Azido azideazide has excited a research laboratory specialising in explosive, high-nitrogen compounds. This is mostly because they detonated infrared spectrometers when they tried to measure it. When they finally got the light source to a level so low they wouldn't blow up the spectrometer, the spectrum was pretty bad. Their X-ray crystallography was apparently very good, though. N-amino azidotetrazole is our starting material. Fellow chemists in the audience, I apologise for the heart attack for having to read "azidotetrazole" and the realisation that you can make something bigger and nastier from it.

I hadn't seen it in the current thread so it may have been posted in one before now. Either way, it deserves all these mentions. Klapötke are crazy, crazy people and deserve some kind of award for all the work they're putting in to chemicals that go boom when you breathe on them from across the room.

Irradiation posted:Not super dangerous but I would sit around and sniff toluene if it wouldn't kill my brain. I love that smell. As long as you're not huffing its smaller brother, benzene. Toluene is nothing compared to straight out benzene. It's like Toluene but more effective at lower doses oh and highly carcinogenic. This is why Toluene is your aromatic solvent of choice.

Yeah, trichloromonofluromethane is pretty much your true CFC, it's pretty benign on its own but it will eat up oxygen, including ozone like nobody's business. Keep it away from fire in a well ventilated area and you'll be fine.

Yeah, unless you bathe in the stuff, DDT won't really do anything to you. Also, fun tip if you want to get rid of a trichloromonofluromethane spill? Just open the windows and let it evaporate. That's seriously the recommended spill clean advice.

Sagebrush posted:Chlorine and fluorine are quite benign and happy as long as they're bonded to something. You can eat most of the chloride salts, fluoride compounds are good for your teeth, and halogenated organic compounds are usually so stable and inert that, as noted, the clean-up method is "open a window." Or when they're attached to a hydrogen. That's bad too but that's because chlorine has a one night stand with hydrogen and gets its electron while hydrogen just kind of goes around corroding things. Fluorine does the same thing but way slower and likes bones so... Yeah. I'll say this, though. Nothing has cleared up my sinus quite like a tiny amount of HCl and DCl gas.

Goober Peas posted:I remember in the early 80s every wooden utility pole in town had a warning placard stating it had been treated with DDT and listing off the health hazards. I much prefer placards for yard sales and lost pets. It's overblown a bit, really. The only thing we've really been able to say about DDT exposure in humans is a suspected moderate carcinogenic effect and an oral dose LD50 of 113mg/kg in rats. Edit: I should also say, DDT usage is still in place, but only for severe malaria outbreaks. Intoluene has a new favorite as of 21:00 on Oct 21, 2017 |

Goober Peas posted:I mean, as far as power poles, there's always that one kid that is going to lick one That's fair, still, no way a 5 year old licking a pole would even come near a lethal dose, or hell, even one that might make them sick. That said, the carcinogenic properties might have been known and it's still prudent to notify of toxic materials. I'd be more worried about a kid eating the chipped lead paint, personally.

shalafi4 posted:I used to help clean out research labs when a prof would move/leave. Typically they'd take or hazmat most of the things before hand so most of the time the worst thing we'd deal with is a little sulfuric acid or some benzene (the benzene was immidately squirreled away to the machine shop, cleans some things way too well) The only place I'd keep Benzene is about 5 miles away from me.

Gyro Zeppeli posted:See for example: Thomas Midgley Jr, who set out to find something to reduce engine knocking, and eventually found an additive to gasoline that done the job perfectly. Tetraethyllead. Which took an astonishing amount of time (like, until the 1970s at the earliest) for people to realize cars that spew out lead are a bad idea. After becoming bedridden with polio, he used a series of ropes and pulleys to help him stay mobile. He got tangled in them and choked to death.

When we did this in high school it was just a way to have some fun getting rid of some dry ice that would just sublimate at the end of the day anyway. Plastic bottles, though. One didn't burst so we threw rocks at it. The vice principal ran down thinking something had legit detonated.

I don't know about what happens to matter inside a black hole but the two results of a person passing the event horizon are dying really quickly or dying quickly. Either there's a massive amount of energy that vaporises you instantly past the event horizon or you go through the lovely named process of sphagettification where the part closest to the black hole moves much quicker than the other parts and you become stretched out by gravity.

I tested the tap water with it in class once because I was bored. Edit: a quick search shows me that you're thinking of methyl violet. It's used more as a dye there than an actual additive. Typically methanol is used but pyridine can be used too. Intoluene has a new favorite as of 10:56 on Mar 31, 2018 |

Watching Chernobyl now, it's incredible how many of these people survived. The people who did not are very clearly not okay. The accepted number of deaths from the incident is only 31, surprisingly. The three that turned off the water system were actually fine. Two are still alive, one died in 2005 of heart failure.

Zereth posted:isn't a nucleus ejecting protons called "fission" In strict terms, radioactive decay can shave off alpha particles, too. Fission is when you split an atom in to two parts. Alpha particles and neutrons tend to result when you shear a nucleus apart. I guess if you include helium as a fissile product, Alpha decay is fission.
