Calcium Carbide Reacting with Water

[Istudynak1d]

sick video dude subbed, i loved it! i think you got such a violent rxn because first of all it's an exothermic rxn so it gives off a lot of heat, but also you put a LOT of water lol in my class we only put drop by drop and it gave off a ton of acetylene gas, but very cool video, gj.

[katlynk90]

it actually produces methane gas not acetylene

[Ch3mG33k]

@katlynk90 Nope, it's acetylene: CaC2 + 2 H2O → C2H2 + Ca(OH)2

[OSChrome]

Seagulls explode if they have calcium carbide... :L

[Ch3mG33k]

@98Kestral All to do kinetics. Gotta love collision theory <3

[TrueGreatness73]

be careful around some animals as that gas can kill them

[bboygif]

"...which hopefully won't kill me"

hahah, made me hit the like button

[mewrox99]

CaC2 is a lot of fun! Tried making metal acetylides before?

[420bruiser]

where im from we put it in a paint can

[donRefriLvr]

thanks for thee video it really helped me understand what i was studying for in my class! :D

[dragoncoolguy]

so where's the limwater. because limewater is one of the products

[a4d2d0]

WHY do you have all that stuff in your room?

[smallenginemods]

that was acually pretty decent but imagin it you got one of them huge baloons and did that

[29CFR1926]

Calcium carbide with moisture creates corrosive calcium hydroxide. This is how you see a lot acetylene produce here (ethyne). This is a serious fire hazard compounded for the potential to inhale the gas that causes depression on the central nervous system, in addition to the fire hazard.

[Ch3mG33k]

@29CFR1926 Was there any point to all of that or were you just stroking your e-pen0r?

Seriously, comments like this are the reason why I hate posting chemistry videos.

[Keira2694]

@Ch3mG33k Why?Maybe he/ she commented in the aid for others. Nothing wrong with it..

[911GuiltyJerk]

Is the reaction exothermic? I'm guessing not based on the way you just grabbed the flask, but I kinda want to know lest I burn myself.

Also is that miner's grade? And is the water distilled or anything? Or just tap water?

Here's to being a good student :)

Holy Cow!

[WICKEDSLIP15]

How i can by Calcium and sodium?

unitednuclear [dot] com

It's where all mad scientists and terrorist get there nuclear products online.

[xR0WDYx]

nice and clean burning gas..lolz we filled a trashbag full of it freshman year in college...burn slow...covered everything is soot....bad bad idea....department still doesnt know what it was

[captainkeewl]

thank you for moving the balloon first i thought i was going to have to watch another pore Erlenmeyer Flask die :(

[jonsherblom]

i love how he backs away hahahaha

[charlieocheerio]

haha! no! im only 13. i dunno wat type of calcium it was, i was only guessing it wud be tht. oh well...the reaction in my science class was better!

[charlieocheerio]

u call tht energetic. it was freakin' boring! u named tht wrong it shud be science experiment-lullaby version.

in our science class we mixed PURE calcium with water, it made a pink flame and flew out of the bowl so fast someone yelled shit.

THAT, was nothing.

[Ch3mG33k]

Pure calcium with water is a less energetic reaction because the products created have less entropy than the starting reactants. It is thermodynamically favored because ∆H is extremely negative. As a result, the reaction is more energetic.

You do understand thermodynamics, right?

Q.E.D.

[xR0WDYx]

bah: just look at the kinetics: but I like the fact you arnt shy to post a bit of p-chem

[xR0WDYx]

lol. pure calcium is boring. it bubbles to give diatomic hydrogen. may be high on a set activity series, but still has a low rate of reation. Potassium on the other hand.....

[nitrex]

I have lots of Calcium Carbide, i normally use it to produce Silver Acetylide, which is a known primary explosive. Calcium carbide has an interesting property of releasing Acetylene gas.
