carbon dioxide can't breakdown into hydrogen and oxygen. So, I was wondering, are you referring to water condensation that turns into ice that then breaks down into hydrogen and oxygen? Also, it is possible that the CO2 catalyzes the reaction between Fe2O3 and Al because of the acidic nature of CO2; then, after catalyzation, it vaporizes because of the heat that is released; then the reaction becomes self-sustaining and explodes because of the CO2 vapor, and the force of the reaction between Fe2O3 and Al.
EXACTLY!! Carbon dioxide is CO2, NO Hydrogen jn it. Also, it looks like what they call dry ice is floating on top of the liquid in the pan (at 7:25). Dry ice does NOT float, it is denser than water. Someone should check some facts, maybe??

In #4 you'd better use a penny that's 1981 date or earlier, because later pennies are zinc with a copper plating. Actually in 1982 year only, pennies were produced that were both mostly copper, such as the earlier ones, and zinc with copper plating.

12:10 I remember having hand warmers filled with this stuff. They were a plastic bag filled with sodium acetate. You would boil the bags in water until all of the sodium acetate was melted, then you would set the bags out to cool. Once cooled the sodium acetate stayed a liquid until it was given a bit of a bang. Inside the bag was a metal disk and you would "click" the disk to start the stuff freezing. The freezing temperature of sodium acetate is quite warm, and the stuff actually warms up to freeze. And the now solid substance stay warm for a while. Water will do the same thing. If you super cool water, lower the temperature of water to below the freezing point, then if you give it a shock (like banging it on the counter) the water freezes vary quickly. But here's the weird part. Water only freezes at 32 degrees. It won't freeze at a temperature lower than 32 degrees. In theory if you can get liquid water below it's freezing point you can just keep cooling it more and more. But the farther you cool it below it's freezing point the easier it is to make it flash freeze. Eventually something will happen and the water will flash into ice. But it actually heats up to do this. If say you cool your water to 20 degrees then bang it, the water will heat up to 32 degrees. You can't feel this warming, because 32 degrees is still very cold to our senses. But you can measure it.
well.... you're pretty close. As you heat the sodium acetate it DISSOLVES in the water inside the packaging. It remains dissolved even as it cools. At this point it is a supersaturated solution. It will stay supersaturated and will not precipitate until you "help" it come out of the solution. This help is the small metal disk - as you bend it or manipulate it somehow you are creating a nucleation point. This nucleation point is a point where the first crystal can begin to form - and then more crystals can form on this one and so on until the entire plastic bag is solid with sodium acetate crystals. The same thing happens when you 'bang on" the super cooled water you mention - you're creating a nucleation point so the water can form the first few crystals of freezing.
Trilodide ah yes , I painted it on all the light switches in the lab at my high school in 1968 . When my classmates turned on the lights , a nice little bang and a black stain on the switch plates. Good times !
Hi - I'm 60 yrs old - Had a chemistry set as a kid, given in 1970 - really quite safe. Guess what? I became a degree qualified Chemist in 1983. A shame such things are not accessable now on health & safety grounds as it does set a young mind on a path...
At the time I was a teen, society was far less paranoid. I was able to go to a chemical supply and buy 30% ammonia and solid iodine crystals. The man who rung up the sale just looked at me and told me not to make more than a teaspoon at a time. Advice which I followed. I also was smart enough to wear safety glasses and a grinding mask while messing with it. Yes it would go off for any reason or none at all once it was dry. It's harder to buy the iodine now because apparently it's also considered a precursor for illicit drug production.
I purchased chemicals under a Don’t Ask, Don’t Tell policy. The guy at the pharmacy never asked me what I wanted saltpeter, sulfur, and charcoal for - because he knew. I made it out of childhood with all of my body parts intact, which wasn’t a given.
I once made a huge batch of sodium acetate for some glacial acetic acid and I decided to see how hot the hot ice gets. The huge batch was ready to go so I threw on a nitrile glove and stuck my hand in. It began to warm and felt nice but after a few moments after I noticed the warm it became unconformable and i removed my hand. Very cool that it releases more heat than you would think. Nitric acid is always crazy i make fuming nitric acid then dilute it as necessary but most show the typical nitrile glove with fuming nitric acid and it catches on fire. I hate working with it because if I get it on my skin when you neutralize it with baking soda your skin goes from yellow to orange as it oxidizes keratin and for whatever reason the neutralization makes it worse.
Cesium in water explodes due to rapid charge build up, a coulombic explosion, not because of the heat and H2 produced. The heavaly shielded valence electrons are released into the water much faster than the dissociation of sodium ions from the metal. This results in rapid charge buildup, followed by expansion, which exposes more metal and results in further charge build up. It is the repulsive force from all the nearby positive charges that created the explosion (supersonic expansion)
they are both highly electropositive..Na and Cs...Valence theory is quite outdated. MO theory is more appropriate : S,P,D,F,L orbitals describe the statistical density of electrons and e- spin pairing is more important than charge attraction in explaining situations like this; however, I am 67 and out of my 'element' as I'm an organic chemist. I will have to defer to an INorganic or perhaps a Radio-chemist to explain a rxn I would initially have expected to be 'in line' [period humor] with an electropositive reaction with water in the same period as Li, K Na etc. The rest of the explanation is unsuited to this forum unless we should start a new thread? I'll do some reading and see what I can extract from this curious mini detonation or supersonic expansion of water gas. It occurs to me the 'explosion' part is the same as though it came from an exothermic release of rapidly expanding gas [water vapour] A rupturing tire is exploding as surely as a chemically induced release of supersonic gas by thermal energy release.
@@quitolemutt1062 There's an interesting papery published in 2015 (Coulomb explosion during the early stages of the reaction of alkali metals with water - Nature chemistry) that goes over the proposed mechanism and explains it better than I attempted above. Supper jealous of the research, looked like a very fun project playing with a liquid alloy of sodium and potassium. The work showed it was the sodium/potassium droplet that was expanding supersonicly, not gas generation from the heat of the reaction that produced the explosion. H2 gas is also generated and combusts if O2 is present, but the reaction still moves forward with the same energetics even in the absence of O2, showing that H2 explosion is also not the main source of the explosion. I agree, MO theory could provide much better insights into this classical reaction. But as an aspiring organosynthetic chemist, MO computational work has always been a bit outside of my wheelhouse, and I find the more classical description of charge repulsion easier to digest.
I had a fraternity brother who was a chemistry major. He made a batch of Nitrogen Triiodide one night and sprinkled it on steps and sidewalks all over campus. The next few days were quite exciting.
12:15 It’s exothermic, not endothermic. EXOthermic means that heat is released in the reaction, while ENDOthermic means heat is absorbed. You can remember it if you think of EXO as EXIT

Need to have the script proofread for errors before handing it over to the narrator. I've spotted a few important errors. Asside from the errors, was a pretty interesting video.
The Cesium reaction is wrong. It does not explode because of the hydrogen. The explosion is due to the Columbic forces of charged particles. The reaction isolates positive charges exponentially until the charge is great enough to overcome the molecular cohesion of the cesium, causing it to explode.
Are you, I don't know, a chemical engineer? I've never really been interested in chemistry before. After reading your articulate and concise comment/explanation, that changed. Thank you. 😊
@@DreadX10 No. I do know there was an experiment around 2012 or so where they made a metal alloy with sodium and potassium that was liquid at room temperature, then dropped it through a flask of xenon into water. It was filmed with a very high-speed camera, and it was clear from that experiment that previous assumptions about the reaction were wrong and needed to be re-assessed. Looking more closely at the chemical reaction taking place, it was observed that like charges were isolated on the material at an exponential rate. As like charges wish to be as far away from each other as possible, they eventually tear the substance apart in a catastrophic explosion. ** Edit: Correction, the atmosphere in the flask was argon, not xenon.
@top fives it would be nice if you'd include the sources where you got the footage from... some of them I recognise from youtube clips I've seen years ago...
@12:18 you say the sodium acetate reaction is ENDOTHERMIC but then say warmth is emitted from the liquid. that is EXOTHERMIC. endothermic reactions get cold not hot.
There are tons of inaccuracies. Kinda sad. Like how he mentions dry ice breaks down to hydrogen and oxygen.. or when they show a picture of red phosphorus when he's talkin about bromine gas.
The definition of endothermic is, ‘a process accompanied by or requiring absorbing heat’, meaning the chemical process the liquid goes through would absorb heat, and emit it so what he said is correct. The definition of exothermic is, ‘a process accompanied by or requiring the release of heat’. So if something is releasing heat, it is cooling down. Remember releasing heat is not the same as emitting heat!
@@invisiblekid7374 You're wrong. Think about it - absorbing heat means getting it from the environment - such that the environment has to have less heat, i.e. colder. If you absorb heat, you get colder. Ice absorbs heat to melt - so feels cold. When steam condenses it releasing heat, so can burn you. These demonstrate change in heat vs change in temperature. Added examples, burning is exothermic - so releases heat/is hot. Dissolving ammonium nitrate is endothermic, so it get's cold (It's used in cold packs where you pop the liquid internal balloon and the dissolving NH4NO3 causes it to get cold).
Little correction: Dry ice is carbon dioxide so, it does not break up into hydrogen and oxygen but to carbon and oxygen. And yes, the oxygen is released in very active single-atom state and therefore probably reacts with aluminium, causing the ignition and ultimately explosion.
The thermite information was mostly all wrong. You've got to do a lot more than "touch it with a match" to light the stuff. You need a LOT of heat to light iron thermite. Burning magnesium heat or a torch for 30 seconds might do it, but not touching it with a flame. Also it has to be lit before you cover it with dry ice. Simply covering thermite with dry ice, or even water ice will Not set it off. If its burning and you cover it with dry ice, it will react yes.
You sound like you've tried. I can't tell you how many hours I spent, as a teenager, trying to get iron thermite to light. A simple magnesium ribbon never worked for me. It wasn't until I was older that I found out other thermite types could start easier and be used as ignition mixtures for iron thermite.
There are tons of inaccuracies in the video from the actual visuals to the script.. not sure if they ever heard of fact checking or a pre-screening but oh well.
Great collection. I noticed the lid left off the container, right next to the hot reaction going on in the Potassium Chlorate/ Gummy Bear demo. I see this a lot, and am not surprised this was the last experiment you included. Is that professional still around for your next video?
See the comments immediately above and below your post about that, although I'll grant you that they did a good job as far as making an interesting video with interesting facts. Just not all of them were accurate facts.

@Nick McGinley next time, before you claim someone is wrong, you should check the definitions of endo and exothermic reactions. In both instances of endothermic reactions he was correct because it requires heat i.e. the heat from your hand or open flame... hence the reason for the weird designation for the first one.
@@maniacaljedi2848 You are 100% wrong. Exothermic reactions liberate heat, endothermic reactions absorb heat. I do not need to check because I am a scientist with an education. And you have no idea what you are talking about. Activation energy is not what is referred to as exo or endothermic. Those designations refer to the temperature of the reaction products once the reaction has occurred. If they get hotter, it was exothermic, if they get colder, it is endothermic. Period. Do what you suggested and look it up, and stop being a jackass.

@3:50 the chemical that is presented as great for rocketry is misleading. The rockets can ONLY work in the atmosphere where there is air and moisture with which to react, not in the vacuum of space.

He then tried to pat the burning chemical out with his hand and ended up with a chunk of burning potassium embedded in his hand.

Eventually he got the stuff out of his hand but had to visit the school nurse. He ended wearing a bandage on that hand for quite some time.

In #4 you'd better use a penny that's 1981 date or earlier, because later pennies are zinc with a copper plating. Actually in 1982 year only, pennies were produced that were both mostly copper, such as the earlier ones, and zinc with copper plating.
He did, I checked. It was a 1969 penny. I checked because I was thinking the same thing. :)
Fun fact: you can take a zinc core penny, scratch a hole through the copper jacket, and plop it in a solution of hydrochloride. The HCl will react with the zinc and youll be left with a clean copper foil jacket.

Very interesting, informative and worthwhile video.
its so incredable ,this video is special
12:10 I remember having hand warmers filled with this stuff. They were a plastic bag filled with sodium acetate. You would boil the bags in water until all of the sodium acetate was melted, then you would set the bags out to cool. Once cooled the sodium acetate stayed a liquid until it was given a bit of a bang.
Inside the bag was a metal disk and you would "click" the disk to start the stuff freezing.
The freezing temperature of sodium acetate is quite warm, and the stuff actually warms up to freeze. And the now solid substance stay warm for a while.
Water will do the same thing. If you super cool water, lower the temperature of water to below the freezing point, then if you give it a shock (like banging it on the counter) the water freezes vary quickly.
But here's the weird part. Water only freezes at 32 degrees. It won't freeze at a temperature lower than 32 degrees. In theory if you can get liquid water below it's freezing point you can just keep cooling it more and more. But the farther you cool it below it's freezing point the easier it is to make it flash freeze.
Eventually something will happen and the water will flash into ice. But it actually heats up to do this.
If say you cool your water to 20 degrees then bang it, the water will heat up to 32 degrees. You can't feel this warming, because 32 degrees is still very cold to our senses. But you can measure it.
well.... you're pretty close. As you heat the sodium acetate it DISSOLVES in the water inside the packaging. It remains dissolved even as it cools. At this point it is a supersaturated solution. It will stay supersaturated and will not precipitate until you "help" it come out of the solution. This help is the small metal disk - as you bend it or manipulate it somehow you are creating a nucleation point. This nucleation point is a point where the first crystal can begin to form - and then more crystals can form on this one and so on until the entire plastic bag is solid with sodium acetate crystals. The same thing happens when you 'bang on" the super cooled water you mention - you're creating a nucleation point so the water can form the first few crystals of freezing.

At the time I was a teen, society was far less paranoid. I was able to go to a chemical supply and buy 30% ammonia and solid iodine crystals. The man who rung up the sale just looked at me and told me not to make more than a teaspoon at a time. Advice which I followed. I also was smart enough to wear safety glasses and a grinding mask while messing with it. Yes it would go off for any reason or none at all once it was dry. It's harder to buy the iodine now because apparently it's also considered a precursor for illicit drug production.

I once made a huge batch of sodium acetate for some glacial acetic acid and I decided to see how hot the hot ice gets. The huge batch was ready to go so I threw on a nitrile glove and stuck my hand in. It began to warm and felt nice but after a few moments after I noticed the warm it became unconformable and i removed my hand. Very cool that it releases more heat than you would think. Nitric acid is always crazy i make fuming nitric acid then dilute it as necessary but most show the typical nitrile glove with fuming nitric acid and it catches on fire. I hate working with it because if I get it on my skin when you neutralize it with baking soda your skin goes from yellow to orange as it oxidizes keratin and for whatever reason the neutralization makes it worse.
WTF?! How much heat id you think it was releasing?! Also what lab do you work in so I can stay the hell away from it?!?!
In the video he called this an endothermic reaction, so I am assuming he meant exothermic instead.
For anyone wondering, the video at the very beginning was a pyrophoric zinc compound, video is on PeriodicVideos channel.
Cesium in water explodes due to rapid charge build up, a coulombic explosion, not because of the heat and H2 produced.
The heavaly shielded valence electrons are released into the water much faster than the dissociation of sodium ions from the metal. This results in rapid charge buildup, followed by expansion, which exposes more metal and results in further charge build up. It is the repulsive force from all the nearby positive charges that created the explosion (supersonic expansion)
they are both highly electropositive..Na and Cs...Valence theory is quite outdated. MO theory is more appropriate : S,P,D,F,L orbitals describe the statistical density of electrons and e- spin pairing is more important than charge attraction in explaining situations like this; however, I am 67 and out of my 'element' as I'm an organic chemist. I will have to defer to an INorganic or perhaps a Radio-chemist to explain a rxn I would initially have expected to be 'in line' [period humor] with an electropositive reaction with water in the same period as Li, K Na etc. The rest of the explanation is unsuited to this forum unless we should start a new thread?
I'll do some reading and see what I can extract from this curious mini detonation or supersonic expansion of water gas. It occurs to me the 'explosion' part is the same as though it came from an exothermic release of rapidly expanding gas [water vapour] A rupturing tire is exploding as surely as a chemically induced release of supersonic gas by thermal energy release.
@@quitolemutt1062 There's an interesting papery published in 2015 (Coulomb explosion during the early stages of the reaction of alkali metals with water - Nature chemistry) that goes over the proposed mechanism and explains it better than I attempted above. Supper jealous of the research, looked like a very fun project playing with a liquid alloy of sodium and potassium. The work showed it was the sodium/potassium droplet that was expanding supersonicly, not gas generation from the heat of the reaction that produced the explosion. H2 gas is also generated and combusts if O2 is present, but the reaction still moves forward with the same energetics even in the absence of O2, showing that H2 explosion is also not the main source of the explosion.
I agree, MO theory could provide much better insights into this classical reaction. But as an aspiring organosynthetic chemist, MO computational work has always been a bit outside of my wheelhouse, and I find the more classical description of charge repulsion easier to digest.
I had a fraternity brother who was a chemistry major. He made a batch of Nitrogen Triiodide one night and sprinkled it on steps and sidewalks all over campus. The next few days were quite exciting.

Voice over is over the top.
The Cesium reaction is wrong. It does not explode because of the hydrogen. The explosion is due to the Columbic forces of charged particles. The reaction isolates positive charges exponentially until the charge is great enough to overcome the molecular cohesion of the cesium, causing it to explode.
Thanks, that mistake bugged me. Glad you flagged it.
Are you, I don't know, a chemical engineer? I've never really been interested in chemistry before. After reading your articulate and concise comment/explanation, that changed. Thank you. 😊
Have you seen Thunderf00t's experiment on sodium and potassium?
@@DreadX10 No. I do know there was an experiment around 2012 or so where they made a metal alloy with sodium and potassium that was liquid at room temperature, then dropped it through a flask of xenon into water. It was filmed with a very high-speed camera, and it was clear from that experiment that previous assumptions about the reaction were wrong and needed to be re-assessed. Looking more closely at the chemical reaction taking place, it was observed that like charges were isolated on the material at an exponential rate. As like charges wish to be as far away from each other as possible, they eventually tear the substance apart in a catastrophic explosion. ** Edit: Correction, the atmosphere in the flask was argon, not xenon.

Very good video
@12:18 you say the sodium acetate reaction is ENDOTHERMIC but then say warmth is emitted from the liquid. that is EXOTHERMIC. endothermic reactions get cold not hot.
There are tons of inaccuracies. Kinda sad. Like how he mentions dry ice breaks down to hydrogen and oxygen.. or when they show a picture of red phosphorus when he's talkin about bromine gas.
The definition of endothermic is, ‘a process accompanied by or requiring absorbing heat’, meaning the chemical process the liquid goes through would absorb heat, and emit it so what he said is correct. The definition of exothermic is, ‘a process accompanied by or requiring the release of heat’. So if something is releasing heat, it is cooling down. Remember releasing heat is not the same as emitting heat!
@@invisiblekid7374 You're wrong. Think about it - absorbing heat means getting it from the environment - such that the environment has to have less heat, i.e. colder.
If you absorb heat, you get colder. Ice absorbs heat to melt - so feels cold. When steam condenses it releasing heat, so can burn you. These demonstrate change in heat vs change in temperature. Added examples, burning is exothermic - so releases heat/is hot. Dissolving ammonium nitrate is endothermic, so it get's cold (It's used in cold packs where you pop the liquid internal balloon and the dissolving NH4NO3 causes it to get cold).
Excellent video - Keep it up!
Little correction: Dry ice is carbon dioxide so, it does not break up into hydrogen and oxygen but to carbon and oxygen. And yes, the oxygen is released in very active single-atom state and therefore probably reacts with aluminium, causing the ignition and ultimately explosion.
He was also incorrect about a flame setting off the thermite. It take a very high temp to do that....usually a magnesium rod flame.
@@fireballxl-5748 true, but provided with the right catalyst the reaction may start without high temp.

The thermite information was mostly all wrong. You've got to do a lot more than "touch it with a match" to light the stuff. You need a LOT of heat to light iron thermite. Burning magnesium heat or a torch for 30 seconds might do it, but not touching it with a flame. Also it has to be lit before you cover it with dry ice. Simply covering thermite with dry ice, or even water ice will Not set it off. If its burning and you cover it with dry ice, it will react yes.
You sound like you've tried. I can't tell you how many hours I spent, as a teenager, trying to get iron thermite to light. A simple magnesium ribbon never worked for me. It wasn't until I was older that I found out other thermite types could start easier and be used as ignition mixtures for iron thermite.

@Nick McGinley next time, before you claim someone is wrong, you should check the definitions of endo and exothermic reactions.

Pretty much every rocket carries an oxidizer on board, so your statement doesn't make a lot of sense. Anyhow, the wikipedia entry on it only has a short reference to use in rocketry.

I remember a secondary school chemistry teacher at my school showing us how potassium reacts with water. It reacted and exploded throwing a small chunk of burning potassium onto his desk. He then tried to pat the burning chemical out with his hand and ended up with a chunk of burning potassium embedded in his hand. Panicking, he decided to put out the chemical by running it under some cold water. But it was potassium and didn't like that very much. Eventually he got the stuff out of his hand but had to visit the school nurse. He ended wearing a bandage on that hand for quite some time.
