Mixtures and Compounds

[flyingsnowyman]

Did this today still have the piece of iron sulfide best to do the heating in the dark the orange glow is amazing

[MrSostanzialmente]

Can anybody write everything she says? I'm italian and I can't understand very well...:3

[iasedu]

Find a beaker of hydrochloric acid and show all your kids the amazing reaction of iron sulfide and HCl!

[thecoolfifi]

i love u !!!!!!!!! u just saved me from doing my homework <3 though i have no idea how to download it

[SonicBrawlChao]

240p grossness.

[lara2bailey]

My science teacher showed up this in class today!!!! :D

[UserIsAnFBIAgent]

And what can you do with that new element?

[eldy234]

It's not a new element, it's a compound

[987allison]

i want to see what will be the result if u mix all the 39 clues....can u try it??

[wolfie79x]

.....this vid is just crap.

[spotlightman1234]

oh my god i want the iron sulphide

[slamdunkd12345]

lol. this vid is in our science dimension cd.

[spongebob11725]

HEYA!!! ITS ME!!! :D!!!!!!

[hellokittygirl4ev123]

andrea?

[spongebob11725]

ahhhhhhh we have to look at this for our science hw.....<3 u miss.quigly!!!

[nemesis15ir]

thx alot it helped alot. no more confusion!

[Zephariah]

Thanks for sharing the video, it's clear and explained in simple English, great for introducing younger students to the concept of compounds. :)

[sugarbunnies101]

u ass if some1 wants 2 wach sciense vidios so wot if they do n im wachin this coz ov mi homework n sort ur life out ud haft 2 get laid 2 4get ur like coz il feel sorry 4 u when ur a drunk with no life n no job and no family so dont go criticising other people :D lol

[Einmaizter]

u guys r nerds

[ther0flcopter]

ahh yes u make a complete ass of ur self and make a stupid video of u humping ur mates good job (Y)

[Einmaizter]

well atleast i dont fuckin look at some nerdy videos about tengnoligy u dont have a fuckin life u have to get laid

[ther0flcopter]

HAHA wow must teach me of this new tengnoligy wow maybe i dont have a life u fellas have to keep me up to date with this stuff im soo behind. and dude if thats ment to mean technology this has nothing to do with technology, its chemistry? and this video is hardly about that it teahces u the difference be between mixtures and compounds which is more common sense! and i do have a life. who said u cant be interested in chemistry and have a life? thats something u have to teach me to (Y)

[Einmaizter]

dude just why would u waste ur time in watching this i mean i was in my school when i watched this and i had to watch it u spend ur time at looking at compines n shit seourisly what the fuck man i just dont get u

[ther0flcopter]

i like pyrotechnics...... look at my vids..lol companies? where did u get that from

[WhiteSox3x0Fan]

That was amazing.

[BarneySaysHi]

Add ironsulfide to hydrochlorid acid and the smell of rotting eggs is yours. We did that in chemistry and had to open some windows to let the smell out. Ahhh, the good old days in chemistry class!

[tijgerjorri]

Remember that hydrogen sulphide (rotten eggs) isn't just stinky. It's also highly toxic, about as toxic as hydrogen cyanide. I rather play with chlorine, ammonia or hydrogen chloride than with hydrogen sulphide.

[silendshade]

also remember that you can detect hydrogen sulphide in much lower concentrations then you can with hydrogen cyanide.

sulphide compounds are just commonly available and OTC, but as far as i know cyanide compounds aren't.

[tijgerjorri]

yes, but at high concetration, it kills you're smell, and you wont be able to smell it. Very dangerous.

[silendshade]

u mean the chance is that by the time u smell it it's already too late

[segarza]

Read up on basic industrial chemistry if you are really curious about the commercial uses of various chemical reactions. It's an awesome field of science to those who know.

[4524352353]

nice, but is it usefull?

[FryChicken]

This is basic chemistry. These basic concepts appear useless, but are later applied to chemistry which is invaluable to our current way of life.

[craynerd]

It is very important. It is difficult for people to understand this idea between mixtures and compounds and this experiment is the classic. Iron and sulphur mix, can be separated since the iron can be extracted using a magnet. When heated a chemical reaction occurs. This is no longer a mix of iron and sulphur but a completely new compound: iron sulphide

Useful, it depends who you are talking to....it`s useful to me or I wouldn`t be able to do my job

[craynerd]

This is the classic demo/practical used when we teach this. Shows how mixtures can be separated (in this example using a magnet) and compounds can not, they are chemically bonded!

Excellent video, great post.

Thanks

Cris

[fuzzrite]

actually,that is quite interesting...i though of a sweeet hypothesis while playing zelda that noobs would never understand...thanks for the vid,keep that shit rollin.
