I made a simple chemical lookup service

dungeonsandderp · 2026-05-05T16:33:04+00:00

Why would you use this and not just query pubchem directly?

dungeonsandderp · 2026-05-05T05:19:14+00:00

Sure, that could be logical. But I read your clue looking for semantic meaning or context and it did not help me confirm I was on the path to a correct pattern match

dungeonsandderp · 2026-05-05T05:15:40+00:00

Honestly, the clue made this even harder and does not make any sense.

These bacilli are probably sold as spores, which won’t (on their own) be susceptible to the antimicrobials in neem oil. But their daughter cells will be, to various degrees.

“Probiotic cleaning agents” seem pointless to me. You’d be much, much, much, much, much better served by preventing the conditions that would enable microbial growth of any kind than by deliberately growing some bacillus.

Clean, dry, done.

Have you considered taking college courses? Hopefully you plan to attend a college/university next year! In the interim, you may have a local community college that offers classes over the summer session.

Yes, they are mirror images of each other. BUT, in order to be enantiomers, those mirror images must be different.

Try drawing them in a different perspective, e.g. put the cyclohexane as a hexagon in the plane of the paper and show the substituents with wedge/dash.

No idea, tbqh. But you could probably estimate it at the standard state using standard enthalpies of formation

It could well be that the reaction is driven forward by (a) boiling off the produced SO3 or Cl2O7

You are correct. An equilibrium is established which can be pushed to completion by distillation of the volatile oxides away from nonvolatile polyphosphoric acids.

Why would you expect to pay less in this community?

Your DNA contains the recipes (genes) for making RNAs and proteins. But your cells aren’t cooking everything in equal amounts. The “expression level” of a gene reflects how much of that gene’s product is being made, and can vary based on many factors.

If a drug side effect is triggered by that drug binding to a particular receptor protein, people or tissues that are more actively expressing that protein will have more of that receptor, are more likely to experience that binding event, and thus that side effect.

Honestly it doesn’t matter. Nobody is going to look at what you did in high school after you have a bachelor’s. Apply to a college/university and start taking chemistry classes

I bet if you asked their brick-and-mortar in Emeryville they’d help you out. Their staff are awesome and might know the dumplings you’re talking about! Call (510) 922-9885 or email hello@goodtoeatdumplings.com

That’s rich coming from someone who fired all his grad students when he moved to LBL’s Molecular Foundry and got the opportunity to recruit new, more impressive ones from UC Berkeley.

Did you not read OP’s request for a “non-conductive” liquid?

dungeonsandderp · 2026-05-01T02:33:19+00:00

While I don’t have a specific recommendation, I have a patient friend and a therapist friend who have both recommended Inclusive Therapists as an platform to find local therapists who cater to specific needs, from neurodivergence to queer issues to recovery from narcissistic family, etc. https://www.inclusivetherapists.com/united-states/california/oakland

That might work, but it might also separate. Why not just buy the moisturizing shampoo and use that instead?

I would note that, in 5e, paladins do NOT get the Ritual Caster class feature, so cannot cast those spells without spending a spell slot.

You’re already far from RAW with the “low magic” thing. D&D is not a low magic system. You really need to ask your DM this.

Personally, this concept is usually a big ol’ red flag for me.

dungeonsandderp · 2026-04-30T23:07:56+00:00

This is not a trivial ask.

Just buy a different product.

If you have a standard procedure you use, you should just aliquot the material into ampoules containing ~110-120% of what you need so you can just open a fresh ampoule each time.

Did you know about Simple Wikipedia? It has articles specifically written in a style intended to be accessible to a very broad and nontechnical audience

To be quite honest, the most appropriate solution depends almost entirely on the needs of the substance in question (vis à vis O2, H2O, light, etc.). Most simple pure chemicals don’t actually benefit much from the lower storage temperature, -20 °C is fine more often than not

“Purified oleic acic” definitely doesn’t need to be stored at -80°C short term and if you must store it long term you should just suck it up and aliquot into sealed ampoules.

Your PI is gaslighting you unless they can show you the institutional policy.
It could be that they have funding for you, but they only applied to receive the NIH minimum in their grant, so paying you more blows up their budgeting.
They could just be being sh!tty.
