exothermic reactions

“Chemistry”

Pairing: Bucky Barnes x Reader (College AU)

Summary: In which Bucky attempts to use chemistry to explain the chemistry between you and him.

soundtrack:
“Unholy War” (Jacob Banks)

A/N: any chem talk was me attempting to remember things from chem class in senior secondary school. forgive me if i made any mistakes! -j. x

“Are you annoyed?”

“… Oh, I don’t know, Bucky, what do you think? What do you think my problem is?”

“Um, it’s a Friday night and you’re here in the lab instead of somewhere else?”

Your problem isn’t the fact that you’re stuck in a lab on a Friday night. You’re annoyed because for some reason, Bucky Barnes has followed you into the lab and refuses to leave. He’s now poking your upper back like he’s a prepubescent teenager who just discovered the poking feature on Facebook.

Your apartment mate Steve introduced you to Bucky last semester. Apparently a few interactions and that one time you helped him with a Chem 101 problem set was enough for Bucky to decide that you two should be a couple.

Oh yes, sparks did fly, but that’s because Bucky’s personality borders on the line of flirtation. As cute as he is, you’ve brushed away his “declarations” of love. You know how guys like Bucky work, and their agenda isn’t something you want to get involved in.  When you find yourself getting too entranced by his chivalry and wit, you remind yourself to tread carefully. Much to your annoyance, your rejections have no effect on his persistence.

Forehead creased in frustration, you grab Bucky’s offending finger before staring into his blue eyes. “Please stop,” you let out.

Bucky hops onto the surface of a lab desk. Kicking his legs up and down, he lazily smirks at you as he watches your eyes drift from his eyes to the rest of his body. “You like what you see?” Bucky cheekily asks. “Take a picture, doll face. It lasts longer.”

Doing reactions at -78.5 °C using Dry Ice. 

Dry ice is the solid form of carbon dioxide that sublimates at −78.5 °C (−109.3 °F) at atmospheric pressure. This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite).

If a fast or quite exothermic reaction is being performed, the really low temperature often helps a lot. It prevents runaway of the reaction and keeps chemistry in the flask. In my case a fluorinated compound was reduced with a complex metal hydride. At room temperature the reduction happens and gives a side product, if it’s cooled with ice or salt-ice bath a maximum 40% yield could be achieved, but if it’s being performed a -78 °C up to 90% product could be isolated on a 200 g scale. 

anonymous asked:

Hey Mum :) might you at some point be able to fic college Alex pulling an all nighter and Maggie looking after them/putting them to bed/checking on them afterwards, please? It's been a rough term.

If they were anyone else, they wouldn’t feel the need to pull an all-nighter.

If they were anyone else, they would have deemed that they’d studied enough, that they deserve a break, that they’d reached their limit and that they needed sleep, or at least time with friends or Netflix.

But Alex Danvers is not anyone else.

So they settle into the dorm’s study room so they don’t keep Lucy up in their own room, and they completely take over the long table with notes, with textbooks, with scrambled calculations and their glasses case and their granola bar wrappers.

They don’t notice when the door opens behind them because they’re muttering about exothermic reactions and the possibility of harnessing the energy created to –

“Delivery for Dr. Danvers,” a soft voice behind them makes them jump before smiling tiredly.

They turn and their girlfriend is behind them, decked out in reindeer pajama pants and a tank top that perfectly highlights her arm muscles, holding out a bag with a couple slices of pizza and a latte.

“Pfft, I’m not a doctor yet,” Alex splutters, and Maggie sets the pizza down on one of the only clear spaces on the table and presses the latte into Alex’s hands along with a kiss to their lips.

“Might as well be, Danvers, the amount of shit you know that even our professors can’t keep up with. What’s the game tonight?” she asks, her hand lingering on Alex’s waist as she turns to rifle through some of their papers, making sure to keep them all in the order Alex has them in.

“I can’t crack the formula I need, and I wanted to have it all squared away before the presentations tomorrow.”

They run their hand through their hair and moan with relief as they sip at the latte, and Maggie has to forcibly restrain herself from not lunging at Alex and taking them then and there.

She knows there’s no point in reminding Alex that the presentations are meant as progress updates, not finished products, because she knows that the call Alex will inevitably get tomorrow afternoon from Eliza asking how it went will send them into a spiral if they can’t report at least somewhat adequate progress by her standards.

Hell, the call will probably send them into a spiral anyway, but Maggie’s just grateful she doesn’t have classes tomorrow afternoon, so she’ll be able to be there.

“Eat, Alex. You can’t live on granola bars, okay? Eat. And here.”

She tugs a water bottle out of her pajama pants pocket.

“Drink all of it. The pizza’s salty and the caffeine’s not gonna help.”

The chaotic, stressed look in Alex’s eyes fades for a moment as they look down at Maggie.

“You’re amazing, you know that?”

Maggie grins and reaches up to adjust Alex’s glasses and kiss their nose.

“I have my laundry in the wash, gotta go switch it out. While I do that, can you do me a big favor please? Go take your binder off? You’ve been wearing it a long time today, I don’t want you to get hurt.”

“Why are you this perfect, huh?”

Maggie beams and licks her lips. “Takes one to know one, Danvers. Go. I’ll be right back.”

And she is, and Alex smiles as she curls up in the armchair in the corner of the study room and falls asleep. Alex strips their sweatshirt off and wraps Maggie in it, complete with a gentle kiss to her temple.

It’s nearly sunrise by the time Alex falls asleep, and Maggie stirs in the chair.

“Oh, Al,” she sighs as she takes in the sight of Alex face-planted in their papers, leaning forward on what has to be the most uncomfortable chair in the entire dorm.

“Baby,” she whispers, padding over to Alex and kissing their hair.

“Babe, come to bed, come get some sleep. Your presentation isn’t until nine. I’ll wake you, I promise.”

“All my stuff – “ Alex mutters, more asleep than not but leaning compliantly into Maggie’s arms.

“I’ll come back and clean it up. Come on, handsome, let’s get you to bed.”

Even half asleep, Alex smiles broadly at the term of endearment Maggie knows they’ve come to love, and they let Maggie guide them to their room, all the while muttering about the breakthrough they made around three a.m.

“You’re so brilliant, Alex,” Maggie assures them as she tucks them in, nodding good morning at a bleary-eyed Lucy, shuffling through their shared space in a long ROTC t-shirt and slipper socks.

“They pull another all-nighter?” Lucy asks quietly as Maggie kisses Alex again and tip-toes out of their room.

“Mmhmm. Got coffee?”

Lucy pffts. “Got coffee? Whose room do you think you’re in, Sawyer? It’s coffee paradise in here.”

Maggie laughs and rubs sleep out of her eyes.

“Perfect. Just black please?”

“Das gross, Mags!” a very groggy voice calls from Alex’s room, and Maggie and Lucy collapse in silent, loving giggles.

Bottom!Aomine Fic List

Clearly I have no life. Compiled last night while I was feeling anxious and needed something to busy my brain. Sad to say I have read nearly all of these, most of them several times over. Thank you dear writers for quenching my bottom!Aomine thirst. 

I may have missed a few, but certainly not on purpose. Some of these fics are part of a series, so it’s best checking beforehand. Many of these fics I feel hesitant to label as mere bottom!Aomine fics because they are so much more than that. I apologize in advance if I have hurt anyone’s feelings.

-Deacon thinks that license plates are some sort of code. 

-Danse thinks that the license plates were part of a fad schemed up by the Chinese to infiltrate the United States, and it worked. 

-One of Deacon’s favorite things to do is sing Safety Dance in front of Danse after Blind Betrayal.

-”We can Danse if we want to, we can leave our friends behind. Because if they don’t danse, and if they don’t danse, then they’re no friends of mine.”

-Danse isn’t sure whether he loves it or hates it. 

-There’s a reason why Day Tripper isn’t mixed with any of the other chems. When mixed, it creates an exothermic reaction. Hancock knows this and will spritz a drink with some jet when he sees some asshole try and slip something into a girl (or guy)’s drink at the Third Rail, if he hasn’t already stabbed them for it. 

-Takahashi is actually a very intellectual (and sassy) protectron, but because he has been broken for so long, he has no way of other communication, aside from the usual dialogue. 

-Nick can recognize Takahashi’s emotions by the speed of the gears whirring in Tak’s brain. 

-Nick is a pro at getting off handcuffs, mainly because every person who finds a pair tries to see if it works, and in the process, gets stuck.

You set your mind towards a stable career, and other recreational activities became an obstacle in order for you to achieve your objective. In your world, there were no such time for a social life. Instead of searching for friends and love, you spent your hours studying to ensure your future. Being part wolf was already costly enough for your reputation.

Chlorosulfonation of an imidazole derivative with chlorosulfonic acid.

Why is this a special thing? Chlorosulfonic acid reacts with water explosively forming sulfuric acid and hydrogen chloride. So when I added 200 g of a compound to 500 cm3 of chlorosulfonic acid, a highly exothermic reaction happened and immediately and a highly acidic fog formed in the flask as the reactants contacted each other.

Important note when working with chlorosulfonic acid: NEVER WASH ANYTHING WITH WATER WHAT CONTAINS A RANDOM LIQUID, since if its chlorosulfonic acid, it could blow a highly acidic solution on your labcoat/hands/face. And always pour chlorosulfonic acid and reaction mixtures that contain this chemical on large excess of cracked ice to avoid serious problems.

P.S.: always wear proper PPE.

anonymous asked:

If somebody gets cut across one of their femoral arteries, what are their options? How long do they have?

In order: dying, and somewhere south of two minutes. Death may take a little longer, but loss of consciousness will come sooner.

Where the artery is damage will affect how treatable it is. When you have some distance from the torso (the mid-to lower thigh) you can apply a tourniquet above the wound and possibly keep the victim alive long enough to get them medical attention. In the upper thigh or near the groin, unless you already have EMTs on site, you probably won’t have enough time to effectively clamp it.

That said, the last fifteen years have seen an explosion in technologies designed to counter catastrophic blood loss. This includes things like QuikClot and HemCon. The former dehydrates blood on contact inducing rapid clotting. The latter becomes highly adhesive and is supposed to seal into the wound (though the survival rate was reportedly only around 10%.) Of random interest, early iterations of QuikClot came in powdered form (the current version is saturated into gauze), it used a different mineral base, and had an exothermic reaction on contact with blood, resulting in second degree burns. This saw military use in the early 2000s, and never made it to the civilian market.

There’s also NovoEight, which, if I’m reading this correctly, is recombinant blood (or more accurately, just the clotting factor from human blood). This is sold in powdered form and needs to be reconstituted immediately prior to use (once reconstituted it only lasts about 4 hours).  Technically, this stuff is intended for treating hemophiliacs who were seriously injured or going in for surgery.

An earlier iteration, NovoSeven was used experimentally in the mid 2000s. It can be effective for managing blood loss in cases of severe trauma, but is also risky to use, as it in can result in arterial thrombosis, (clotting in the arteries that obstruct the flow of blood). In case it wasn’t clear, this is a very bad thing, though preferable to bleeding to death. I don’t know if NovoEight still has that risk, though, it would surprise me. Neither is actually approved for use on non-hemophiliacs, but it is an option of last resort. (The primary difference between NovoSeven and NovoEight appears to be how the drug is produced, and the potency (NovoSeven is stronger, and indicated for patients who have no clotting factor, while NovoEight is intended for patients with a congenitally deficient clotting factor.)

If you can get the victim into surgery, then it’s possible they may survive. But, this is still an extremely dangerous injury to suffer, and even medical attention doesn’t mean the victim will survive, only that they might. From what little I know, the actual procedure is just to clamp the artery and suture it back together. The problem is that the femoral artery moves a lot of blood, making it harder to control, and causing the bleed out to occur faster.

So, their options aren’t that appealing.

CLIFFHANGER ENDING! This request comes to you from fuckyeahheedus and basically, I want you guys to choose the ending. I might write both anyway, depending on how much time I have and how I feel, but until then you decide. Good luck and enjoy, my darlings!

Prompt: Will it be cool if I request a kinda part two to there “Conceal, Don’t Feel” where she joins the avengers with Thor who’s obviously going to be her best friend and try’s to hide her relationship with Loki but they catch her talking to him when he’s in the cell made for the hulk? :D

“Conceal, Don’t Feel” (Part 2)

Part 1

Loki stood in his glass prison with his hands behind his back, facing away from the door. He remained that way even when two sets of footsteps could be heard entering the room. Silence. Loki sneered: they were waiting for him to speak first. He turned around slowly with a sarcastic grin on his face.
“So, which of you has come to-”

His face fell.

“You’re… You’re alive.” You said, on the brink of tears. Thor stood next to you with an arm on your shoulder and his brow was low as he eyed Loki’s reaction. Meanwhile, you felt yourself beginning to shake – though whether it was due to anger or shock, you weren’t yet sure.
“…(Y/n)?” Loki said, his voice breaking only slightly as he approached the glass. He pressed a hand against the window as you brushed away a tear. Your mouth was a little way open and a waterfall began to spill from your eyes. You turned and left before he could see you cry.

“Do you see now?” Thor growled. “Do you see what you’ve done?” He made to follow you, leaving Loki to wallow in his own self-pity. What were you even doing here? When he’d fallen from the bifrost, he’d thought he’d be leaving you safe in Asgard. Safe from him – until he could return a better man. A King. Pressing his back against the wall, he slid to the floor and pulled his knees against his chest.

anonymous asked:

Okay, can you write something for Tsukki and Kuroo, where their really cute female lab partner in chemistry passes them a note saying "Uranium Rhenium Copper Tellurium" which in element short hand reads "U Re CuTe" aka You're cute!

This is so cute omfg
Using they/them pronouns to keep it gender neutral, as always

Tsukishima snorted once he read the note, a small, rare smile spreading across his face. It didn’t take him long to realise their feelings behind it, as they were sporting a bright blush and carefully looking at him from the corner of their eye. He decided to humour them on it, flipping the paper over and quickly scribbling down a note of his own. When the teacher wasn’t looking, he slid it back over to them, waiting to hear their muffled laugh at the words.
You must be a compound of barium and beryllium, because you’re a total BaBe.

Kuroo couldn’t help but giggle at it, prompting looks from the people sitting closest to him. He spent a while thinking of his own line, grinning broadly once he thought of one. Scribbling ’You’re like an exothermic reaction, you spread your hotness everywhere!’ under their pun, he gave it back to them, holding in a laugh at their reaction. The next ten minutes were just a back and forth passing of paper, each with a different chemistry pun on it, until they got caught by the teacher and separated. Kuroo still risked one last note, giving it to his new lab partner to be passed back around the room.
Are you made of copper? Cause I Cu in a relationship with me.

EXO Wolf! AU - Pursuit Ch. 2

Ch 1 ~ Ch 2 ~

Pairing - Reader x Baekhyun/Chanyeol

Summary - You’ve been to plenty of schools and you didn’t expect this one to be any different. You presumed you’d still continue with your quiet hardworking life, unaware of any social connections. That is, until EXO comes along and completely ruins your reputation by introducing you to their exotic (see what I did there) world.

Hearing a crowd of screams, you turn to see nine boys strolling directly down the middle of the hall, surrounded by a crowd of what seemed like lunatic fangirls. Squinting, you find Baekhyun part of the seemingly popular group, accepting gifts from the girls. Thinking back, you remember him saying something about his crew, something with ES, or was it-

“EXO!” a girl screams out, followed by more chants of their name. Seriously, were they just popular, or secretly an idol group? You turn around and continue making your way to chemistry.

“Ugh, move!” a girl from the side pushes you, making you stumble. You look over to glare at the rude girl, but before you could say anything, you’re bombarded with a large crowd of females, dragging you away like birds fighting over food.

“What the-” you try to voice out in the cramped space.

“Who gave you the right to walk in the same aisle way as EXO!”

“I cannot believe you just disrespected our boys like that!”

“Who do you think you are?”

Snide remarks were thrown at you in every direction, all claiming you somehow violated your right in being an EXO wolf or whatever the hell that was. You tried to push back, but it was a hopeless battle against so many of them. Soon enough however, the attacks ceased, as the girls crowded around another point of interest. Of course, it was none other than EXO themselves.

“Are you okay?” one of them asks, making you scoff.

“Yeah I’m alright. No thanks to you.” they were the reason why there was so much fuss going on here in the first place. Couldn’t a girl just manage her way through the halls normally without the trouble known as EXO?

“I’m sorry that our wolves acted this way towards you, I’m Chanyeol by the way.” a taller boy with short black hair extends his arm, expecting you to shake it. Seeing as all these ‘wolves’ were still crowded around, you shook his hand, not wanting another attack. You could see another boy lecturing their fans about their behavior, saying that you were new, and didn’t know the “rules”.

“What class do you have next?” Chanyeol asks, redirecting your attention back towards him.

“Chemistry.” you replied.

“Really? Me too!” you give a weak smile, cloaking your disappointment of having another EXO member in one of your classes. You walk away quickly, trying to avoid any more drama that could be created near that crowd.

“Hey, let’s walk to class together!” Chanyeol calls after you, making you bite your lip in annoyance.

“I have to go to the bathroom first!” you call back, quickly thinking of an excuse. It technically wasn’t untrue, as you needed to fix your appearance from those crazy wolves. As expected, they created countless tangles in your hair, and dismantled your outfit.You didn’t care, but you knew someone else would, *ahem mom ahem*.

Walking into the chemistry classroom, you were disgusted to see a group of girls crowd around the boy you met earlier, Chanyeol. Girls seemed to throw themselves at EXO members whenever possible, making you confused to why they were so idolized. The only reason you could think of to why people would worship this alpha group so greatly was because of their looks.

“Okay everyone, may all of you girls crowding around Chanyeol please return to your assigned seats so we can start today’s lesson.” At the teacher’s words, you could hear multiple sighs and heels clacking on the tiled floor.

“Today we are going to review endo- and exothermic chemical reactions. Laid before you is a lab in which you will conduct several experiments on. With the ingredients provided, you will create one endothermic or exothermic reaction. The materials will determine which kind it will be. And before you all fight over Chanyeol as a partner, I’ve already assigned everyone. Your and your partner’s names should be labeled at the corner of every lab.” The whole school system even seemed to know about EXO and their reputation judging by this teacher’s inquisitive actions.

Finding your seat, you plopped your stuff down, and started to inspect the materials laid in front of you. Citric Acid. Baking Soda. You sighed at the simplicity of this experiment. All you needed to do was combine these, and you’d make those weird homemade “volcanoes”. Either this high school was terribly uneducated, or the teacher took this review a little too far back into elementary school.

Your partner still hadn’t arrived next to you, striking you a little odd. Was it really that hard to find a name? Looking over, you see that regardless of the teacher’s words, a small crowd of girls still surrounded Chanyeol, relentlessly flirting with him. Your partner’s name seemed feminine, so you made a relatively secure bet that she was one of the girls with their arms draped on the EXO member’s shoulders. You sighed realizing you’d have to do this stupid lab on your own.

You reluctantly put on safety goggles as the instructions demanded, although it was highly doubtful that this lab would be anywhere near dangerous unless you were an idiot. The safety goggles that were given were unusually loose, and you immensely struggled with tightening them. Before you could take them off to exchange for a smaller one, you felt a pair of hands on your shoulders stabilizing you before moving onto the goggles to adjust their strings. Turning around, you see no one other than the infamous Chanyeol himself. You roll your eyes at his smirk that made chicks drop.

“I appreciate your help, but I can handle things myself.” you reply before returning to your designated location. Chanyeol however, followed you the whole way back.

“Um, why are you following me?”

“I’m your partner.” Chanyeol shrugs coolly and proceeds to put on his own goggles.

“Last time I checked, your name wasn’t Jessica.” You read off the name plates again, making sure the label was correct.

“Well, I got reassigned. Apparently my partner was too distracted by me.” You mutter a soft ‘of course’ under your breath before continuing the lab.

“You know what kind of reaction this is right?” you sigh, hoping he wasn’t as ditzy as his followers seemed to be.

“Well, we’re in chemistry, so I’d expect it to be a chemical one.” you raise an eyebrow, unsure whether he was kidding or not.

“I’m joking, you didn’t think I was serious right? It’s obviously an endothermic reaction.” you let out a breath in relief, thankful you weren’t stuck with a stupid person, although you were expecting that.  

The worksheet given to you only told that you had to develop the experiment, and write down the steps and observations you noticed. This had to be the easiest thing in the history of chemistry, yet this was planned to take up the whole period.

“Okay, so let’s just get this done and we should have plenty of time left to do whatever we want.” you told Chanyeol, and begin to set up the experiment. The baking soda and the thermometer was put in a flask, and all that was left was to pour in the citric acid solution.

“Is it just me, or does this citric acid smell super weird?” you look over to see Chanyeol taking the small flask, sniffing it. You try and take the bag from him to finish the experiment, but instead he grasps your shoulder yet again, and pulls you in close to smell the flask.

“It smells a bit like lemon, and maybe a slight hint of sulfer…” Chanyeol rambles on, making you confused to where he was smelling all of this. Citric Acid is a low-odor substance, and yet he’s listing all these ingredients that he could supposedly smell. Convinced he was bullshitting you, you snatch the flask from him, and pry his fingers off your shoulder.

“Citric Acid doesn’t smell like anything dumbo.” you exasperate before pouring it in with the baking soda.

As you were writing down the results, you feel Chanyeol’s finger play with your hair, twirling it around his finger, and brushing out the tangles, and you reached over to bat his arm away. Damn, was he always this touchy? Unfortunately you missed hitting his arm, and instead brushed the flask right off the desk, making it shatter on impact with the ground. You looked around, seeing that the teacher did not hear or notice the glass breaking. You flashed an apologetic look at Chanyeol before crouching down to pick up the pieces.

“Here, I’ll do it. You might cut your fingers.” Chanyeol joins you in collecting the glass.

“It’s my fault, I’ll do it.” you continue to gather the shards, ignoring his warning. As expected, you cut your hands drawing small amounts of blood.

“See! I told you that you’d get hurt!” Chanyeol pesters, seeing the drops of blood.

“Well you got hurt too!” you contradict, seeing he also had cuts on his fingers. You see Chanyeol sigh before going to get the first-aid kit from the front of the classroom. Meanwhile, you try to blow on the cuts, trying to stop the stinging.

Chanyeol takes your hands in his, and carefully applies the bandages on each of the cuts. You could’ve sworn all the girls had envy plastered all over their faces, seeing how close Chanyeol was to you. They had nothing to be jealous of though, as you had no interest in him.

“Aren’t you going to get bandages?” Chanyeol had applied the last bandage onto you, and he seemed to have no means to bandage his own cuts.

“Nah, I’d seem like a wuss.” you shake your head while smiling at Chanyeol’s pride, knowing exactly he was more sentimental than ‘manly’. The bell rang, signaling the start of lunch.

“Y/n, I know you’re new here and might’ve not met a lot of people, so you should come hang out with us at lunch.” You concluded that Chanyeol meant EXO from the terms of ‘us’, and judging from the past experiences with them, you’d get plenty of death threats from their wolves, aka die-hard fangirls.

“Thanks, but-”

“What was that I hear? Was it a happy yes? Okay then, if you say so.” Chanyeol wraps his arms around your waist, leaving you with only two questions. One, why was he so goddamn touchy? And two, what had you just gotten into?

Taking a closer look at his hands, you see there was no longer any evidence of the cuts he’d gotten a few minutes earlier. You were sure it was just a trick of lighting, but his skin looked clearer than before he got the cuts. There was no way he could’ve healed that quickly right? Before you could confuse yourself further, Chanyeol begins talking, taking your attention off of his hands.

As you can see, this chapter was more Chanyeol based (he’s my bias too), and there is more chemistry (haha lol pls stop my terrible puns) between EXO and y/n. Thank you for reading everyone and love you! - Kiwi

Mercury(II) Thiocyanate:  The Pharaoh’s Serpent

Mercury(II) thiocyanate (Hg(SCN)2) is an inorganic chemical compound, the
coordination complex of Hg^2+ and the thiocyanate anion. It is a white powder. It will produce a large, winding “snake” when ignited, an effect known as the Pharaoh’s Serpent.  The first synthesis of mercury thiocyanate was probably completed in 1821 by Jöns Jacob Berzelius:

  • HgO + 2 HSCN → Hg(SCN)2 + H2

Evidence for the first pure sample was presented in 1866 prepared by a chemist named Otto Hermes. It is prepared by treating solutions containing mercury(II) and thiocyanate ions. The low solubility product of mercury thiocyanate causes it to precipitate from solution. Most syntheses are achieved by precipitation:

  • Hg(NO3)2 + 2 KSCN → Hg(SCN)2 + 2KNO3 

Mercury thiocyanate was formerly used in pyrotechnics causing an effect known as the Pharaoh’s serpent or Pharaoh’s snake. When the compound is in the presence of a strong enough heat source, a rapid exothermic reaction is started which produces a large mass of coiling serpent-like solid. An inconspicuous flame which is often blue but can also occur in yellow/orange accompanies the combustion.
