This simulation begins in the period around 1870 when chemistry is beginning to be organized. The concept, introduced by Kekulé and Couper, of tetravalent carbon atoms capable of linking to each other has permitted the rise of structural concepts in organic chemistry.
In chemistry lectures we have little time to discuss the history of chemistry. This simulation begins with the development of valence concepts in the 19th century. We will step back into the 19th century to see how theories of chemical combination changed during that time.
Organic Nomenclature is a drill-and-practice tutorial on naming simple organic compounds and drawing structures consisting of multiple-choice questions.
Inorganic Nomenclature is a drill-and-practice tutorial on naming simple inorganic compounds and writing chemical formulas consisting of multiple-choice questions.
The Netorials cover selected topics in first-year chemistry including: Chemical Reactions, Stoichiometry, Thermodynamics, Intermolecular Forces, Acids & Bases, Biomolecules, and Electrochemistry.
General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
ChemPages Laboratory covers more than 30 laboratory techniques and items of equipment. It teaches introductory chemistry students what they need to know--before they come into the lab.
Chemistry truly does come to life through this collection of pictures, animations, and movies depicting chemical reactions and techniques. The Chemistry Comes Alive! collection includes hundreds of high quality movies and thousands of still pictures.
