Chapter 12 - Mastering Chemistry Homework. Terms in this set (17) Identify the type of interactions involved in each of the following processes taking place during the dissolution of sodium chloride (NaCl) in water. Drag the appropriate items to their respective bins. Solvent - Solvent Interactions.
Marvin JS How-To Videos. These tours demonstrate Marvin JS basics. Unified homolytic and heterolytic examples, and a quick tour of an organic example, demonstrate putting the basics together. Workspace and buttons. The Canvas and Toolbars (2 min 21 sec) Create bonds and chains. Create Single Bonds (1 min 26 sec) Draw Double and Triple Bonds (2.
Bond tool. This is the default tool, and can be used for almost all drawing tasks. Click and drag to add a bond with atoms at either end. Click an existing atom and drag to add a bond from that atom. Click an existing bond to cycle between single, double, and triple bonds. Wedge and dash bond tools. Use these tools to place wedge and dash.
In 1916, ten years before the Schrodinger wave equation, G. N. Lewis suggested that a chemical bond involved sharing of electrons. He described what he called the cubical atom, because a cube has 8 corners, to represent the outer valence shell electrons which can be shared to create a bond.This was his octet rule. Rules for drawing Lewis dot structures.
For example, butane means four carbons in a chain with no double bond. Propene means three carbons in a chain with a double bond between two of the carbons. Alkyl groups. Compounds like methane, CH 4, and ethane, CH 3 CH 3, are members of a family of compounds called alkanes.If you remove a hydrogen atom from one of these you get an alkyl group. For example: A methyl group is CH 3.
What is the ratio of hydrogen atoms (H) to oxygen atoms (O) in 2 L of water? Enter the simplest whole number ratio in order of hydrogen to oxygen, respectively. Express your answer as two integers, separated by a comma (e.g., 3,4). How many atoms of hydrogen (H) are present in 200 molecules of ammonia (NH3)? Express your answer numerically.
