Back in 60's when I was a kid (around 10 years old), my friends and I would ride our bikes to the drug store and buy bottles of ammonium dichromate. Big bottles of the stuff. After a few purchases, the pharmacist finally asked, “what in the world are you kids doing with all this ammonium dichromate anyway?” Oh, we're just making ammonium dichromate volcanos in our back yard. The pharmacist shrugged his shoulders, looked at us directly and warned us to be careful. We were careful and no one got hurt. And that how things went back the day for kids from Lake Wobegon.

Yea, The pharmacist that owned the pharmacy I did my residency at talked about all the cool things you used to be able to do. Mostly explosives. Until they cracked a window with their black powder, and his mum put a stop to it. We used to do random chemistry 'recipes' from the 18th century 'useful household things' ranging from fireworks to glue to pesticides.

@SpritoftheStairwell6 жыл бұрын
The simplest answer to why they are arranged in such a way is the valence shells of the elements. The s-block (groups I and II) have s-orbitals as their valence (outermost) shells, the p-block (main group) elements have p-orbitals as their valence shell, and transition metals have d-orbitals as their valence shells. The number of electrons that can go into the d-orbitals and their various energy levels are what cause them to have unique reactivity.

You don't really learn anything from these videos. You have to have a basic understanding of whats going on to understand the reactions, enough to where you wouldn't be learning anything new, you'd just be seeing something happen that you already know will happen. If you don't know enough to understand the reactions, you won't know it from watching the video considering nothing about it is actually mentioned as these are beginner oriented novelty videos not educational videos, you'd need to spend a long time studying reaction pathways in an actual classroom before it could make any real sense.

Professor, two weeks ago I witnessed the brightest meteor I've ever seen. So intense that I cast a dim shadow as it passed. It was the most amazing pale green. I know this might be more of a astrophyisics question, but I wondered what chemical makeup would show a color like that. Another factor was that it looked like it just skipped off the upper atmosphere, so maybe it was burning yellow and was "greened"" though our blue tinged atmosphere, so green and yellow could have been the real colors as it burned.

Chromium, aka chrome, is still used for some corrosion protection/looks on the outsides of brass valves, where stainless cannot be used because of chemical reaction. It is also used for industrial applications where wear resistance and very tight tolerances are needed. The chrome plating can be applied in very precise thicknesses, increased flatness of a surface and improved surface finish. For this use, it is not polished to the high luster you’d expect from chrome, so a part may chromed and you wouldn’t ever know. With more precise alloys and machining methods, these uses are also going the way of the horse...

The reaction at 6:30 forms a violet peroxo complex of chromium, thought to be [CrO(O2)2(OH)]- if I recall correctly, not two different compounds as stated. This then decomposes to oxygen gas and is reduced to green Cr(III). The peroxo complexes of chromium are awesome and you should make a video dedicated to them in the future!

One thing that is really underappreciated about chromium is the lower oxidation states of chromium, mostly chromium(III) for its beautiful color (mostly in various purple-violet hues) and stable complexes, and rich inorganic chemistry (catalysts, photochemistry). And also the more exotic species like the quadruple-bond forming chromium(II), and the negative oxidation state when bonded with carbon monoxide.
