  • Oct 07, 2007 · I apologize I'm quite a poor drawer, and i wouldn't be able to draw the stick models on here, so I will simply describe them. NH3. Ammonia, Trigonal Pyramidal, the three Hydrogen are angled towards the bottom due to the Lone Pair of Electrons present on Nitrogen (remember that Nitrogen has 5 electrons in its outer orbital) The angle is 107 due to the lone pair.
The "Laboratory" tab gives you a sense of what it might be like to perform an experiment in a laboratory. "Models" gives you the ability to extend this knowledge by building your own models of such simulations. You can work in Virtlab without building such models, but we hope that you will give it a try.

Silberberg’s Chemistry provides a fully aligned, conceptual option for AP Chemistry. The text contains unprecedented macroscopic-to-microscopic molecular illustrations, consistent step-by-step worked exercises in every chapter, and an extensive range of end-of-chapter problems.

Molecular recycling, aka chemical recycling, is a technically proven way to put waste plastics back into circulation as virgin plastics — a 100% circular solution. But to succeed in the marketplace, technology is not enough: It’s also about business and execution.

    The model differs from previous research on video clubs in several key ways in an attempt to focus teachers on student thinking in a sustained way. I investigate the ways in which this model was effective for engaging teachers in noticing and making sense of their students' science ideas during one implementation. Results indicate that teachers ...

    Molecular Models Lab Objective: In this experiment, we will explore the polarity of a molecular by observing the arrangement of atoms in space within the molecule. Introduction: The polarity of a molecule is an important factor in determining its molecular properties.

    Chemical bonds form different shapes based on the arrangement of their atoms. To determine the shape of the molecule, the number of shared and lone pairs of electrons must be determined. To do this, you must count the available bonding electrons each atom has. Then you must determine central atoms and terminal atoms.

    A ball-and-stick model shows the geometric arrangement of the atoms with atomic sizes not to scale, and a space-filling model shows the relative sizes of the atoms. Figure 1. A methane molecule can be represented as (a) a molecular formula, (b) a structural formula, (c) a ball-and-stick model, and (d) a space-filling model.

    Why to model reactions when we can probe the real deal? Physical Chemistry is moving foward, and it is moving fast. Supported by theoretical calculations, new techniques coupled to modern mass spectrometers, like reaction intermediate fishing and InfraRed Multiphotonic Dissociation spectroscopy (IRMPD), are proven to be extremely powerful.
