08 Naming of Molecules
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.
08 The Electron Pair Bond - Molecules
Molecules are compounds of non-metal atoms. But how does the bond come about? They cannot give up or absorb electrons completely, because both partners want to have more. Using the fluorine molecule as an example, the electron pair bond is explained with the help of the energy level diagram. Origin
09 Spatial structure of molecules
The spatial structure of the most important molecules is explained and then practiced. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
08 Reaction Equations Molecules and Salts
A reaction equation with molecules and salts (possibly also with metals) together is very demanding for the initial lessons. How to proceed and also how to comply with the law of conservation of mass follows in this screencast. Original: "Wolfgang Dukorn" Original: German. All translations in this
10 Hydrogen bonds of organic molecules
The hydrogen bonds among alcohol molecules are explained and compared with carbonyl compounds. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The Effect of Sea Surface Temperature on Hurricanes
This video segment adapted from NOVA scienceNOW highlights research that supports the idea that warmer oceans generate and sustain more intense hurricanes. Ongoing monitoring of sea surface temperature (SST) has supplied evidence that the world's oceans warmed 0.5°C between 1970 and 2005. Because hu
10 boiling points in general and for hydrocarbons
The boiling temperatures of the hydrocarbons are explained. A short review of the basics is at the beginning. The influence of the molecular surface on the boiling temperatures is also explained. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alu
08 The molecular formula
Ha two O! This is the spoken formula of water. What does this mean and how can it be applied to other molecules? This screencast is about the formula notation of molecules. It is not a question of why the molecules in question are built the way they are. Original: "Wolfgang Dukorn" Original: Germa
How is wind created?
When air is in motion, wind is created. Temperature differences are responsible for this. When air warms up, it rises and colder air flows in. This is the cool wind that we feel. There is almost always wind on the coasts. Author: ZDF/Pur+/Autorenkombinat/Tobias Schönke/Carina Schulz/Jochen Schmidt
Avogadro's Number - The Mole | Chemical Calculations | Chemistry | FuseSchool
Learn the basics about Avogadro's number - The Mole. What is Avogrado's number? Why is it called like that and what relation does it have to the mole? Find more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation
10 Polarization in electrophilic addition
The step of polarization repeatedly causes difficulties in understanding. For this reason, this screencast is intended for classroom follow-up and only illustrates the step of polarization of the bromine molecule by ethylene. Original: "Wolfgang Dukorn" Original: German. All translations in this v
