Large stars die, and then explode into massive supernovae. This scatters all the elements of the periodic table throughout the Universe, which results in the third threshold of complexity -- the creation of chemical elements. Website: https://www.bighistoryproject.com/portal Facebook: https://www.f
How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
Learn the basics about How the elements are laid out in the periodic table? Why are they all named and placed that way? Find out more in this video! Click here to see more videos: https://alugha.com/FuseSchool This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
In the periodic table there are a lot of element symbols with different numbers. The most important ones are explained and how they can be used to infer the structure of the corresponding atom. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugh
Sodium reacts with chlorine to form a white salt, sodium chloride. An ionic bond of cations and anions is formed. It is explained how the PSE helps to determine the charges of the ions and to establish the ratio formula from them. Original: "Wolfgang Dukorn" Original: German. All translations in t
Learn the basics about testing alkenes with bromine water. Why is bromine water used to test alkenes? What is bromine water made of? Find out more in this video! This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY-NC ( View License Dee
The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b
Fusion, which occurs when atomic nuclei combine to form new elements, is extremely powerful. All the stars in the universe, including the Sun, are nuclear furnaces fueled by fusion. Through fusion, stars are responsible for forming all the naturally occurring elements heavier than hydrogen and heliu
Chemists always distinguish between the macroscopic and microscopic level. What does that mean? In the experiment zinc reacts with sulphur, this level is attempted to be demonstrated. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Learn the basics about Indicators, more specifically for acid and bases. An indicator is a large organic molecule that works somewhat like a " color dye". Find out more in this video! This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY
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
