LASC offers myriad programs that teach American English and American culture through a research-based curriculum. In our six-level English as a Second Language (ESL) program, students will build the skills and self-assurance to use English in everyday circumstances.
Find out what quarks are, how they were discovered and why they are very important in relation to protons and neutrons. There are different types of quarks which you'll learn about in this GCSE / K12 "Radioactivity" video from the Virtual School. Click here to see more videos: https://alugha.com/Fu
Acid and base definitions according to Brönsted are explained. At the end, protolysis reactions are described. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The I-effect is explained using the example of carboxylic acids. Why can some acids release their proton more easily than others? Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Why does phenol react as an acid (proton donor) even though it does not have a carboxy group? The screencast shows and explains the different mesomeries of the phenol molecule and phenolate ion. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alu
In this part 2, learn the basics about the atom, particularly about isotopes, whilst learning about properties of matter. Learn the basics about the atom, whilst learning about properties of matter. Atoms are the small bits that make up all the matter in the world around us. There are around one

Part 3 on acid-base titrations. Explanation of the indicator GGW and the calculation of the turnover area Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The law of mass action is applied to the autoprotolysis of water. Through further considerations, a constant Kw can be defined. This is called the ionic product of water. This is the basis of the pH value. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done
Paikea will be transferred from Stade near Hamburg to Hindeloopen on the Ijsselmeer, her home port this season. The 3rd leg will take her from Groningen via the Lauwersmeer, Leeuwarden and Harlingen to Hindeloopen. #sailing #sailing #hallbergrassy #north sea #hr310 #sailingintotheblues
Different isotopes of the elements can exist. These have a different mass number, but identical proton number. This is explained in the screencast and discussed again at the end using the example of hydrogen. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been do
In this video, I explain: the molecular process of translation, the function and structure of the transfer/t-RNA, the translation of the messenger/m-RNA code into an amino acid sequence, the use of the code sun to translate the m-RNA code Original: "Chemistry and biology - get it!" O
