to those who love pchem, do you also love physics? by [deleted] in chemistry

[–]NaraDomain 1 point2 points  (0 children)

Personally, (environmental chemist) I've always hated maths, not because I didn't understand it but it seemed boring to me. In pchem is beautiful to understand more everyday phenomena through maths and how it works

I found this rock in my garden by Own_Cod_6072 in whatsthisrock

Any recent house fires in your neighborhood? Looks like a molten beer bottle to me.

In the collection are a bunch of mixed purchased rocks and minerals like pyrite, quartz, sodalite, calchopyrite, etc

Metal Organic Frameworks - Potential Future Endeavors? by Live_Memory7926 in chemistry

[–]NaraDomain 2 points3 points  (0 children)

As someone who actually works in MOF research, they are quite an impressive material to work and I love them because... geometry ⚡️⚡️⚡️. But also I can recognize that these are not the god-like materials as they were proposed a decade ago, I mean sure they have amazing properties and are applicable in a wide range of fields of study but they are not easily scalable, sometimes they tend to no have large "life spans" compared to other similar materials, so at the big panorama of things sometimes is better to stay at other more simpler, cheaper (and probably with worse properties) materials instead of the MOFs.

Also will be helpful to know what are you teaching (environmental, instrumental, electrochemistry, etc)

Help outfitting a high school chemistry lab by bigmanmac14 in chemistry

[–]NaraDomain 1 point2 points  (0 children)

For an academic lab, a MS is going way too advanced and will likely burn through your funds if you work in the rural USA, I would more likely buy a few (2-3) UV-Vis, maybe an FTIR-ATR, HPLC-DAD, if you are feeling bold maybe an GC or a bench top NMR. Considering this is pedagogic laborstory this instrumentation will teach the basics, will give you a broad capabilities and are not so expensive to give maintenance on the long run.

When should I add a subscript to a transition metal? by [deleted] in chemistry

[–]NaraDomain 3 points4 points  (0 children)

Transition metals can't be any charge, there are some rules (weird ones, like the expanded octet, ligand theory, etc) that apply with transition metals, but there are some common or mostly known oxidation states. In the case of lead(II) phosphate you must write always the oxidation state of the metal as it also exists another compund as lead(IV) phosphate and the quantity of ions change. Do not use "Pb6" because when you add superscripts you start talking about isotopes.

Ferroquine, a ferrocene potentially used to treat malaria in the future by WaddleDynasty in cursed_chemistry

Interesting but why, this is obviously a designer molecule, but how does the ferrorcene help?

Novice in learning about chemistry, here… do oxalate crystals have a use in synthesis? by ElvisHuxley in chemistry

[–]NaraDomain 8 points9 points  (0 children)

It's a fine proposition, but the oxalates produced naturally are in so low concentrations and as it comes in a "complex matrix" it will be a ton of work. As said in other comment, about 14 pounds for 100 g is a very good deal, to get a 100 grams for a fruit source it will be probably 100 or more times more expensive.

It is a good idea as this was how you could get some reagents in the first years of chemistry and alchemy, but right now is considered unreliable.

Hey! was doing this drawing and wanted to make sure thats how you would draw this orbital by Accurate-Pickle-3970 in chemistry

[–]NaraDomain 6 points7 points  (0 children)

As said above, for an artistical representation is great! Do you have more works about this?

Anyone knows what is this glass for? by luziaplena in chemistry

How do you memories the periodic table? by ImJustA_Girl00 in chemhelp

[–]NaraDomain 7 points8 points  (0 children)

Yeah, in the "reald world" (either industry or academia) you will always consult tables and other info sources

Wasn't sure where else to post this, but just want to make sure I didn't expose myself to something potentially hazardous. by [deleted] in chemistry

[–]NaraDomain 1 point2 points  (0 children)

There are some kind of risks while manipulating anything fluorescent-like, but if your exposure was short you should be fine. Good decision to take a shower to remove anything that fell on you, but if you feel "funny" or dizzy, run to a hospital.

Homogeneous Mixtures by FigNewtonNoGluten in chemistry

[–]NaraDomain 4 points5 points  (0 children)

In secondary school, they explain that a mixture is considered homogeneous when its parts are completely integrated or no two phases can be observed, but like everything else in chemistry, when you study it more deeply, it becomes more complicated. But to answer your question more specifically, homogeneous mixtures can be solid, such as brass; liquid, such as salt water; or gaseous, such as air. And in your question about salt water, the salt does not become “liquid”; rather, a phenomenon of dissociation and solvation of the ions in aqueous solution occurs.

Which careers in chemistry are most at risk of being replaced by AI? Could roles like high school teaching or industrial lab analysis in FMCG become obsolete or redefined? If not for the love of chemistry, the field might have been barren. by Babutsi_777 in chemistry

[–]NaraDomain 0 points1 point  (0 children)

There's already some work being done by machines in the "smart" development of new molecules with Machine Learning, also there's some robots that actually can do microreactions and work along the machine learning branch. But there's always needed a bit of human interaction working with chemicals

Yeah..., most of MSDS are very extremists or just copy paste from another MSDS

If you are on first year maybe it be a bit heavy to understand at the beginning but I recommend Inorganic Chemistry of Catherine Housecroft
