Let’s look at a few simple molecules and analyze the dipoles in their bonds by comparing relative electronegativities. Why is it important to go through all of this?Because in chemical reactions, electrons will flow from areas of high electron density to areas of low electron density. Knowing...
"It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man — social and political — and to the entire universe as a whole.”—Dmitri Mendeleev Even...
Take a look at water. Water is bound to two hydrogens and also has two lone pairs of electrons. Because of the two loan pairs, the molecule has a tetrahedral bent shape. In order to determine whether or not the molecule is polar, you have to look at the partial charge vectors. First...
Once the blasters have figured out how to set up an implosion, it's time to prepare the building. In the next section, we'll find out what's involved in pre-detonation prepping and see how blasters rig the explosives for a precisely timed demolition. ...
While the overall daylight may not significantly diminish, the environment takes on a subdued quality as the Moon's silhouette delicately encroaches upon the Sun's brilliance. It's important to emphasize that even during a partial solar eclipse, observing the event directly with the naked eye can...
Flexible multidomain proteins are key players in eukaryotic signalling networks. In response to the presence of ligands, post-translational modifications or subcellular conditions, these molecules adopt differently ‘assembled’ or ‘open’ conformations, which produce different functions (Vogel et al., 20...
In recent years, conventional chemistry techniques have faced significant challenges due to their inherent limitations, struggling to cope with the increas
Figure 14.1Water is a polar covalent molecule that's good at dissolving polar solids. Chemistrivia In some cases, the attraction of water molecules for the polar solute isn't strong enough to pull the solute molecules apart. As a result, some polar solutes don't dissolve in water. ...
Although recycling may seem like a modern concept introduced with the environmental movement of the 1970s, it's actually been around for thousands of years. Prior to the industrial age, you couldn't make goods quickly and cheaply, so virtually everyone practiced recycling in some form. However,...
