In this video we look at the basics of algebra, focusing on the notation that is used. In algebra we use symbols to represent numbers. These symbols are called variables. Some reasons for using symbols instead of numbers is that the symbols, or variables, can represent unknown quantities and for s

Applying the energy levels all the time takes far too long. Therefore, a simple shorthand notation of the electron configuration was developed. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Material quantity ratios can be formulated in very different ways. However, there are more skillful and clumsy ones. This screencast explains how to make it a little easier for yourself. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
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
Salts are formed from the reaction of their elements. It is explained how the electron release, electron uptake and the overall reaction are to be formulated. In order to be able to formulate the redox reactions later, this type of reaction is very important! Original: "Wolfgang Dukorn" Original:
Skeletal structure - representation of organic compounds simply explained - substances and particles - organic chemistry. The skeletal structure represents organic compounds more clearly, simply and faster. In this context, important basic terms are line-angle formula or structural formula and valen
The valence stroke formulas, or Lewis formulas, are explained and practiced with some examples. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
In this video we are going to look at how to do calculations with standard form. When adding and subtracting numbers in standard form, we need to write the numbers out into ordinary numbers, do the sum and then turn the answer back into standard form. With multiplication and division we can work
The oxidation of the primary and secondary alcohols by the oxidizing agents potassium dichromate and potassium permanganate is explained. Redox reactions are formulated. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The screencast shows how to formulate reaction equations in the chemical formula language. The law of conservation of mass is fundamental and is evident both at the particle level and in the reaction equation. Afterwards it is necessary to practice a lot! Original: "Wolfgang Dukorn" Original: Germ
In Germany, around 1000 crop protection products are registered - such as insecticides or fungicides. A plant protection product consists of a toxic active ingredient and an often toxic co-formulant that makes the product water-soluble, for example. Author: 3sat/nano/DokUtopia Film/Berndt Welz/Seba
