Elementary Productions: Burning of Magnesium and properties

Magnesium turnings are placed in a crucible. The turnings are ignited by the use of Magnesium ribbon.
Properties of burning Magnesium and reaction products are demonstrated.

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.

@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.

@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.

cool vid man, keep it up *thumbs up*

[Zephariah]

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

[DeTruZion]

What is the smoke produced from the burning Magnesium?

[SuperSlimshadie]

@lilgangstafoo94 sand does it to

[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

[TeamXtremeUK]

Lol

[butternutsquashpie]

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

and that shit's violent

[mehnameisian]

Its like indiana jones, dont look at it

[Jessicu7697]

is the dissolving magnesium in HCl a chemical change?

[TheRyanatkinson]

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

[TheAdventurures]

That is Chuck Norris's candle
