The most important functional groups (hydroxy, carbonyl, carboxy group) are presented for naming. At the end, there are simple examples of naming. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
The priorities of the different functional groups (hydroxy, carbonyl and carboxy groups) are explained. The following are examples of naming. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
From the molecular formula to the molecule name. What is carbon tetrachloride? Can you infer the molecular formula from the name? Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Sodium reacts with chlorine to form a white salt, sodium chloride. An ionic bond of cations and anions is formed. It is explained how the PSE helps to determine the charges of the ions and to establish the ratio formula from them. Original: "Wolfgang Dukorn" Original: German. All translations in t
How are simple hydrocarbons named? The international rules for alkanes are briefly explained here. You can also do the examples as an exercise. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Some molecules are presented and then named. This screencast can be used for practice by always stopping in time. Of course, you can also have everything explained to you again. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Formation of sodium chloride from the elements. The various energies that are applied and released are shown and briefly discussed. An exact quantitative consideration does not take place. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Rutherford's atomic model can already explain a simple formation of charged particles (ions). The PSE can help us detect whether an atom absorbs or releases electrons. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Large stars die, and then explode into massive supernovae. This scatters all the elements of the periodic table throughout the Universe, which results in the third threshold of complexity -- the creation of chemical elements. Website: https://www.bighistoryproject.com/portal Facebook: https://www.f
Discover how the James Webb Space Telescope will help us better understand solar system formation in this video from NASA. Images from the Hubble Space Telescope show star-forming regions within the Eagle nebula: visible light images show vast clouds of gas and dust, and infrared images provide a gl
