Hydrogen bonding between water molecules. H bonding is responsible for many of the important properties of water such as high cohesion, surface tension, boiling point and its role as a universal solvent.
Using high-resolution atomic force microscopy, a hydrogen bond has been imaged for the first time. This technique is quite similar to the one used to photograph bonds breaking and reforming that was announced earlier this year.
Chemistry Review for Senior Biology Courses - This lesson package includes the lesson (student and teacher versions of the Power Point), and a student lesson handout. The Power Point is meant to review the basic chemistry concepts which will be needed in a senior level biology course. In order, the lesson covers: - Atoms - Valence Electrons - Isotopes - Ions - Lewis Dot Diagrams - Intra and Intermolecular forces - London, Dipole-Dipole and Hydrogen Bonds - Ionic and Covalent Bonds - AND…
Water is the most important liquid on earth. It is a very important compound in many science disciplines. This power point covers he properties of water which make it so important; polar, covalent, hydrogen bonding, hydrophobic, hydrophilic, cohesion, surface tension, adhesion, high specific heat, high freezing point, chemical buffer,vaporization, density anomality.
This PowerPoint presentation cover the three main types of bonds: covalent, ionic, and hydrogen bonds. Bond symbols and their meanings are also included. Examples of single, double, and triple bonds are given along with descriptions of these bonds. Ionic bonding and the characteristics of an ionic bond are discussed; an animation further adds to the description.
