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.
In this screencast, the amount of substance is introduced as a basic chemical quantity. Other chemical quantities will refer to it. This screencast is the beginning of a series on chemical calculations (stoichiometry). They do not contain exercises and excessive explanations! Original: "Wolfgang D
Learn about what substance abuse is, and the consequences that result from it. Sources: https://www.drugabuse.gov/related-topics/trends-statistics https://www.summitbehavioralhealth.com/resources/articles/consequences-of-addiction/ This video was created by one of our volunteer authors to support
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
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
Radioactive substances are found everywhere in our environment. They can enter the human body through inhalation or food. In the video, Dr. Udo Gerstmann explains how to measure radioactivity in the body with a whole-body counter and when it is used. Original: "Federal Office for Radiation Protecti
There are various methods for measuring radioactivity in the air. With the help of trace analysis, even very low concentrations of radioactivity in the air can be detected. In the video, Jacqueline Bieringer explains how to detect radioactive substances in the air. Original: "Federal Office for Rad
Learn the basics about properties of ionic substances as a part of ionic bonding within properties of matter. JOIN our platform at www.fuseschool.org This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The Fuse School.
Whether furniture, clothes or toys, products we use every day contain chemicals – and some of these have properties problematic for people and the environment. In the EU REACH Regulation, these harmful chemicals are classed as SVHC - “Substances of Very High Concern”. A good way to find out if
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
In this further screencast on computing in chemistry, another difficulty is added. A mathematical formula is solved according to the quantity you are looking for. It is calculated on the basis of the relationship between mass (m) and quantity of substance (n). Original: "Wolfgang Dukorn" Original:
Using the example of the reaction between water and oxygen, the essential statements of a chemical reaction are described. What quantities of substances must be used? What does this mean for their masses? This is an introduction to stoichiometric calculations! Original: "Wolfgang Dukorn" Original:
