Because in chemical reactions, electrons will flow from areas of high electron density to areas of low electron density. Knowing where the partial charges are is an important first step in determining where the molecule will react.Covalent bonds with large dipoles (i.e. large differences in elec...
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...

the partial negative charges on the oxygen atoms in water are attracted to the positively charged sodium ions. Because the attractions of the water molecules for the sodium and chloride ions are greater than the forces
Polar Bonds and Polar Molecules In certain cases, the individual bonds of a molecule are polar in nature but the molecule itself is not. This occurs when the partial charges cancel each other out due to equal strength and opposite physical orientation. For example, the carbon dioxide molecule ...
aThrough a meta-analysis of the experimental literature we find an appreciable fraction (indicated by the red shaded region of each subplot) of protein molecules bypass chaperones in vitro even though they are not folded (i.e., have not regained activity), and take a minimum of days or long...
Close to the triple point, the surface of ice is covered by a thin liquid layer (so-called quasi-liquid layer) which crucially impacts growth and melting rates. Experimental probes cannot observe the growth processes below this layer, and classical model
Incidents of viral outbreaks have increased at an alarming rate over the past decades. The most recent human coronavirus known as COVID-19 (SARS-CoV-2) has already spread around the world and shown R0 values from 2.2 to 2.68. However, the ratio between m
The moon blocks out the sun's surface in a total solar eclipse. Matt Anderson Photography / Getty Images A solar eclipse is a celestial phenomenon that does not occur very often, but they are fascinating to watch when they do. On those rare occasions when you are in the right place at...
In solids, the molecules are compact. In liquids, they're further apart. And in gases like steam they're even further apart. If you heat a can of soup in a fire, the liquid contents will vaporize and eventually expand to the point where the can will explode to release the pressure ...
