Could someone give me an appropriate criticism for this?
Not that I'm aware of and, if you are writing about something obscure, and fail to explain what it is, then you are writing badly.

What does a particle actually look like - if a person wanted a realistic image of it in their head?
The spherical harmonics are not, themselves, spherically symmetrical. But the sum of the trio of P orbitals (one on each axis) is symmetrical.

It's more than that. The atom can not know what axes you chose for your coordinate system and must therefore have an shape that is independent of your choice. The only way it can do that is to be spherical.

The simple answer is that, according to our experiments, atoms are round. The case for non hydrogen-like atoms is complex, but the simple answer is that the orbitals we get have to be linear combinations of the corresponding orbitals for hydrogen (in order to meet the same momentum + energy criteria). So they look like these https://commons.wikimedia.org/wiki/File:D_orbitals.svg But what is never explained in those diagrams is that the actual sum of the functions is (So I was told as a student) spherically symmetrical.

What is the Biological Combination Theory? Origin Of Humans – How Life Started On Earth ? Where do new viruses come from ? Covid 19
No Most of what we see as science is a complex interlinked grid of theories deductions and observations. And the important thing is that they all interact successfully.

If you are going to try to be petty: get it right. It's a strontium ion. " The photo shows a pinprick of a positively charged strontium atom " If it was neutral, it wouldn't be held in an ion trap. Yes they are. Those funny looking dumbbell shapes you see are poor representations of the probability density. The actual functions sum to a spherically symmetrical distribution (unless there's one outside influence on them) But the biggest problem is this If I look at the end of my finger, what I see are photons that were emitted by virtual stated populated from the ground sates by incoming photons. The process is the same- albeit that the energy levels are different.

Why would an athiest not believe in religion?
Then I suggest that you get someone else to read your stuff before posting it. That way you might avoid saying things like "I read it twice before reading it ."

Did you read that through before you posted it?

Mold deterrent...
The MSDS lists a couple of strong alkalis as the active ingredients and those will corrode aluminium. (To be fair, so will bleach) The problem is condensation. Have you considered something like this? https://www.selfadhesive.co.uk/tapes/single-sided-tapes/foam-tapes.html

Race, IQ and Brain Size
Am I the only one who read the title of the thread and thought "that's going nowhere fast"? IQ is barely meaningful, race is barely meaningful and brain size is barely relevant.

Islands of stability in transuranic elements
And significant luck. There's no guarantee that they would be fissionable in a bomb. We simply don't know. It's possible that you could have a teeny little nuclear reactor- which would be cute, but utterly impractical.

Poison Testing
If you have symptoms which you think may be due to poisoning you should seek medical treatment. If it turns out not to be poisoning, they still need treating.

Does Hybridization Always result in superior genes?
"Does Hybridization Always result in superior genes?" It is impossible to define "superior genes" in isolation from the environment.

Ammonium Chloride
You seem strangely determined to overlook the heat gun which is odd because the importance of heating is the point of the OP's question. You can demonstrate the effect of pH on the colour of tannins by making lemon tea or, less drinkably, by adding ammonia to tea.

Ammonium Chloride
Acids are well known for catalysing the charring of carbohydrates. https://www.sciencekids.co.nz/experiments/invisibleink.html And it's a pH effect more than anything else. As you say there's no need for a heat gun

Ammonium Chloride
I presume it's this sort of thing. (The commentary is inaccurate, it' s the HCl that chars the wood rather than the ammonia.) It would probably work in an oven but I don't know if "350 degrees" wold be hot enough. Units are important. There's a risk that the HCl fumes would corrode the oven too. The HCl is very corrosive towards metals (and not very good for people either).

2nd Impeachment of a US President
- 2nd Impeachment of a US President
What worries me is that people may be leaving the party because they see it as no longer supporting their hero: Trump. OK that makes republicans unelectable which is good, but it is still terrifying that people might think that way. They might not be leaving because they recognise that the Reps are crazy; they might be leaving because use they don't think the reps are crazy enough. What happened to Rep party membership when he was selected?- Increase tall
It is probably better to buy the girl some flowers which might not work, than to buy a book that certainly won't work The authors usually rely on the fact that, when you realise you have been made a fool of, you will be too embarrassed to take them to court.- Acetic acid/water azeotropes?
No, or , at least, not at atmospheric pressure.- “I have studied these things – you have not”
There goes the neighbourhood. https://en.wikipedia.org/wiki/Edgar_Cayce#Criticism You can't cite "clairvoyants" on a science site, and expect to be taken seriously. - 2nd Impeachment of a US President
