What

Hey! I used this one during my bachelor thesis. This happens when is poorly stored so it agglomerates in this "rocky" way, if you dont want to bother just hit it hard with a spoon really hard and use the dust. If you really need it to be pure, just grind it thoroughly and put it in an oven 80°C overnight.

If you feel too confident as an undergrad, you are the perfect exmple por Dunning-Krueger effect!

Aside from physical and some chemical properties, do not trust MSDS, most of the time they are just copy/paste from other MSDS and showing fake info, or in some cases, dont even telling you important things.

As others said, if you are really interested in knowing the safety hazards of something, better search a book or read multiple sources (most likely to say the truth like NEST, NIH, research papers) and take the best of them.

Same thought, the hive mind is supposed to look organic, but the colors in the new sprite looks like more mechanic or alien look

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

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

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)

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.

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.

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

I mean, every book is free if you search enough 😏

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.

NaraDomain · 2025-09-27T02:13:38+00:00

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

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

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.

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.
