![]() 21Īcid-base chemistry can be extremely confusing, particularly when dealing with weak acids and bases. The section on equilibrium calculations contains problem examples illustrating techniques such as iterative and graphical solutions of polynomials, all of which employ the "systematic" method of organizing information. This thorough treatment sets out the underlying concepts without invoking thermodynamics or complicated calculations considerable emphasis is placed on the distinction between Q and K. ![]() ![]() Second Semester / advanced 20 All about chemical equilibrium Acid-base equilibrium calculations are covered in Unit 21. Except for some stoichiometry and a discussion on pH, this section is largely qualitative. 9 Understanding acids and bases Covers the fundamental concepts of acids and bases. 8 Chemical bonding and molecular structure 8b All about chemical bonding Ten-part tutorial set on covalent bonding and polar covalence, shapes of molecules (VSEPR theory), hybrid orbitals, molecular orbitals applied to simple diatomics, introduction to transition metal d-orbital splitting and band theory of metals and semiconductors. Electrolytes: nature of dissolved ions, electrolytic conductance, ionic migration, ground conduction. Solubility and solubility products, competing equilibria, important solubility systems. 7b Solutions: their chemistry and physical properties types of solutions, expressing concentrations, colligative properties and Raoult's law, solutions of volatile substances, osmosis, distillation. Changes of state: vapor pressure, boiling, and phase maps. 7 Solids and liquids 7a States of matter condensed states, liquids, types of solids, intermolecular forces, types of molecular units hydrogen bonding and water introduction to crystals, ionic solids, cubic and close-packed lattices. Includes numerous examples of application of kinetic molecular theory and a section on real gases. 5c Why doesn't the electron fall into the nucleus Opposite charges attract, so why not? It's surprising how few textbooks explain this properly!Ħ Properties of gases: matter at its simplest A six-part treatment of the gaseous state of matter. 5b Atomic structure and the periodic table Everything you need to know in a first-year college course about the principal concepts of quantum theory as applied to the atom, and how this determines the organization of the periodic table. First-semester general chemistry 5 Getting serious about atoms 5a Primer on quantum theory of the atomA quantum catechism: elementary introduction to quantum theory in the form of a question-and-answer "primer", emphasizing the concepts with a minimum of mathematics. Pseudoscience, junk science and quackery are pervasive in our culture, and all-too-many science courses simply ignore it. 4 What is pseudoscience? How to tell the difference from science. You will need these skills in amost everything that comes later. significant figures and rounding off 3 The basics of atoms, moles, formulas, equations These five units take you through basic atomic theory and chemical arithmetic, and how chemicals are named.We hope this will motivate you get through the less-fun stuff in the first-year course! 2 Getting started in Chemistry: essential background Classification and properties of matter Beginner / First Semester 1 What is Chemistry all about, anyway? Chemistry in a nutshell: The major concepts and ideas of chemical science, and a look at some of the major currents of modern Chemistry.
