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
In this video, we will look at the state symbols (s), (l), (g), and (aq) and what they represent in a chemical equation. For equations to be complete, we must also include the state symbol for each reactant and product. There are four possible states, each with their own unique state symbol. So
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
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
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
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:
In this video, we will learn how to write half equations for simple redox reactions. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners. You can both ask
The Nernst equation is used for a calculation. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
A reaction equation with molecules and salts (possibly also with metals) together is very demanding for the initial lessons. How to proceed and also how to comply with the law of conservation of mass follows in this screencast. Original: "Wolfgang Dukorn" Original: German. All translations in this
In this video we are going to look at rearranging straight line equations to find the gradient and y-intercept. Straight lines follow the equation y=mx+c, where the m is the gradient and the c is the y-intercept. But straight line equations aren’t always written out in this nice form. Sometimes we h
In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value. VISI
