Elementary Productions: Burning of Magnesium and properties

[DeTruZion]

What is the smoke produced from the burning Magnesium?

[TeamXtremeUK]

Lol

[mehnameisian]

Its like indiana jones, dont look at it

[Jessicu7697]

is the dissolving magnesium in HCl a chemical change?

[TheAdventurures]

That is Chuck Norris's candle

[Rockflier]

Use magnesium to light magnesium :D

[hiphopemanuel]

from were do you have dis magnesium band

[thomasgangsta]

I did this in school lol

[MrJervies]

fantastic... but how did you light the magnesium?with a normal lighter or other?

[JayseWeaver]

@MrJervies You can light it with any flame. Although try to light it from a distance, it burns really hot and it's bloody bright. It'll leave you seeing black dots for hours.

[georgelopezlover1]

@MrJervies yeah thats a torch lighter, but u can use just a standered bic or any other lighter, i just ordered a 75 foot long roll!

[nukeboy14]

WOOOO shiny

[SnowyWeety]

so...magnesium put into hot water would create hydrogen??

[spotlightman1234]

did the crucible survive the experiment?

[Nickblader1]

Where can i buy Magnesium ribbon ? thanks :)

[georgelopezlover1]

@Nickblader1 ebay, 75 feet is 10 bucks, glad to help

[hiphopemanuel]

@georgelopezlover1 o danks

[warstinger1234567890]

i wonder if you could use it as a flare of sum kind

[derman077]

lab coat reflection for the win

[lilgangstafoo94]

wait a minute if water doesnt extinguish it... then what does?

[mabakken]

Anything that cuts off the supply to Oxygen, such as sand or any other dry powder.

[locouk]

@mabakken Don't some powders become very volatile around heat sources? I've heard of a custard powder factory exploding due to a spark.

[mabakken]

@locouk Most dry powders can become flammable (not volatile) if they are spread out. When you extinguish a fire with powder, the powder will cover the ongoing combustion.

Also, the powders used in commercial fire- extinguishers is added a flame retardant (usually a Bromine compound) to prevent the powder from catching fire in any event.

[TeamXtremeUK]

@mabakken wat about water? cause u dont have oxygen to breath udner water with?

[mabakken]

@TeamXtremeUK That's true, but the burning Magnesium is a very powerful Reducing- agent, and is therefore able to rip the Oxygen in a water molecule off the Hydrogen, realeasing Hydrogen as a gas.

An analoguous thing happens if you put bunring Magnesium between two bricks of Dry- Ice: The burning Magnesium will rip the Oxygens off the Carbon Dioxide molecule, leaving elemental Carbon.

[butternutsquashpie]

@TeamXtremeUK also, putting water on something above 1000 degrees C will cause a steam explosion

and that shit's violent

[TheRyanatkinson]

@lilgangstafoo94 neither does carbondioxide. It's strange huh?

[SuperSlimshadie]

@lilgangstafoo94 cover it with a metal blowl so it has no air it will go out like a candle or u can put it in the friedge

[SuperSlimshadie]

@lilgangstafoo94 sand does it to

[metklok]

what's the gas that comes out of the magnesium strip when it's burning? is that just MgO as a gas or something?

[juicyjennna]

luv the experiment maybe you could tell me how and why it happens.

its my homework

[PowTheDel]

@juicyjennna because of all the photons that was released, since when the magnesium was heated it got excited and jumped to a higher energy level and when it was coming back to its ground state it emitted a bright light

[rcflight13]

Strange, last time I tried burning magnesium in science class it went some sort of greenish blue rather than white. Must have oxidized.

[cchj768]

that's because you didn't have a crucible filled with magnesium turnings. Copper burns with a geenish blue colour.

[TheMoni286]

why is the magnesium ribbon black? Isn't magnesium a silvery metal?

[Hellothere212121]

It's interesting to watch the camera try and compensate for the light changes.

[Theryolinator]

i got ammonia in my nose once;/ sniffed at a broken bag and i got nosebleed

[vitorix24]

I want buy magnesium! where i can get it?

[mewrox99]

@vitorix24

eBay or equivalent

[heckel29]

u can get blocks of it at walmart.There in the camping section.like a flint used to start fires.

[retret3565]

get it from galiumsource . com

[vitorix24]

i'm form portugal

[Zephariah]

Thank you for sharing this video, it is exactly what I need to introduce my students about chemical reactions !

[asteriscotriangulado]

Woow! that was awesome! now i know more why i am studying farmaceutical chemistry.

YOur vids are awesome.

[kuostis14]

cool vid man, keep it up *thumbs up*

[b43e65f77]

I think this is possible that when you put some carbonate on the burning magnesium.

[sebastianFIN]

is it possible to make ammonia solution by dumping Magnesium oxide/nitride in water? if so does ammonia react whit MgO? i did this experiement myself yesterday, and i got a clear solution whit strong ammonia smell. but i want to know is this pure ammonia :) hopefully you understood my "enclish" :P

[mabakken]

Magnesium Oxide does not react with water to give ammonia, but Magnesium Hydroxide.

If you put Magnesium Nitride in water, it will evolve Ammonia gas, and although that Ammonia solves pretty well in water, you wouldn't get a very concentrated solution.

The ammonia formed is decently pure =)

[sebastianFIN]

yea i knew oxide doesn't react whit water giving ammonia :P but i was thinking if MgO reacts whit ammonia that is formed in the solution, because i do now that ammonia attacks copper and other metals. anyways i have now a big bottle of "dilute ammonia" and im gonna do some "tests" whit it ;d

[bla287]

Ammonia doesn't attack elementary copper, maybe you were thinking of the dark blue complex, which is formed when you add NH3 to a solution of a Cu(2+) salt? In this case, square-planar [Cu(NH3)4] is formed, which absorbs much more light than the aquo-complex and thus is dark blue.

[bla287]

If you also have HNO3 at home, you can do the experiment too: Just dissolve some Cu wire in HNO3 (beware of the NO2 fumes!), dilute it with min. double amount of water (color should change from green to blue), then slowly add some NH3 (be careful, neutralization reaction is very vigorous!)

[sebastianFIN]

yes i meant that :d

[bla287]

oops I meant [Cu(NH3)4](2+)

[MysticVulture]

Ammonia is 10 on the pH scale (basic), and it's also toxic. To those retards who think ammonia is a drink, you are dead wrong. Ammonia is highly poisonous, while drain cleaner is both poisonous and caustic (burns skin on contact).

[somekachtyname]

omg that was sooo cool

[derkozten]

Would sound stupid, but I never asked how looks Mg salts when burned.

Is Mg(2+) ion as bright as Mg metal?

[mabakken]

Not a stupid question at all, as you usually encounter "known" alkali and alkali earth metal salts like Sodium and Calcium.

Mg(2+) actually does not emit radiation in the visible spectrum, and therefore looks colorless in a flame test. =)

[asd52320032003]

good work

Now will try to steal some from my schools chem lab JK JK!

[liquidgrain]

what supplier?

[mabakken]

A norwegian one =)

[nulladiessine]

well supplied lab man

[FP791]

not even close

[frizspin175]

I tried putting water on a burning magnesium strip, but it just went out

[mabakken]

Try a little more magnesium, and before you drop some water on, let it burn steadily =)

[atos90]

er du norsk

[mabakken]

Ja, d e eg :)

[atos90]

where did you buy the magnesium

[mabakken]

From a chemical supplier.

[davidkoster]

Very good video;al your video's are good

Congrulations

[Basco36]

thankyou for posting this, finally my questions are answered about this reaction.
