The Particle Model & the States of Matter

The particle model, the 1st atomic model, is explained. It is based on a thought experiment and describes the structure of matter and the states of matter in an easy-to-understand way. Original: "Chemistry and biology - get it!" Original: German. All translations in this video have been done by th

08 Elementary particles

This screencast is about the structure of the atoms. It is a short summary of the terms. The atomic mass "unit" is also briefly introduced. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 Chemical reactions at the particle level

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.

How do air filters work?

How do filters remove particles from the air and reduce exposure - especially the small ones? As this Risk Bites primer shows as it dives into the science of aerosol particle capture, it may not be how you think! Air filters are an important tool for protecting health, improving air quality, and

Q 11 Collision Theory

In a simple model presentation, the basic principle of chemical reactions is demonstrated. The particles must collide in the correct orientation and with the necessary energy (speed). Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 Setting up reaction equations

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

01 Arithmetic in chemistry!

This screencast discusses a simple chemical math task. Essential formalities and rules are introduced. The relationship between the number of particles (N) and the amount of substance (n) is used. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the al

Are Engineered Nanoparticles Dangerous?

We'll be tackling the risks of nanoparticles and other particles more fully when Risk Bites launches formally in November. But until then, here's a roller-coaster ride of a video on what might be important when thinking about the risks and benefits or nanoparticles - or any other particles for that
