The electronegative value of hydrogen is $ 2.1 $ , while the electronegative value of sulphur is $ 2.5 $ . $ H - S $ bonds are characterised as non-polar since the difference between these two values is smaller than $ 0.5 $ . The entire molecule of hydrogen sulphide i...

(the hydrophilic part) forms the outer surface of the micelle and is exposed to water. The lipophilic portion of the molecule (which is hydrophobic) is shielded from the water. Anyoils in the mixture are isolatedwithin the interior of the micelle. Hydrogen bonds stabilize the hydrocarbon chains...
While the idea of dipping into wintry waters may disturb your thermal comfort, many people subscribe to polar-bear-like behavior in the name of health. And the cold, hard evidence has been trending on your social feeds, where athletes and influencers document their icy water-bath challenges. ...
In fact, there still is, as Mars is one of the planets with polar ice caps, which are largely composed of frozen water. However, it has long been believed that liquid water vanished from Mars at least two billion years ago. A recent study on the Lafayette Meteorite has thrown this ...
What are lipids? Organic compound An organic compound refers to the formation of bonds between carbon and another element, generally hydrogen or a pair of the same type (carbon). The presence of other elements such as oxygen, nitrogen, sulfur, phosphorus and other elements are also frequent in...
