About This Course
Check out the video lessons that cover all the necessary topics to give you an introduction to chemistry. Subject matter experts are only a click away to answer any questions that arise as you go through these video lessons. Use the lesson quizzes and chapter exam to test your knowledge.
|Experimental Chemistry and Introduction to Matter||Convert between measurements of the metric system, identify lab equipment, and use significant figures appropriately. Classify different phases of matter, and compare and contrast distillation and filtration.|
|Atoms||Determine atomic and mass number, explain what an isotope is, and understand Avogadro's number. Illustrate the Bohr model, and explain the theories of Dalton, Thomson, Rutherford and Millikan and more.|
|The Periodic Table||Understand how the periodic table is arranged, determine the relationship between an element's place on the periodic table and the number of valence electrons, and explain the trend in ionization energy moving across the periodic table.|
|Nuclear Chemistry||List types of radioactive decay, balance nuclear equations, and understand the relationship between mass and energy.|
|Chemical Bonding||Use and apply the octet rule, draw a Lewis symbol, and predict the charge of an atom when it becomes an ion. List properties of and name ionic compounds, write ionic formulas and more.|
|Liquids and Solids||Explain movement of particles and properties of solids and liquids using the kinetic molecular theory, interpret phase diagrams and heating curves, and describe types of crystal structures.|
|Gases||Apply the kinetic molecular theory to explain properties of gases, define pressure, convert between pressure units, and convert between Celsius and Kelvins. Calculate partial and total pressures using Dalton's law of partial pressure, and use Avogadro's, Boyle's, Charles', Gay-Lussac's, and ideal gas laws. Understand how gases react under non-ideal conditions.|
|Solutions||Explain how a solution is formed, distinguish between electrolytes and nonelectrolytes, determine solubility of a substance, make concentration and dilution calculations and more.|
|Stoichiometry||Write and balance chemical equations from word problems, use the mole ratio relating two substances, and make mole to mole and mass to mass calculations. Determine limiting and excess reactants, calculate ideal reaction yield, calculate percentage composition of an element, and determine formula of a hydrate.|
|Chemical Reactions||Write simple synthesis and decomposition reactions, use the Arrhenius theory to define acids and bases, and identify Bronsted-Lowry and Lewis acids and bases. Solve acid/base reactions, identify amphoteric compounds, calculate pH and pOH, write net ionic equations, and assign oxidation numbers.|
|Equilibrium||Explain factors that disrupt equilibrium, calculate equilibrium constant and quotient, set up a RICE table, interpret solubility constants. Describe the common-ion effect, calculate Ka or Kb, and understand buffers.|
|Kinetics||Interpret rate laws, predict effect of temperature on reaction rate, define activation energy, explain how a catalyst works and more.|
|Thermodynamics||Explain state functions, understand how energy can be transferred, use Hess's law to calculate enthalpy, calculate heat transfer, and define entropy.|
