Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video! This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC B
Learn the basics about why aren't all atomic masses whole numbers? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The Fuse School. These videos can be used in a flipped classroom model o
The formulas of the salts represent ratio formulas. It describes the ratio of cations to anions. Here it is explained how to arrive at these ratios and how salt formulas can be established as a result. The naming is more of a minor matter here. Original: "Wolfgang Dukorn" Original: German. All tra
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.
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
Learn the basics about the law of the conservation of mass, when learning about properties of matter. The Law of Conservation of Mass says that in chemical reactions no matter is lost or gained. The law of conservation of mass means that during chemical change there is no loss or gain of atoms. I
We can derive expressions and equations from sentences, and also we can derive formulae such as area and volumes, or quadratics. In this video, we're going to look at deriving formulae. You are usually given information in a diagram or sentences and asked to "show that". Ignore the "show that" as th
Our sun is one reason life on Earth is possible, but what if its mass doubled? Follow Us! https://twitter.com/LifeNoggin https://facebook.com/LifeNoggin Click here to see more videos: https://alugha.com/LifeNoggin Life Noggin is a weekly animated educational series. Whether it's science, pop cul
The "law of the conservation of mass" applies! But why do all the experiments described give false results? Something has not been taken into account in these attempts. Find out what went wrong! And how could you make the last attempt so that it delivers the correct result? Original: "Wolfgang Duko
Expressions, equations, formulae and identities are all slightly different types of algebraic notation. In this video we’re going to discover the differences. An expression is a collection of letters and numbers, with no equals sign. An equation is two expressions that equal each other, and so can b
Molar mass is a chemical quantity that refers to the amount of substance. In this screencast, this is only briefly introduced and little explained. Practice is done in class! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
