On the basis of an example problem, the stoichiometric calculations in chemistry are explained. It calculates the mass of a product when only a certain mass of a starting material is available. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugh
This screencast also refers to the amount of substance n. The molar volume is introduced and a mathematical formula for calculating volume is introduced. The screencast does not contain any detailed derivations or exercises! Original: "Wolfgang Dukorn" Original: German. All translations in this vi
In chemistry, substances are divided into different groups. This screencast gives a short and theoretical overview of this classification. An initial relationship between elements and compounds is essential. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been don
Polynomial division with remainder simply explained - theory, examples and calculation - math high school & university. Polynomial division requires three calculation steps: division, multiplication, subtraction. With remainder means that a number remains below the last bar. Using examples and exerc
In the event of a nuclear accident, it is important to predict the spread of the radioactivity released as quickly as possible. These forecasts are the basis for measures to protect the population. In the video, Dr. Florian Gering explains which data is included in the forecast calculations and what
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms. Chemical reactions can

Pure substances can be analysed (broken down) by chemical reactions. In the process, elements are created. The important experiment of Hoffman's decomposition apparatus is presented and the proof for hydrogen and oxygen gas is shown. The results of the experiment are part of the attendance phase at
