Smoking Penny - Chemistry After Hours 3

[freshdude56]

nice bong

[DrHiptotheHap]

Penny Smoke. Don't breathe this.

[lexichronicle2]

some pigeon on the roof's probably coughing his ass off

[thesodathief]

put balloons on top and offer 3 to enemy then we near him pop em all!

[Zamriasra]

replacement reaction ?

[WhiteTrashSingers]

Nice placement of the music

[THISNAMEOWNS]

aww...i thought you were going to smoke that

[NexonPlayerNA]

Looks *cough* like *cough*cough* what I was *HACK*WHEEZE* smo- *HACK* king a sec*OUGH*ond ago. WAI- *HACK*COUGH*WHEEZE*BLARGH* ಠ_ಠ

[Killinemdead1]

i have a structured settlement and i need cash now

[skatemental702]

that is a federal offense sir.

[Seto0019]

Nitric acid (highly conc.) with copper=MUCH NO2.

[NoobsAreUsh]

SCIENCE

[Nightlylioness]

Why exactly was there green at the bottom?

[Agentoxedo07]

Holy-Terrorist:>*=* crock!

[Altoclarinets]

@ericgiffly Rough guide: In chemistry, color usually is a good indicator of toxicity. The stronger the color, the more toxic. Are "NOx-ious" gases poisonous? I'm going with a Yes.

[Altoclarinets]

If there's any one thing chemists love, it's defacing currency ... between this and the HCl lab in which you take an unfortunate post- 1982 penny, file a section down to the zinc core, leave it in HCl overnight and return to find that it is merely a shell of its former self... :)

And that icky brown stuff spewing off the top? That's what gives smog its... ahem... distinctive color and odor.

[zombieboy268]

auto bong

[TheLotharx]

Fact: It costs more than $0.01 to make one penny.

[PikminExpert]

2.5% copper.

[holdenm1244]

hmmmm killer gas gives me a idea NAH JK

[mattmax11]

hope this was done under a fume hood

[wakedonzi]

I hope your in the hood.

[magdag88]

lol nitrose gase^^

[ihatestupidvideos]

the penny's not even worth a cent anymore

[omegahunter9]

@ihatestupidvideos and did you think that those dollar bills of cloth and paper were worth more than a dollar? Our currency is literally worthless other than the value we assign to it. Pennies are relatively more valuable.

[ghdtw]

This is basicly the reaction of nitric acid with copper producing the gas called Nitrogen Dioxide.

[vmelkon]

@ghdtw 8 HNO3 + 3 Cu → 3 Cu(NO3)2 + 4 H2O + 2 NO

2NO + O2 → NO2

[yellowmetalcyborg]

@vmelkon Owned LOL!

[MegaGamer50]

amazing on how people use teargass and grenades instead of this acid cloud. wtfman? srsly military is kinda stupid, people even invented lasers that burn thru ur face over small periods of time jeeeez i mean military is stupid if they dont use that stuff dang

[Monkeynuts502]

@MegaGamer50 Have you seen the microwave truck the military built?

[MegaGamer50]

@Monkeynuts502 yes, i've played command and conquer

[Monkeynuts502]

@MegaGamer50 I mean in real life...

/watch?v=J1w4g2vr7B4&feature=f­vw

[MegaGamer50]

@Monkeynuts502 yes, ive played the sims

[unstoppable008]

My friend and I had our own "After Hours Chemistry" during an AP class we took last year as juniors in High School. Except, instead of just dissolving copper with Nitric Acid, we made our own concentrated acid. We did it with some Sodium Nitrate, Hydrochloric Acid, and Copper. Put it all in a vacuum flask, and funneled the gas through some water. It worked really well, and we had a great time just doing our own thing.

[ThePizzahero1]

NOx gases are cool

[MDF12]

defaceing money or destroying money is against the law!

[fatalCondor]

penny smoke dont breath this

[iExD]

@fatalCondor lmao. that reminds me of the guy from will it blend

[Serostern]

@fatalCondor More like NO2, don't breathe this.

[digitalbroadcaster]

I bet people outside were wondering why you had so many dead birds lying on your roof next to that smoking chimney? :o)

[spotlightman1234]

i love NO2 :3 how can i get some? i have HCl and nitrate salts?

[DOCTOROCTAGONAPUSS]

where can i get some of that stuff?

*prepares to pour on brothers head*

[dumle29]

is this an exothermic reaction?

[DOCTOROCTAGONAPUSS]

@dumle29 wtf man speak english lol

[Channypogosticks]

holy cow, when i saw that i was like MUSTARD GAS.... damn the germans..... must be a bad death for the soldiers...

[escdcrazy]

Are the pennies like clear now!!

[VivaLaUndead]

@escdcrazy ....... le sigh ...

[dinkydoghnut]

what did you add in?

[itawwwa]

When I do this, can I try to catch the escaping NO2 and bubble it through water to dissolve and create HNO3 again? To save some acid...

[Kalash239]

@itawwwa Yes, that or hydrogen peroxide, stronger the better

[Biotheck]

And that's how the credit crunch started! XD

[Longboarderization]

Don't know if anyone is confused by this, but the brown gas is NO2, not some kind of vaporized Copper despite the color XD Just so we're clear

[valstachowski]

cool!

[blueduderanch]

the equation for this reaction is as follows.

3 Cu(s) + 8 HNO3(aq) → 3 Cu(NO3)2(aq)+ 2 NO(g)+ 4H2O

the coloured gas is NO. not N2O(nitrous) and not NO2(nitrogen dioxide)

The gas produced is Nitrogen monoxide.

[blueduderanch]

2 moles of the nitrogen monoxide then reacts with a mole of oxygen to produce the nitrogen dioxide

[plaidchuck]

so is this single displacement? also is it NO or NO2 because the description says it's NO2 (nitrogen dioxide)

[blueduderanch]

NO is produced, then it reacts with oxygen in air to form NO2 which is coloured.

[plaidchuck]

so what type of reaction is it?

[blueduderanch]

@plaidchuck it is displacement and oxidation. two separate reactions taking place one after another but look like one reaction.

[evan1005]

@blueduderanch No, the brownish gas is nitrogen dioxide (NO2). Nitric oxide (NO) is colorless.

[blueduderanch]

@evan1005 but that is because the NO is then being converted to NO2 in another reaction with air, not in the penny reaction.

[erjohnson227]

N02 is very very toxic.

[ilikepiewifcream]

its narutos 9 tailed beast chakrak!! lol

[teehee0]

noooooooo you wasted the mana pot!!!!!

[chemtraderq]

the brown colour is caused by NO2. If the temperature is above 150°C NO2 starts to break down to NO. The equilibrium is fully at NO if the temperature is above 650°C

[stigomaster]

What is causing the brown colour of the gas? According to Wikipedia nitrous oxide is colourless.

[LedKenji666]

@stigomaster its nitrous dioxide

[codydeyarmin]

its definitely copper nitrate. nitrous is clear

[LedKenji666]

@codydeyarmin nitrous is just an element N so do you mean N2 is clear or NO is clear or NO2 is clear nitrate is N with O i think so do you mean CoNO?

[blueduderanch]

you are so far wrong. N2 is clear and is nitrogen NOT nitrous. nitrous is N2O and is also clear. NO2 is nitrogen dioxide and is the brown colour. it is by no means CoNO!

[LedKenji666]

@blueduderanch hey im french i dont use the same terms so i might be wrong for the terms

[LedKenji666]

@blueduderanch it was all a question so why you say im wrong idiot

[blueduderanch]

no its not

[MusicWavesMan]

yes it is.

[LevaniaDaemon]

NO is colourless

[HazMatLabz]

cool, black pennies. wonder if there is a chemical in which you could electroplate things black?

[jusTlikehmf2]

would be sweet

[InfernoPicsAndVids]

Add a match inside then throw at girls houses :D

[142suckerpunk]

wow :D

[ImSuchACoolStrongMan]

No.

[mylittlestriper]

it is against federal law to destroy U.S. currency.... but freaking awsome

[kingvater]

Not if the currency is Made before 1979. Just saying:p

[UncLester]

@mylittlestriper It is only illegal to deface/alter currency with fraudulent intent. It is your right to do what you want with your currency as long as you do not pass it off onto someone else. Title 18 United States Code, Section 331

[Nobakani]

@mylittlestriper Nothing gets lost, nothing comes up, everything changes...

[forallpurposesonly]

@mylittlestriper Unless when you get it back to circulation

[ConservativeAtheist9]

@mylittlestriper It's only illeagal if it's with the intent of changing the value, so only freaking awsome.

[paulbalancio]

looks like fruit punch with alotta sugar XD

[jeanlucvar]

Excellent, congratulations, I tried also with copper, brass etc. ... This gives my pottery glaze blue, beautiful.

But also with silver and gold. See my video;

and if you have any other ideas of metal, tell me your suggestions.Merci

[mingmingnak]

nitric acid will not react with gold what are you talking about?

[jeanlucvar]

Hello (politeness compels)

you also , you tell , anything, read again your formation.

Nitric acid reacted well on gold, very well.

I make color a purple of Cassius.

All professional jewelers and goldsmiths, using well Nitric acid is very known.

My wife is creator jeweler

Read also , what is , gold chloride and look at my video on the topic and many other experience video on Youtube with Gold and Acid Nitric.

Sincerely

And Merry Christmas and Happy New Year everybody

[entoris476]

nitric acid doesnt react with gold -.-

[jeanlucvar]

That's right, Oh !! it's really not a luck.

But, know you the story of Cassius Purple and the aqua regia and Chloride Gold ?????

[entoris476]

yah but nitric acid is the oxidiser in the aqua regia not the actual reactant

and did you mean 'Gold Chloride'?...

[jeanlucvar]

Yes, you're right, exactly, but I use very well , nitric acid for aqua régia .

For the Gold Chloride , I use , for my special Potery and color Cassius Purple.

See my last video on Youtube

Best wishes for new year

[davidng5000]

how about mercury

[HazMatLabz]

@davidng5000 yes, mercury does react

[LRchron422]

thats where my bong went..:(

[MoultonProductions]

@LRchron422 Lol,you wish.

[badlady468]

this is cool

[search4unknown]

What did you use for the base to neutralize the reaction?

[search4unknown]

haha the nitric acid is burning threw the penny's. Sweeeet.

[jackTHEretardSLAYER1]

where can i find nitric acid

[TheLeafeonGirl]

That looks kinda scary o.o

[Ksquaredgaming]

EPIC MUSIC

[darkeyce02]

cool, i think my old class did this. or something similar

[shortyecu12]

Those 2 colors at the end are Tiighhtt

[linky886]

i can spell fumehood ;)

[douro20]

The reaction produces copper (II) nitrate and nitrogen oxide which reacts with oxygen in the air to form nitrogen dioxide...the products are actually more dangerous than the initial reactant.

[pmgba525]

and dinitrogen tetraoxide, the brown gas~

[Blackmystix]

It started spewing shit fog

[oldschoolmagic]

does this take away the brown color the penny's have?

[GWNProductions]

Pennies made after 1982 have a copper coating (brown) over a zinc core. If you let this reaction go long enough, you may be left with just the zinc core. You can see that to some extent with the black pennies at the end of the video.

[spotlightman1234]

@GWNProductions thw zinc would also be eaten up by the nirtic acid

[shall51994]

any visible gas is poison so yes u will die

[DOCTOROCTAGONAPUSS]

@shall51994 not true...

what about...oh damn your right i geuss frozen air is carbon dioxyde...lol whoops nm man

[drocker4]

that kills!

[niblet4123]

Nitrogen dioxide is toxic by inhalation, but this could be avoided as the material is acrid and easily detected by our sense of smell. One potential source of exposure is fuming nitric acid, which is often contaminated with NO2. "Symptoms of poisoning (lung edema) tend to appear several hours after one has inhaled a low but potentially fatal dose. Also, low concentrations (4 ppm) will anesthetize the nose, thus creating a potential for overexposure."

From Wikipedia

[DOCTOROCTAGONAPUSS]

@niblet4123 can you say that again in english pls 0_o

[xXCriptlordwcXx]

*makes 1 and puts a cork*

NOW FOR MY MAGIC SPEL!! *smash it on the floor and a cloud of brown smoke*

*on the floor twitching*

[Monkeynuts502]

@xXCriptlordwcXx this comment made my day.

[slimjim561]

yes, you die a painful death.

[jaydubya777]

what would happen if you did the same thing with silver or gold coins?

[weylin6]

breath it in

[Rachey827]

lol

[theshadow33333]

hhhhh try to smake it ur gonna get high till heaven man./

[F3tusRape]

That's because you have ADD.

[shadowshark499]

looks like a bong

[elliotmotoX]

Nitrogen Dioxide or Nitric Dioxide?

[medic007]

the latter...

[DownloadsForFree]

Nitrogendioxide

(Not sure but it's first nitrogenmonoxide, but it reacts with the oxygen in the air into nitrogendioxide

[funkmasterfares]

What concentration of Nitric Acid did you use?

[Jimmymajesty007]

dumping cold water into the hot flask isn't a good idea...

[roxas4631]

lol

[ScreamingElectron]

Great thanks for contributing to 50% of the worlds SMOG :)

Try not to breathe that shit in btw

[CrazedPsychic]

you lose pennys all the time i think its legal to do that

[MMMAAATTTLLL]

is it legal for you to do that to pennies???

[DylanDominguez6000]

looks like a bong

[ilikepie41222]

you would know

POT HEAD!

[BlueFocks]

You wouldn't know

NOT A POT HEAD!

[ty549]

i said to myself before looking at the comments.. doesn't this look like a bonggg

[Anthonyk312]

whats with people thinking round bottomed flasks always are related to drugs. i mean almost every lab we have someone says it looks like that

[TheDrkKnght1988]

I used to do this when we're preparing the CuCl during my general chemistry lab class. It's pretty interesting.

Once concentrated HNO3 added to copper metal, then copper turns into Cu+2 ions and produces a nasty toxic brown NO2 gas! Whoa!

[elliotmotocross]

uh oh nitrogen dioxide :X

[potassiumperchlorate]

whaha nitric acid and copper:P

[siriusblack9999]

someone in my class did that, there's still a light-brownish stain in the acid closet XD

[WesByNorthWest]

One of my high school teachers did this experiment for us...only she used too many pennies and too much acid so the entire classroom started filling and we had to evacuate while it cleared...

I still have memories of her frantically clapping wet paper towels over the top of the beaker to try and stop the gas

[GWNProductions]

Yeah, it's best to do something like this in a hood with adequate ventilation. Even then, you can get some gas leaking into the room.

[WesByNorthWest]

This was also the same teacher who had the sodium she put in water explode like firecracker and set fire to nearby paper towels.

Not really her fault, but it added to her legacy.

[HerrCaZini]

the red-ish smoke almost looks like vapor from bromide ? or is it someting else?

[HerrCaZini]

bromine i mean ...

[GWNProductions]

There wasn't any bromine involved.  It was just copper and nitric acid.

[slither888]

It's NO2 and probably a trace amounts of other NOx gases.

[theelementor]

@HerrCaZini that was nitrogen dioxide NO2 from the reaction between copper and nitric acid.

[xXKentoXx]

Isn't this illegal(melting money)

[scottymac2008]

not if its your own. lol

[xGingerxSnapsx]

Awsome! :):)

[Omnis2]

yay NO2.

[gnrfan32]

lol, shotgun!

[comarocing]

NEXT GEN SMOKE GRENADE!!!

[slither888]

yeah, if you'd like to kill your opponent!

[Thewhitewookiee]

haha we did this reaction accidentally the other day while fucking around with some 16M nitric acid and a quarter.. luckily, i identified the N2O and used a fume hood, but i dumped the nickle nitrate down the drain (so much for the fishes)

[boygenius13]

shouldn't you add the nitric acid to water, not the other way? purely for safety sake?

[bluedragon62]

Well, yes...but that isn't really relavent here...? We didn't mix the acid with water in any way...so...

[boygenius13]

what do you mean we? are you in this video?

at the end he dilutes it which turns it into a pastel blue. which is what happens when it is mixed with water.

[bluedragon62]

Yes, I am in this video. I was actually the one that suggested we do this particular experiment for this after hours video, and the hand you see pouring the acid in the beginning belongs to me. ;)

And good call on the dilution. I had forgotten we did dilute it at the end (it's been a few months since we did it or since I had watched our video). Yes, technically we should have added that acid to water; what we did could have caused some nasty bubbling and acid splatter.

[soccerbumm1010]

I bet those pennies were clean afterwards! lol

[spclagentsteve]

haha not really...those pennies were gone afterwards...did this in chem today, it was really cool

[bubblgum234]

k do the reaction in a reagular bottle thing and put a plug on top n see if it blows up...

[GWNProductions]

Watch our other video with pennies and nitric acid where we have balloons on top. I think that's the type of thing you were aiming for. It's called "Chemistry After Hours 5."

[BAZOOKA30215]

unfortunatly no, he wants you to recreate a "dry-ice bomb" with it. that involves you putting dry ice in regular 2 liter bottle with water (about 2/3 full) and close the lod. after a while the gas build up of the water and dry ice will burst the bottle in a loud bang. its pretty cool, if you didnt know. but im sure that wont work because that the acid will eat the bottle open plus if it did work the gas is extramly harmfull. dont count on it bubblgum234.

[GWNProductions]

That sounds similar to putting drano and aluminum foil in a pop bottle. It makes a bang, but it doesn't require dry ice. However, I'd avoid doing "experiments" that can be construed as bombs.

[BAZOOKA30215]

I like doing either, there fun. But i dont do anything in an unsafe way.

[twyla3]

I wonder why some of the pennies were affected and some were not... could it be you used US one compared to Canada ones?

[bluedragon62]

The reason some of the pennies appeared affected while others didn't was simply that we did not allow the reaction to go to completetion (you can see that we added water to it at the end to slow down and eventually stop the reaction) - so not all the pennies were fully reacted upon by the acid.

[HAMMERON825]

that blue liquid is cpper oxide ?
