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
The most important functional groups (hydroxy, carbonyl, carboxy group) are presented for naming. At the end, there are simple examples of naming. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

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
Even when the limits of two functions at some point do not exist, the limit of their sum or product might still exist. Click here to see more videos: https://alugha.com/KhanAcademy View more lessons or practice this subject at: https://bit.ly/2RIVEQ8 Khan Academy is a nonprofit organization with

Every operation has an opposite. With functions the opposite is called the inverse function. It undoes the function and returns you to the initial input. There is a simple process to follow to find the inverse of any function which we look at in this video. 1) Start by writing the function as y=

Power functions simply explained graphically - positive/negative odd/even exponents & examples. The equation of a power function is f(x)=ax^n. a is the prefactor, n is an exponent. x^2 or x^4 are functions with positive even exponents, x^3 or x^5 are functions with positive odd exponents. x^-2 or x^
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
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
Do you have suspicions that you are suffering from PTSD, but are not exactly sure? Maybe you are unsure if what you went through qualifies as traumatic, or perhaps you have doubts as to whether you have PTSD because you are still able to go throughout your day and fulfil tasks and responsibilities.
