    Aqueous Reactions Study Guide

    Introduction Water is the most abundant (and important, besides oxygen) substance on Earth. It is found in large amounts in cells and blood. Water is an excellent solvent and has a high boiling point, high surface tension, high heat vaporization, and low vapor ...

    Chemistry and Gases Study Guide

    Introduction Many gases are colorless substances we take for granted. They continually surround us and supply us with needed oxygen and supply plants with needed carbon dioxide. Gases' unique property of compressibility allows for quick and observable changes. ...

    Thermochemistry Study Guide

    Introduction Thermodynamics is the study of energy and its processes. Energy can exist aspotential energy (an object at rest) or kinetic energy (an object in motion). Chemical energy, a form of kinetic energy, can be calculated ...

    Atomic Structure Study Guide

    Introduction Electrons not only orbit around the nucleus of an atom, but they also move to higher and lower orbits also called higher and lower energy levels. These transitions require energy to move to a higher orbit and release energy to move ...

    Bohr Atom and Electron Configuration Study Guide

    Introduction An electron's position in an atom or ion can be described by determining its electron configuration and orbital diagram. These representations of an atom or ion can explain physical and chemical properties of the substance, including magnetic ...

    Molecular Structure Study Guide

    Introduction Three-dimensional structures showing shape, geometry, and valance electrons provide a model for comprehending the arrangement of atoms in a molecule. Molecular geometries play an important part in the intramolecular and intermolecular properties of a ...

    Nomenclature and Isomerism Study Guide

    Introduction Organic chemistry is the study of the structure and reactivity of compounds containing carbon. Carbon is the backbone of more compounds than all other elements combined. The strength of the carbon-carbon bond allows for an infinite number of ...

    pH of Acids and Bases Study Guide

    Introduction The applications of acid-base chemistry extend beyond what was learned in Lesson 6, "Aqueous Reactions." The acidity of an acid solution can be measured by its pH, and equilibria can be established between an acid and a base to create a ...
