magnesium in dry ice

[Zeldagigafan90210]

It sounds like he's saying "manganese," which is a completely different metal from Magnesium, which is either an alkaline, or alkali earth metal (group 1 or 2), manganese, on the other hand, is one of the several transition metals.

[nobazter]

@rhblakeman yea ur rii maganese is used to alloy to add to corrosion resistance and magnesium is used for its light weight and probably reasons im not sure of

[ISkateBackwardsHelp]

Wait, so your not supposed to stare and magnesium lit? My teacher lit some on fire and nobbody could take thier eyes off it!

[oomblikkies]

He said manganese twice 0.13 and 0.18. and later he referred to magnesium.

[nobazter]

idk who to believe the professor or this video cuz maganese and magnesium are to different types of metals,,,, im guessing the video cuz magnesium fire is hard to extinguish u usually have to use dry powder

[rhblakeman]

@nobazter The extinguisher for burning metals is a Class D extinguisher and is (as you stated) dry powder made of sodium chloride, copper powder or graphite powder - easily confused with dry chemical types. Use of a dry chemical extinguisher instead of a dry powder Class D can make things worse.

[nobazter]

u do know hez using maganese instead of magnesium

[rhblakeman]

@nobazter Manganese (Mn) is a non-reactive metal, magnesium (Mg) is highly reactive. I don't think manganese burns but magnesium burns well (used in flashbulbs in years passed). Manganese is toxic like chromium (element in the table before manganese) and magnesium is pretty safe. Manganese is used as a steel additive with other alloys to make steel rust resistant (ie stainless steel) and magnesium would likely burn off in molten steel. Pretty sure he was using magnesium.

[TheEpson8]

you could set fire to the wooden table

/watch?v=uoW1srvD4CE

here magnesium burns... ;)

[MakailaJ101]

what class is it called where you do elemental expirements

[unknownethnicity]

This is not the element magnesium. It is manganese. Just saying.

[NeverMind9132]

@unknownethnicity It's magnesium, the professor accidentally called it manganese.

[Malfruk]

@NeverMind9132 You sir... no offense... derp. Magnanese, and Magnesium, are two different elements... source = periodic table of elements...

[NeverMind9132]

@Malfruk Work on your reading comprehension and get back to me. I know manganese is an element. The professor said "manganese," but the material he is using is actually magnesium.

[Malfruk]

@NeverMind9132 Ooops... I apologize for my now EPIC derp!

[hifeyracer]

is this the harry potter school??

[R5H4D0W]

I can't figure out how he managed to light it, magnesium has superb thermal conductivity. if the other end of what he was trying to light touches the ice... well, lets just say he will need alot of propane. :)

[UglyAmerican00]

@R5H4D0W if he was lighting dust, the other side would be more magnesium...Please keep dumb thoughts to yourself.

[R5H4D0W]

@UglyAmerican00 I'm simply trying to say igniting magnesium in powder form, after prolonged exposure to ice, is not readily capable of ignition. This statement is written after first hand experience in replicating the experiment. Call it a dumb thought after you try it yourself.

[DefNerdz]

@UglyAmerican00 Its not a dumb thought, he is wondering how he managed to light it. Please keep your rude comments to your self.

[KevOPyro]

Tahts a New Iphone App :))

[oxsuperjackxo]

MAN-GAN-ESE != magnesium

[whiteydumb]

Sorry but I know a bit about metallurgy and those 2 elements are not the same but are different, different numbers on the periodic table

[evilplatt]

@whiteydumb two entirely different elements, you are correct.



[isopycnic]

Sorry about the carpet.

[MrThatwentwell]

keeeeeeeeelllll meeeeeeeeee

[nateDawg12346]

1:17 bless you!

[UglyAmerican00]

@nateDawg12346 Thank you

[svensverigeqx]

Ofc the mix contains an oxidizer wtf

[HappyMunky1087]

i thought it was suppose to be magnesium. why is he sayin manganese?

[223Lars]

Cool lightsource for Home ;)

[Rogie3210]

most fun that i had in science was putting a test tube in my ass

[boomstick900]

@Rogie3210 Next time you do that, have a rubber stopper ready with a small hole cut in it that a match will fit in. Then fart in the test tube, quickly stick the stopper on, light it, and shove it on up there. Flame first of course. If i can get 1000000 people to test this theory I have, then I will have done the world a great service.

[Rogie3210]

@boomstick900 thanks a lot man i'll let you know how it goes!

[jfpinell]

The video wasn't long enough, and I was no good in chem. class! ....Why does the flame not go out? CO2 chokes out O2, CO2 takes the heat away....I'm lost. And did he say something about the CO2 gas BURNING?? Uhhhhh.....What the heck??

[xThizu]

@jfpinell Oxidator

[jfpinell]

@xThizu I'm lost. See this is why I had everyone scared in chem. class back in H.S.! :)

[xThizu]

@jfpinell lol

[darthmul1]

@jfpinell

magnesium does not need o2 to burn which is why it also burns underwater



[jfpinell]

@darthmul1 How?? What about the fire triangle (heat fuel oxygen)? Strange! Or does it "create" its own oxygen because of its heat intensity?

[Salda007]

@jfpinell @darthmul1 Magnesium does need oxygen to burn, but it burns so hot that it causes the CO2 or H2O to break down. 2Ma + CO2 -> 2MaO + C, and Ma + H2O -> MaO + H2. Yup, magnesium burns in water and produces hydrogen gas. Fun stuff!

[Caramellofellow]

On a wooden table. >.<

[jesusisahugefaggot]

Not magnesium please change the title

[mynameismatt2010]

@jesusisahugefaggot Manganese doesn't burn like that, magnesium does, the professor was saying the wrong thing, not the title.

[jesusisahugefaggot]

The professor said manganese

[Rep0007]

My what a great classroom experiment. Oh dear, the horrible magnesium sparks are flying out onto the students. Look, the magnesium is stripping oxygen from their flesh too. How instructive.

[budsmokersonly2008]

it burns better in co2 thhats why the dry ice is there it makes the fire bigger.

[LizzyAston]

im sure putting Co2 on a metal fire would help to put it out. as seen the reaction took place much more slowly with the block on (this may be due to the lower temperature but still)

when releasing Co2 from an extinguisher it is really really cold, so it will help to put out a metal fire

[resqjason2]

@LizzyAston CO2 in an extinguisher is a liquid which turns to a gas due to the pressure change when released. dry ice is MUCH COLDER that gaseous CO2. dry ice has a temperature of -109 F and the gas from an extinguisher is around -89 F. dry ice is colder and CO2 is really 2 oxygen atoms and one carbon atom. when metals burn they can break the atomic bond and use the oxygen contained

[LizzyAston]

@resqjason2 ah ok thank you. have a nice day

[Nightmonkey17]

You can make graphene using this method!

[jimpeel]

Magnesium fires can be put out with Portland cement.

[BankaiIchigo12345]

With the guy's accent I can't hear what he's saying in explaining it.

Maybe someone posting here can explain to me just why the CO2 is not putting out the Mg fire.

[nasanasa3]

@BankaiIchigo12345 Magnesium burns so very vigorously, the reaction strips the oxygen from the CO2 and leaves the inside of the block of dry ice black with the leftover carbon

[BankaiIchigo12345]

So I can't put out a magnesium fire with a CO2 fire extinguisher then. So what CAN I put it out with then?

[nasanasa3]

@BankaiIchigo12345 MET-L-X dry sand fire extinguisher, or if it's small enough, a fairly large quantity of dry sand.

[cooldarendude180]

I was always tought never to look directly into burning magnesium becuase you could go blind

[djteac]

coooool. I want one of those.

[lilmonkeymagic666]

.manganese , magnesium... who cares...whatever it was it produced something cool to watch =.=

[ArtanisOwns]

lol manganese

[ScagAteHer]

that would make a really cool lamp

[JohnsonGetDown]

@ScagAteHer

haha literally :D

[Live4Ringette]

@ScagAteHer well, magnesium is a very bright substance once lit, although it looks good, in real life if you stare at the magnesium (on fire) it will start to burn your retina and that is why you never look directly at it once lit & if you had it as a lamp, constant exposure to your eyes would cause blindness.

[dukilaki]

i want that burner

[killenpokemon]

Excuse Me The title says magnesium, then why did Mister Doctor Professor say Maganese

[TheLaughingMan0603]

@LilWayneMetalGod I don't know what the fuck are you doing here but YOU ARE DOING IT WRONG!

[Re1Mu2R3]

@TheLaughingMan0603 Yo yO Y0000000OOOOHHH!!!! I waZen't tRowLlin' wHun I pousThud daT shIt RyT thUR, nIGgA buT noW ya menShun it, you GON gIT ya Ass TROLLED!!!

[TheLaughingMan0603]

@Re1Mu2R3 i know hot it works dude, i'm not pissed off :D

you are writing like that because you are doing desperate atempts to troll everithing that you see in the screen, metal music videos etc..

Have a nice day ( :

[041992abril]

galing naman ! :DD

[DigiTan000]

Does this improve flavor?

[OrionWong1]

why is the fire blue?

[Timespartan111]

I always wanted a tv in my bathroom...

[CbN199409]

welcome to chemistry class. todays lesson- how to set the classroom on fire!

[danialphaomega]

very interesting

[cowgoesmoo2]

Maybe it IS manganese, perhaps the video is just wrong.

[KiKadet]

@cowgoesmoo2 I did this same experiment two years ago (which is why I commented on this video), and it's magnesium that's used.

[cowgoesmoo2]

@KiKadet Oh, nevermind.

[prometheustwin1970]

Your teacher sounds just like Eric Idle (from Monty Python)

[GingleGangle1]

Is it possible with some carbonate?

[zaq147369]

the guy was saying manganese.

[douro20]

The magnesium burns so hot that it can strip the oxygen right out of the CO2. The result is magnesium oxide, carbon monoxide and pure carbon.

[montg2perfection]

hes saying manganese ribbon. he must mean magnesium?

[hexyournightmare]

heat + CO2 = CO + O2 and O2 is used to keep the Mg burning

[Valentino319]

yeah and then you get 2Mg + CO2 > 2MgO + C

the energy produced is enough to break the bonds between the carbon and the oxygen(s) in order for the magnesium to bond to it!

[flatboat70452]

I've heard that Titanium is the only element that will burn in Nitrogen. Try putting that fire out.

[vmelkon]

@flatboat70452 No, Mg will burn in N2 as well. In fact, you can burn Mg in air and it will form a little nitride. Dropping water on it make Mg(OH)2 and NH3 and you'll smell ammonia.

[oomblikkies]

The guy said that a metal fire can not be extinguished by CO2. Does this mean that all metals (iron, copper, zinc, etc) will burn in carbon dioxide?

[FibonacciPrower]

If you can first get them to burn in oxygen, then yes, I think so.

[Astrolounge]

Ah, the old desert sun reaction.

I'm a little bummed out it didn't show the part at the end where it will start pulsing with orange light.

[migitman999999]

i may be wrong, but if there is room for a spark to pass through, then couldn't oxygen?

[nirvanafan833]

not enough, magnesium just has the ability to strip O2 from CO2

[migitman999999]

if only the video had gone to the end of the reaction and there had been carbon left over

[1ukjunglednbraver]

its a redox reaction just like thermite isnt it

[nirvanafan833]

basically yeah, just like Al can reduce iron oxide to iron and use the oxygen, magnesium can reduce the carbon dioxide to carbon and use the oxygen

[doug123yt]

There is a strong outflow of carbon dioxide during the reaction, so no oxygen -- or other outside gasses -- can come in. The sparks are very hot pieces of carbon being ejected. The carbon granules remaining at the end of the reaction is red hot and will burn, but not readily. Please compare my version at watch?v=EFdiMp_HzeY

[punishedexistence]

Nice night light.

[InfinitiveNothing]

i noticed that too.

[KiKadet]

The professor keeps saying manganese instead of magnesium.

[SoronII]

Manganese is another way of saying magnesium.

^^

[KiKadet]

Manganese is atomic number 25 while magnesium is atomic number 12.

[SoronII]

Ah your right manganese is a different element.

I guess he is trying to abbreviate or something...

[agsjim]

The wire he torch in the beginning is Mg. He use that to ignite the Mn inside the block of dry ice.

[plinorph]

@KiKadet nice save after trying to be a smart ass :)

[DeadPixel91]

@KiKadet The correct term is in fact 'Manganese'

[KiKadet]

@DeadPixel91 Like I said before, it's not just a different term. Magnesium and Manganese are two completely different elements.

[DeadPixel91]

@KiKadet My mistake, It would seem my science teacher was a blithering idiot.

[14omega28ok]

@KiKadet because he sounds like hes british or something and the British are very very uneducated ( I know by experience)

[ConnorXV]

@14omega28ok of course, maybe you just visited the stupid area?.

[lolzinOo]

@14omega28ok u prick fuck off.

[14omega28ok]

@lolzinOo What you can't denie facts. and That is a fact.

[lolzinOo]

@14omega28ok LOL coming from an american. ok mate.

[apard7]

@KiKadet thats its proper name is maganese

[PenguinxVeNoM]

@apard7 no its magnesium



[marcusrmcd]

@KiKadet Perhaps that is because he is burning manganese, not magnesium.

[KiKadet]

@marcusrmcd NO. NO.

This reaction is a simple experiment involving Magnesium and restricting natural combustion with O2 to CO2. This is not possible with manganese.
