hasselbalch EquationTitration BasicsTitration CurvesThermochemistry & Physical ChemistryLearn about the relationships between matter and energy. Laws of ThermochemistryStandard State ConditionsCalorimetry, Heat Flow and EnthalphyBond Energy & Enthalpy ChangeEndothermic & Exothermic ReactionsWhat Is Absolute Zero?KineticsMatter is always in motion! Learn about the motion of atoms and molecules, or kinetics.Factors that Affect Reaction RateCatalystsChemical Reaction OrderAtomic & Electronic StructureMuch of the chemistry that you learn is associated with electronic structure, since electrons can move around much more easily than protons or neutrons.Valences of the ElementsAufbau Principle & Electronic StructureElectron Configuration of the ElementsAufbau Principle & Electronic StructureNernst EquationQuantum Numbers & Electron OrbitalsHow Magnets WorkNuclear ChemistryNuclear chemistry is concerned with the behavior of protons and neutrons in the atomic nucleus.
