Fluorine is known as the most powerful oxidizing agent out of all the elements in fact, it's so reactive that it turns water into oxygen on contact. I have to say, not being used to this sort of chemistry, that if I saw these events going on in my fume hood that a series of slight explosions might well take place beneath my iron breastplate. F00F is also a division bug in intel CPUs of the Pentium class, and dates from 1997. Put those in a warhead" and "what would happen if you used this stuff in a mine field, assuming some unobtainium even it couldn't react with?". Yes, at hundreds of degrees below zero, this stuff sets ice on fire. There are only a few chemicals which. Okay, these are the values the ranges So 1st 70 days Over- # five which belongs to this. All rights reserved. Meaning its capable of rapidly oxidizing things that would normally be considered practically impossible to set aflame, like asbestos. Learn more about Stack Overflow the company, and our products. It is apparently about the most vigorous fluorinating agent known, and is much more difficult to handle than fluorine gas. First discovered back in the 1930s, chlorine trifluoride is a rather curious chemical that easily reacts, sometimes explosively, with just about every known substance on Earth. Chlorine trifluoride appears as a colorless gas or green liquid with a pungent odor. It will also ignite the ashes of materials that have already been burned in oxygen. The stuff could be used as an incredibly effective chemical weapon that was also cheap to produce. All rights reserved. Manage your stress with a perfect tune backed by science. Fe+3 then reacts with OH- of water forming Fe(OH)3 a brown ppt and H+ of water reacts with the remaining Cl- to make the aqueous solution acidic by forming HCl. The most extensive work appears to have been done in the 1960s by a certain A. G. Streng working at Temple University. So the obvious solution is to drop a machine producing ClF3 upon your enemy. Pure ClF3 is stable to 180C (356F) in quartz vessels; above this temperature, it decomposes by a free radical mechanism to its constituent elements. But if you start talkin' chlorine trifluoride, we'll take a hard pass, thanks. A sample:"If small pieces of yellow phosphorus be added, with stirring, to a solution of chlorine azide in carbon tetrachloride at 0C, the solution gradually becomes turbid, and a succession of slight explosions takes place beneath the liquid. ut eget leo id, massa felis diam quis, vulputate, Donec. Chlorine monofluoride It offered improved specific impulse over chlorine trifluoride, but with all of the same difficulties in handling. Its been used in the semiconductor industry to clean oxides off of surfaces, at which activity it no doubt excels. Obviously the first question to answer here is how chlorine trifluoride is somehow able to cause asbestos, a substance that is known for being almost completely fire retardant, to catch on fire. ), and on, and on. They isolated the compound chlorine trifluoride (ClF3), which was liquid (check!) And if anyone needs any more proof as to why, I present this video, made at some point by some French lunatics. in tempus justo mattis vel, tristique porta. In realistic space combat, objects are enormously far away (requiring guidance, not mortars), and are traveling so enormously fast that the kinetic energy is all you need to make a kill. Let's look at some of the worst-case scenarios for using this thing in space: The Nazis tried to see if it could be weaponized in the years leading to World War II. However, a few experimenters have had a go with dioxygen difluoride and survived. As a liquid, the substance is decidedly more threatening looking, taking on the form of a pale green substance. He has curated a horrific collection of nasty poisonous reagents from his own field of organic chemistry, alongside a hellish collection selected from other specializations. There's something really, really big in the middle of our Milky Way galaxy one of the largest structures ever observed in the region, in fact. No leather suits this time and (interestingly) no earplugs. Chlorine trifluoride is prepared by the reaction Cl2 (g) + 3F2 (g)2ClF3 (g). . You may observe the mild reactivity of this gentle substance as it encounters various common laboratory materials, and draw your own conclusions. On a review of the literature, Lowe notes that the vast majority of the work has been theoretical, which seems sensible. . Chlorine trifluoride ( 01:17) Let's start with what the Germans had in that secret weapons bunker. Chlorine trifluoride has been investigated as a high-performance storable oxidizer in rocket propellant systems. It is corrosive to metals and tissue. (Actually, the other runs probably yielded that, too, albeit as a fine haze). You have to coax it into existence, and even then it threatens to non-exist and you alongside it. Higher exposures can cause a build-up of fluid in the . Answer by Paul Mainwood, Degrees in Physics and Philosophy, Doctorate in Philosophy of Physics, on Quora: I dropped organic chemistry as soon as I could. Chlorine trifluoride is very unstable so it's energetically favourable to react with almost anything to produce more stable fluorides; releasing oxygen, chlorine and compounds of the two. "Do not be omitting the stirring, then. @StianYttervik, while true that a portion of my answer assumes the simple mixing of chemicals, it doesn't change the fact that the creation of ClF3 is nothing more than a process. This will be accomplished by mounting your copper vessel in a magnetically accelerated slug or self-propelled missile. We have Plexiglas, a rubber glove, clean leather, not-so-clean leather, a gas mask, a piece of wood, and a wet glove. But another nice thing about this paper is the way some parts of it are written, in a style which was a bit formal and archaic even for 1943. . This colorless, poisonous, corrosive, and extremely reactive gas condenses to a pale-greenish yellow liquid, the form in which it is most often sold (pressurized at room temperature). Gases can cause rapid suffocation because of oxygen deficiency; store . Language links are at the top of the page across from the title. Answer (1 of 4): CHAOS LEVEL 10!! Q&A for work. It burned its way through a foot of concrete floor and chewed up another meter of sand and gravel beneath, completing a day that Im sure no one involved ever forgot. This question originally appeared on Quora. Sure, it can kill people and destroy equipment. Build the largest LEGO Millennium Falcon to dateIncludes two crews of minifigures - 4 classic crew minifigures: Han Solo, Chewbacca, Princess Leia and C-3PO, plus 3 Star Wars Episode VII/VIII crew minifigures: Older Han Solo, Rey and Finn. An average 70 kg human being only would have to take around 100 nanograms of this protein to die (it has an LD 50 of 1. . 13(b-1) which was obviously different from that shown in Fig. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. It reacts with water to form chlorine and hydrofluoric acid with release of heat. All rights reserved. Or it's used intentionally as a nasty disgusting weapon that people normally don't use to shock the enemy. Unsurprisingly, the Nazis were really interested in the military applications of chlorine trifluoride. Powered by Tumblr. This stuff was designed from the foundation of the universe to fulfill that trope! Overall, there is little to gain from conventional munitions with this approach. @JBH highly reactive and highly explosive substances are useful as weapons because they essentially contain large, concentrated amount of available chemical energy that can be delivered upon the target. ClF3 will quickly corrode even noble metals like iridium, platinum, or gold, oxidizing them to chlorides and fluorides. Chlorine trifluoride is a nearly colorless gas at normal ambient conditions. This is a concept invented by the American meteorologist. 13(a-1), by visual inspection. It will not only set water on fire, but water makes it explode. Get our latest posts and insights delivered directly to your inbox. Chemical Properties. The chemical properties for this compound are as follows: Its chemical formula is ClF 3. Scientists in China Discover Rare Moon Crystal that Could Power Earth, When Well Know if NASAs Asteroid Impact Test was a Success, What Screaming Black Holes are Telling Us, The First Native American Woman Travels into Space with NASA's Crew-5 Mission. . As a solid, its white. It's the things around them that alter. FOOF is the sound you make when you make some FOOF. The compound causes severe irritation to mucous membranes, eyes, and skin, and on exposure to the Chlorine Trifluoride gas, it can cause lung damage. But chlorine azide has not been weaponized, nor will it be. A few of the other things known to not react with chlorine trifluoride include nitrogen, the inert gases and polychlorotrifluoroethylene. I am reviewing a very bad paper - do I have to be nice? On making them fall for it, they will gather their top chemists, materials scientists, top engineers and technicians in on place with what is the most uncontrollable, uncontainable, volatile, corrosive, poisonous substance a deranged chemist ever came up with. It is shipped as a greenish-yellow liquid. Its been used in the semiconductor industry to clean oxides off of surfaces, at which activity it no doubt excels. @ozone - it's false. But even A. G. Streng chickened out of reacting it with sulfides. You may observe the mild reactivity of this gentle substance as it encounters various common laboratory materials, and draw your own conclusions. For dealing with this situation, I have always recommended a good pair of running shoes.[17]. Maybe a kamikaze run? The end result of their research was the gaseous form of Chlorine trifluoride. Chlorine trifluoride, an interhalogen with the formula ClF 3, is all of these things and more. T-shaped molecular geometry. Even an indirect hit in the right spot could be . .masks and breast-plates of sheet iron worn by observers during times of danger. As if that wasnt worrying enough, if youre ever unlucky enough to get hydrofluric acid on your skin, it doesnt actually hurt until a few hours later. Would Chlorosian photosynthesizers produce chlorine or oxygen? . It turns out that combining them into chlorine trifluoride makes them much worse. Never work on a pressurized system. Rather fortunately, chlorine trifluoride doesnt react with air unless it happens to contain a larger than average amount of water vapor. Sand Won't Save You This Time (the prequel to Chlorine Trifluoride: Some Empirical Findings) is also worth the read. within the immediate work area for emergency use where there is a . Sound advice, indeed. [F-].F [Cl++] Reacts with benzene, toluene, ether, alcohol, acetic acid, selenium tetrafluoride, nitric acid, sulfuric acid, alkali, hexane. If your shell is too weak to get through the hull, it would splash against the armor, react with a small amount of the hull material, be explosively ejected by its own reactive byproducts, and disperse into the vacuum of space with minor damage done. The circle below shows a mixture of hydrogen sulfide gas and oxygen gas, which react form sulfur dioxide and water. Although scores of violent detonations have occurred, with resultant demolition of much apparatus, no personal injury has been suffered. How to intersect two lines that are not touching. Asteroid Ryugu Has Dust Grains Older Than the Sun. Oxygen, hydrogen peroxide, and the halogens are common examples of these agents. . So I thought today I'd step back to a period when men were men and chlorine azide was a reactive, toxic, and unstable compound that was only good for finding out what sort of explosion it would set off next. Reichsmark exchange rate values from 1942 to 1944 are fragmentary. (The list of people who were blown up and poisoned while trying to do so is impressive). Untitled - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Boils at 53F. You may observe the mild reactivity of this gentle substance as it encounters various common laboratory materials, and draw your own conclusions. The extremely rare blood type is shared by only a handful of people on Earth. An explanation of the molecular geometry for the ClF3 (Chlorine trifluoride) including a description of the ClF3 bond angles. Lets look at a couple: First, Dr. Lowe was musing on the ever-present sand-bucket in the corner of chemistry labs, and wondered if there was anything that if dumped in there would just set the sand on fire. (An indexing machine is a rotating assembly with work-holders around its periphery that advances the work in steps through a series of stations followed by a pause during which operations at each station are carried out on the Page 12 of 31 Handbook of Advanced Lighting Technology DOI 10.1007/978-3-319-00295-8_1-1 # Springer International . Here is a chemistry tip. ), perchloryl fluoride (! Kecuali dinyatakan lain, data di atas berlaku pada temperatur dan tekanan standar (25 C [77 F], 100 kPa). Learn more about Teams . Yes, that stuff that is famously fire-retar Really, how often have we heard the "but mutagenic weapons have been banned by all civilized species!" For dealing with this situation, I have always recommended a good pair of running shoes.. In contrary to chlorine, it would not damage biological tissues. In an industrial accident, a spill of 900 kg of chlo. They originally planned to produce 90 tons of the stuff every month, but only made about 30 tons throughout the whole war. Neither compound has been used in any operational rocket propulsion system. It happens every fall in October or early November, and peak viewing hours are coming soon to skies near you. Applying Super Glue (cyanoacrylate) to cotton or wool results in a rapid chemical reaction that releases enough heat to cause minor burns, so typically this should be avoided. This will be determined by the number of atoms and lone pairs attached to the central atom.If you are trying to find the electron geometry for ClF3 we would expect it to be Trigonal bipyramidal.Helpful Resources: How to Draw Lewis Structures: https://youtu.be/1ZlnzyHahvo Molecular Geometry and VSEPR Explained: https://youtu.be/Moj85zwdULg Molecular Geo App: https://phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.htmlGet more chemistry help at http://www.breslyn.orgDrawing/writing done in InkScape. To anyone asking why anyone would be so idiotic, Dr. Lowe is with you: Elemental fluorine has commanded respect since well before anyone managed to isolate it, a process that took a good fifty years to work out in the 1800s. The problem with that idea is how dangerous this substance is to create and work with. Chlorine pentafluoride (ClF5) has also been investigated as a potential rocket oxidizer. [16] Unlike most of the alternative chemicals used in this role, it does not need to be activated by the use of plasma since the heat of the chamber is sufficient to make it decompose and react with the semiconductor material.[16]. Sight, hearing, touch, smell, and taste can all be affected, diminishing their experience of the world. Use Raster Layer as a Mask over a polygon in QGIS, How small stars help with planet formation. It is corrosive to metals and tissue. Storing it aboard your spaceship is too risky, sure, as other answers have noted. one is included true how it is say theater equal to one by to say theater doesn't belong to this interval so this is incorrect. In the 1930s, scientists Otto Ruff and H. Krug set out to find something easier to handle, but just as reactive. It only takes a minute to sign up. The real question is whether it's all worth using. the place to gain and share knowledge, empowering people to learn from others and better understand the world. Nope, it's straight to the Iron Man look. Even the nukes do their job via a nuclear reaction, but that reaction isn't run at our military bases, ships or planes; a projectile starting that reaction when it arrives is used as a weapon instead. If you've seen a shooting star on a recent stargazing jaunt, you've spotted the very beginning of the Orionids meteor shower. Pretty cool article either way. Reactions with many metals give chlorides and fluorides. Image by Ken Wilcox under Creative Commons license. The molecular geometry of ClF3 is approximately T-shaped, with one short bond (1.598) and two long bonds (1.698). It seems that no-one has done so (or at least, no-one has done so and survived in a state to write a paper about it). IDLH Value: 12 ppm (45 mg/m3) Basis for IDLH Value: The IDLH value for chlorine trifluoride (CIF3) is based on data on eye irritation in rats exposed at a concentration of 480 ppm for 5 minutes, which was determined to be escape-impairing [Horn and. The shell would have to detonate in the middle of the ship for maximum effect. 2023 American Association for the Advancement of Science. It is hypergolic with" (that is, it explodes in contact with) "every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. The greatest danger I can think of for my ships crew is they will be distracted by their hysterical laughter once they realize what you shot at them. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water with which it reacts explosively. The elongated Cl-F axial bonds are consistent with hypervalent bonding. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. Chlorine trifluoride is one of the most horrifying substances on Earth. The union one twin thing. This creates a thin fluoride layer inside the container, which won't disturb the CIF3. Further, there is really little one can do to put out the fires it causes directly other than to let them burn off. This was a huge mistake, and one that I might have avoided if I could have read Derek Lowes posts to Science Translational Medicine. only a scrap of plan/data left). The only known way to store chlorine trifluoride safely, which we use in the loosest possible sense, is to put it inside of a sealed containers made of steel, iron, nickel or copper which are able to contain the chemical safely if theyre first treated with flourine gas. What is the hardest part of being a scientist. ut non et, dapibus. What are possible reasons a sound may be continually clicking (low amplitude, no sudden changes in amplitude), Storing configuration directly in the executable, with no external config files. But it can also kill the people trying to use it as a weapon. This is what you get when you run oxygen and fluorine through a 700C heating block. What screws can be used with Aluminum windows? But they were made of sterner stuff back in 1943.The date does make me wonder if there was war research money involved; I wouldn't be surprised. Of all the dangerous chemical gases, chlorine trifluoride is known to be the most flammable. This suggests that the stuff might be better used by a saboteur or terrorist. It burned its way through a foot of concrete floor and chewed up another meter of sand and gravel beneath, completing a day that Im sure no one involved ever forgot. But using sword-chucks during WW2 won't do anything useful. The most spontaneously reactive species are usually not spontaneously produced themselves.
