You won't spill any acid on the spectrometer in this lab. Choose solutions from the vast database and mix 'em together till the cloned cows come home. Marvel as the chemical solutions react in real time. http://www.merlot.org/merlot/viewMaterial.htm?id=83322 VR Molecules presents dynamically and interactively the vibration and rotation modes for 24 molecules (out of a more extensive list) containing up to twelve atoms. It allows the user to create and save on his or her hard disk documents containing, much in the same way as Power Point presentations, up to 10 "pages״, each featuring one or two molecules with specific parameters (viewpoint, active modes, etc.). These presentations can be made available through the Internet, with optional sound and text explanations associated with each page.The latest, augmented version of VR Molecules, called VR Molecules Pro 1.1, is available online as well as in a stand-alone version (Mac and Windows).To view a video of the award winning author, go to View VR Molecules - Chemistry Award Winner 2007 video VR Molécules est un logiciel de simulation (en ligne et en mode local) permettant de visualiser et d'explorer les modes de vibration et de rotation des molécules (24 molécules sont disponibles).Il peut tout aussi bien être utilisé par le professeur pour préparer des démonstrations en classe, intégrer des animations (interactives ou non) dans ses documents HTML, que par les étudiants pour revoir les démonstrations présentées en classe et explorer par eux-mêmes la vibration et la rotation des molécules.La plus récente version (1.12) de VR Molécules, est accessible en deux versions : en ligne et en mode local (à télécharger, pour Mac et Windows). http://www.merlot.org/merlot/viewMaterial.htm?id=88586 An effective tool to help students learn about all aspects of the ideal gas law. One of the best web gas law simulations. http://www.merlot.org/merlot/viewMaterial.htm?id=84217 3DMolSym is an educational program designed to visualize the symmetry elements of molecules and to animate the corresponding symmetry operations in an interactive 3D environment.It is aimed to help chemistry students conceive the symmetry properties of the molecular structure. 3DMolSym includes a database with symmetry and geometry data of 48 organic and inorganic molecules, corresponding to all point groups of chemical interest. http://www.merlot.org/merlot/viewMaterial.htm?id=393756 The collection of interactive simulations covers a wide range of general chemistry topics, with each simulation addressing key concepts and enable students to practice and teachers to demostrate these topics.Chapter 2 Periodic Table Coulomb's Law Names and Formulas of Ionic CompoundsChapter 3 Compounds, Molecules, and Moles Limiting ReactantsChapter 4 Acid Ionization Solubility of Ionic Compounds The pH Scale TitrationsChapter 5 Calorimetry Measuring Heats of Reaction Heat Transfer Between Substances Hess's Law Specific Heat CapacityChapter 6 Atomic Absorbtion and Emission Planck's EquationChapter 7 Atomic Electron Configurations Electron Configurations of Ions Atomic Orbital Energies Effective Nuclear Charge, Z* Electron Configurations 1 Paramagnetic and Diamagnetic Atoms Sizes of Atoms and IonsChapter 8 Bond Energy and Delta H of Reaction Determining Electron Pair Geometry Determining Molecular Polarity Determining Molecular Shapes 1 Determining Molecular Shapes 2 Drawing Lewis Structures 1 Drawing Lewis Structures 2 Resonance StructuresChapter 9 Metallic Bonding: Band Theory Molecular Orbital Diagrams of Homonuclear Diatomic Species Molecular Fluxionality Molecular Orbital Theory Predicting Paramagnetism in Molecules Chapter Organic Addition Reactions of Alkenes Nomenclature of AlkanesChapter 10 Distribution of Molecular Speeds Gas Density The Ideal Gas Law Kinetic Molecular TheoryChapter 11 Boiling Points of Simple Organic Compounds The Classium-Clapyron Equation Vapor Pressure of Liquids Vapor PressureChapter 12 Chapter 13 Concentration Dependence of Reaction Rates Determining The Rate Equation: Graphical Method Reaction Coordinate Diagrams Temperature Dependence of Reaction Rates The Arrheius EquationChapter 15 Chromatography and Equilibrium Disturbing a Chemical Equilibrium Equilibria and Volume The Meaning of the Equilibrium Constant Equilibrium Constant Expressions Equilibrium Expressions The Equilibrium StateChapter 16 Acid-Base Properties of Water Acid-Base Reactions Hydrolysis The pH ScaleChapter 17 Buffer Solutions The Common Ion Effect Common Ion Effect in Acid-Base Systems pH of Buffer Solutions Precipitation Reaction Systems Preparing Buffer Solutions Solubility and pH Solubility Product Constant pH Titration CurvesChapter 18 Free Energy and Temperature The Second Law of Thermodynamics Thermodynamics and the Equilibrium ConstantChapter 19 Standard PotentialsChapter 20 Binding Energy Radioactive Decay Stability of Isotopes http://www.merlot.org/merlot/viewMaterial.htm?id=84210 Interactive molecular visualization of molecular normal modes of vibration.3DNormalModes is a molecular visualization educational program that provides a convenient way to illustrate how a molecule vibrates and the properties of its normal modes of vibration in a real 3D environment. http://www.merlot.org/merlot/viewMaterial.htm?id=77003 this calculator obtain the ph of a disolution knowing the type of substance ( acid or base), the constant, and the initial concentration. http://www.merlot.org/merlot/viewMaterial.htm?id=82638 Simple ionic bonds formed between two atoms follow the octet rule. Learn how to match valence electrons to make your own ionic bonds with this interactive simulation. http://www.merlot.org/merlot/viewMaterial.htm?id=82586 This interactive exercise shows progress towards an equilibrium for A + B C + D. Initial concentrations and the equilibrium constant can be chosen. Additional description of the technology and pedagogy is at http://www.cals.ncsu.edu/gn/ex/equil-disc.html http://www.merlot.org/merlot/viewMaterial.htm?id=269959 Our interactive digital overheads (IDOs) are flexible, dynamic, and interactive web-based visualization resources for the chemistry classroom. These learning and teaching aids can be used in diverse classroom settings at different educational levels. The tools target many of the topics traditionally addressed in the general chemistry curriculum, and are widely available to chemistry instructors and students.Our visualization tools are designed so that they can be displayed on a large screen using a video projector in the classroom. They have been developed as stand-alone Java applets or Flash movies that instructors can easily access and display in conjunction with conventional overheads or Power Point slides. These resources work virtually as interactive digital overheads (IDOs) that instructors may use to better explain a concept or idea, to start and guide a discussion, or to pose questions or problems to their students. Their generic design allows users to adapt the tools to their particular interests and needs.The development of our IDOs is in part motivated by the recognition that although chemistry instructors may share similar learning goals, many of them have varied ideas about what kinds of questions or problems are best suited to help students comprehend or apply a concept, when it is most appropriate to introduce an idea during a course, and how to most effectively engage students in thinking about chemical phenomena. In that sense, our IDOs are not prescriptive tools embedded in a rigid learning environment linked to a particular textbook, webpage, or software package. Rather, they are a collection of digital web-based teaching tools, highly adaptable to diverse teaching needs and styles, and designed to foster conceptual understanding of chemistry via interactive visualization. The development of these resources has been guided by results from educational research on visualization in chemistry, alternative conceptions, and how people learn.In order to make it easier to find the right application, tools are classified by topic on the main page. These topics include: microscopic world, atomic structure, molecular structure, states of matter, chemical reactions, chemical kinetics, and chemical equilibrium. Simple instructions and basic plug-in requirements for each of the tools are displayed before the user selects any of these resources.
