CHEMISTRY. Nuclear Fission Animated - Free Science Videos and Lectures. Neutron slams into the nucleus of a heavy element which causes a nuclear fission creating two ligher elements (fission products) and more free neutrons.
These free neutrons are absorbed by other heavy elements which creates a chain reaction. This science video contains: nucleus, nuclear fission, neutrons, fission products, chain reaction.

Chemistry Freeware. On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet.
All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. MolView.Org is a web-based molecular viewing and modeling tool. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). The Virtual Laboratory from the ChemCollective is a personal favorite. KnowItAll Academic Edition - In a continued commitment to academia, Bio-Rad is offering this completely FREE and fully functional software package to promote learning and research in the academic community.
Chemistry. Chemistry Problems - Homework Help. Use these worked examples problems to help solve related problems in your own chemistry homework or to better grasp chemical concepts.
These are general & introductory chemistry problems, with links to related resources. Index of Worked Chemistry ProblemsThis is a one-page index of all of the worked chemistry problems on the site, arranged alphabetically and also arranged according to the order in which they are (typically) presented in a general chemistry text. Printable Chemistry WorksheetsThis is a collection of chemistry worksheets in pdf format. The answers to the questions are available on separate worksheets so you can fill them out and then check your work. Balancing Chemical EquationsHere is a step-by-step tutorial for balancing chemical equations, along with a worked example. Balancing Redox ReactionsGet step-by-step instructions for balancing redox reactions for conservation of mass and charge in electrochemistry.
ChemNet Review Modules 8-10. ChemPRIME. Chem Teaching Resources - Umea Unv. ChemTube3D. Chemsoc Timeline. We would like to invite you to suggest other items for inclusion in the chemsoc timeline.
All genuine suggestions will be considered and those accepted will be credited to the individual responsible! The events do not have to be chemistry related - just notable discoveries or incidences that are of interest to scientists and the general public. Please Email timeline@chemsoc.org with your suggestion, where possible please include the date the event/discovery took place and some basic details: where it took place, who was involved and maybe some other sources of information. You can even make predictions for inventions or discoveries that you think will be made in years to come. For example if you think teleportation will be possible in 2020, why not suggest it to us! Chemsoc's timeline artist Murray Robertson will create an an appropriate image to represent each successful entry. back to top.
KATION - Chemical links. MOLO - Database. The Molecular Logic Database is designed to provide teachers and students with easy access to our model-based activities.
The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF). The models are primarily of interactions of atoms and molecules, or rule-based genetics. The model-based activities are presented in a variety of sizes, styles, and degrees of teacher support, but a subset of Stepping Stones (See Overview of Stepping Stones) has been built to provide entries to larger domains. All activities are accompanied by: colored icons to indicate degree of support technological requirements links to concepts and disciplines links to standards links to some textbooks Activities can be accessed by typing an activity number in the field Jump to Activity at top right. Note: This database is in development.
