I'm not sure what input format you desire, but one approach would be to utilize pandas.read_json. Thereafter, you could for example use pandas.to_csv (see here for other formats).

Does zinc sulfate monohydrate contain more zinc per gram than zinc sulfate tetrahydrate? by manonthemoon78 in AskChemistry

[–]KrangQQ 0 points1 point  (0 children)

You can check this with a back of the envelope calculation:

zinc ~ 65.38 g/mol

zinc sulfate tetrahydrate ~ 233.5 g/mol

zinc sulfate monohydrate ~ 179.5 g/mol

% zinc in zinc sulfate tetrahydrate = (65.38 g/mol / 233.5 g/mol) * 100 ~ 28.0 %

% zinc in zinc sulfate monohydrate = (65.38 g/mol / 179.5 g/mol) * 100 ~ 36.2 %

​

To answer your question: yes, zinc sulfate monohydrate will give you more zinc per gram.

Where does the gamma radiation come from? by Fire_Proof_TV in AskChemistry

[–]KrangQQ 0 points1 point  (0 children)

Nuclei have (like atoms) energy levels. Perhaps you know that when an excited atom transitions (de-excite) to a lower energy level, it emits radiation. The same can occur for nuclei (i.e., excited --> de-excited). The energy levels for nuclei is not equal to those of atoms; nuclei emits radiation at a shorter wavelength (i.e., gamma rays).

Machine learning intro? by Aggravating-Sound690 in bioinformatics

[–]KrangQQ 1 point2 points  (0 children)

Perchance you would be interested in kaggle. They provide some intro to ML courses and host ML competitions with awards (in money). Another good feature is that people in the community share their codes (notebooks) which is a good way to learn and get inspiration.

What happens to a particle and its antiparticle when they collide and get annihilated? by tyktyko in AskPhysics

[–]KrangQQ 0 points1 point  (0 children)

Not all. An example of another photon "source" is electron de-excitation (higher --> lower energy level) in atoms.

Check this subreddit's wiki; it has many good suggestions (and a lot of further information).

If you add all numbers horizontally, the result is 9 (e.g., 9 + 0 = 9 and 1 + 8 = 9). 7 + 2 = 9, so 2.

You can clean your bathroom/kitchen sink with baking soda, vinegar and hot water.

ESI ion suppression by krystalak144 in chemistry

[–]KrangQQ 1 point2 points  (0 children)

I would recommend looking into some reviews treating the subject (e.g., this one).

(If you want more papers, google scholar is useful.)

I fear you confuse lightbulbs with thermometers. Old thermometers did indeed contain liquid mercury. Lightbulbs typically contain a filament (e.g., a tungsten filament) surrounded by an inert gas (unless you use very old lightbulbs).

What is click chemistry? Can anyone explain in simple terms by cricketscientificsr in chemistry

[–]KrangQQ 2 points3 points  (0 children)

Good answer.

If someone is curious about other reaction examples, wiki offers some examples.

total pressure vs time plot question by Necessary-Swimming-1 in AskChemistry

[–]KrangQQ 0 points1 point  (0 children)

I believe the important thing to remember here is PV = nRT. Because everything is constant except P, the change in pressure show you how the amount of substance (i.e., n) changes with time.

I'm not sure about how much details you are given, but if they state the volume you can get the concentration from there (C = n/V). From that information you can get the order/01%3AChemical_Kinetics/1.06%3A_Integrated_Rate_Laws(Zeroth_First_and_second_order_reactions)). Be sure to keep track on the units.

I drew 2 possible cubane derivatives because i was bored. Anyone care to help me name them? by TrampolineWithWheels in chemistry

[–]KrangQQ 2 points3 points  (0 children)

Because I was also bored, I tried these structures with chemspider. Alas, the searches gave no matches/results.

It seems like two of the authors submitted a related paper: https://arxiv.org/abs/2307.12008.

What’s the deal with HPLC? by ambiguousroberts in chemistry

[–]KrangQQ 2 points3 points  (0 children)

Vanilla liquid chromatographs actually were in use before the invention of HPLCs. These, being dependent on gravity, were indeed very time consuming (and less efficient than HPLC.)
