>>"What is just four oxygens stuck together?"
As a chemist, the answer is 'a very very angry molecule'
O3 being ozone, what's the 4th O doing?
surely not as angry as 14 Nitrogens stuck together with only a couple of Carbons to _"stabilize"_ it
@@alext8828 Probably finding any excuse it can to leave. My guess is if for some chance this did happen to exist it would immediately fall apart and make two O2 molecules
O-O-O-O.....
Isn't that the Orgasm molecule?
@@MRTransportVideosit's going to squirt all over the place alright
"If helium is so rare, why are we filling party balloons with it?"
And that, RCE, is an actual, honest to god issue. Helium reserves were nationalized decades ago but our (US) companies forced the feds to open up the reserves for their own interest and subsidize the cost of helium prices, otherwise the cost of helium would be astronomical. Also because of that, we're slowly running out of helium that is needed for vital uses.
well it mainly comes downto helium actually being rare in the first place. It is only really found in underground pockets next to radioactive sources.
Look, just because you need an MRI doesn't mean i should have to forego my squeaky voice.
Ah yes. Capitalism at its finest. Wasting a rare and value resource on frivolous things just to make a quick buck. Why do I suddenly hear the song "How Bad Can I Be" playing in my head?
you tell rce thatjeff7550
Helium is not rare outside of earth. The issue is that there is no way (yet) to create helium, it’s produced as a byproduct of radioactive breakdown. The thing is that every Helium molecule wants to go to space - it’s always it’s final destination. We are just trying to make that path longer
I think it would be more fun if it told you the name of the molecule you just made, and the fun fact was about that molecule.
Yeah exactly!
One of the common molecules you make is formaldehyde. Formaldehyde fun!
No doubt. I thought the premise of the game could be really neat but it doesn't seem to have very much actual science.
This.
The first game did that, it's very confusing to see they no longer do that here.
13:30 A degree in chemistry gets you to the point where you start turning cotton balls into cotton candy, your own urine into artificial sweetener, toilet paper into moonshine, vinyl gloves into hot sauce, paint thinner into cherry soda, and calling that a meal!
I see we watch the same psychotic chemist.
The NileRed slander 🤣🤣🤣
and styrofoam into cinnamon now
Styrofoam into SPICY **ILLEGAL** Cinnamon, if combined with other chemicals @anarchosnowflakist786
@@uribove is it slander if it's true? 🤔 I mean let's be real, the worst smell experiment really proves the point.
Two atoms are talking about their recent experiences.
Atom 1: "I think I've lost an electron!"
Atom 2: "Are you sure?"
Atom 1: "I'm positive!"
ha ha how funny, you get it, cuz an electron is negative hahahahahahahhahahahahahajahahahahajhahahahahhahahahahaha
Atom 3: "I think someone has lost an electron because I'm negative."
Atom 4: Shouldn't You Be Happy? I mean, You Cl atoms always Want to get One more. By the way, Anyone wants 2 Of my Electrons? They Just Make Me Unstable Being there.
I haven't studied chemistry in over 30 years...wish the game would tell us what molecules you are building...learning opp lost 🙁
later in the game or an update, you can kinda!
4:00 I know this one, America has been liquidating its supply of helium for quite some time, selling it at a very low price because the government simply has no use for it anymore (Idk what they even needed it for in the first place), which means that due to supply and demand things like helium balloons for birthdays were a viable product. Once they sell it all though then helium balloons will be super expensive.
Also that fact about helium on the moon is worded pretty poorly. The only reason why we would want to go to the moon for helium is because theres lots of helium-3 there. The helium we use normally is He-4, which coincidentally makes up 99.99% of helium on earth. The only practical use for lunar He-3 would be as a fusion feedstock (right now we use tritium, which is radioactive and apparently quite difficult to work with), but considering we haven't even solved sustainable fusion yet, its a moot point to mine it on the moon
Helium is actually vital for hospitals because it's needed to cool MRI machines and the US government selling off the stocks is to the detriment of healthcare. Helium should be strictly controlled and not allowed to escape, because most Helium that escapes into the environment is lost and can't be recovered
Ngl watching your brain fall apart at naming h2o2 had me in pieces 😂
HYDROGEN PEROXIDE
dihydrogen dioxide
What do acid and the military have in common?
They both neutralize bases
Two chemists walk into a bar, the first asks for h2o, the second asks for h2o too, and dies
Why do the words "face palm" suddenly come to mind? 😀

But he aent no more!

Some notes for those interested about Matt's questions
1:20 Bonds sort of like that exist, but you probably mean the 1.5 (actually 1.33) _bond order_ in CO3(2-) or molecules like that.
1:35 Some elements are rare on Earth, some in the universe, and some in both. Some elements are also not in large amount on the surface of Earth, but may be in larger amounts on asteroids or under a planet's surface. Some elements occur naturally in rocks and minerals that are hard to refine into the element. Some elements are the combination of several or all of the above. That makes them hard to obtain, expensive to mine, extract, and use, and so they are "endangered" in that they are hard mine, extract, and their ores are in limited amounts on Earth.
3:45 Helium is not made by a lot of natural or artificial processes on Earth. It is mostly made by nuclear reactions (fissions and fusions), only some of which can happen on Earth, so much of Earth's helium still comes from the sun and universe around us. As it is a very light and small (almost as much as hydrogen) element and chemically practically inactive (it comes from the group noble/inert gases on the right of the periodic table), so it can be used in a lot of ways, but it also easily slips through all of atmosphere (and all sorts of other materials, even solid) to the edge and then out of it. It is also quite easy to find still, and to make in some smaller quantities. But you are right, it still does not make much sense. Similar to indium and other elements and chemicals. But humans often don't make too much sense.
4:14 Formaldehyde (systematically methanal). Similar to methane (hence the systematic name), but 2 hydrogens are replaced with 1 double bond to 1 oxygen.
6:50 Water is technically systematically named dihydrogen monoxide (but even in systematic nomenclature the mono- prefix is often omitted). This molecule is called peroxide and not dioxide, because the prefixes express the number and types of bonds present. A per-oxide has a O-O bond, a di-oxide is just oxide twice, and oxides have always 2 O-X bonds (X being any other element, but O). It helps chemists to imagine the molecule, even if there are no alternative bonding structures really possible/probable.
7:35 Some of the most efficient molecules to bond with many metals are found in biochemistry, so often even in our bodies. That is also part of the reason, why are so many metals toxic (like cadmium, lead, or mercury). They change some molecules they bond to well, which then harm us, or they displace those metals we need (like iron or calcium) from molecules, that bond to those beneficial metals.
8:00 Close. That would need one more oxygen atom. This is nitrous acid. A less stable and more dangerous acid of nitrogen.
8:50 Hydrazine is similar to and derived from ammonia. Its use in rocket fuels is partly because of the stability of N2 molecules and the reactivity of N-H bonds.
11:40 Iron(III) oxide gets easily hydrated by water, even just the moisture in the air. It makes iron(III) hydroxide, which is also reddish brown and quite similar in many ways to the oxide. In fact, iron(III) compound are often red, brown, or orange-yellow.
12:05 The plus probably means it's a hydrogen atom without one electron, thus a cation H+. As a matter of fact, hydrogen has only one proton and one electron, so a hydrogen cation is often (except for the isotopes of hydrogen, deuterium and tritium, which have a proton and some neutrons) just a lone proton.
12:20 As with the 1.33 bond order in CO3(2-), electrons can be shared in a bond between 2 atoms in all sorts of weird ways. Technically, one such bond could between a hydrogen atom and a hydrogen cation, a bond consisting of one electron of the bond order 0.5.
13:30 Ions, and ionic bonds specifically, seem relatively easy on the elementary or high school level, but is in fact quite more complex to the extent, that some aspects of them are still not fully understood and are still a bit debated today.
14:55 Cat-ions, an-ions. You say it like it's built - _ion_ plus the prefix cat- or an-, which you say like you say _cat_ or _an_
17:20 A very odd (ironically) molecule that. Very unstable too. You would call this specifically a cycle - a cyclic chain molecule of oxygen. The previous attempt would be called a linear chain molecule (or just a linear molecule/chain v cycle/cyclic molecule). As oxygen tends to react and combine with most atoms of most elements around it, this molecule is not very likely to exist unless in very special environments with high oxygen concentration (such as pure oxygen atmosphere or in liquid oxygen, maybe).
20:30 Another quite unstable and unlikely to be found in nature molecule, trioxidane

SpaceChem was the ultimate chemistry based puzzle game
Molek-Syntez and Opus Magnum are also two very interesting Zach games, highly recommend👌
Atomix on the Amiga was good.
Thank you!
@@philippzander6494 Opus Magnum is one of the only Zachtronics games I was able to finish the _entire_ main campaign of without using a guide... Those games are crazy-go-nuts hard past the midpoint, but in a fun way!
"What do we do when chemists tell their final joke and pass on?" "We barium."
Helium is rare on earth because its so light it escapes our atmosphere when released. In our lab we use a lot of liquid helium. We have a recovery system, so we pay 25 euro per litre of liquid. If we hadn't, we would have to pay 45.
Reminds me of a more simplistic version of the game SpaceChem... which started out fun and interesting, then very quickly got to a level of mind boggling mad.
That's just Zachtronics games in a nutshell.
Which is perfect reason why Matt should play that game xd
A lot of the facts are just not quite enough information for me.. why does copper treat drinking water? I can’t tell if that’s designed to encourage you to look into it yourself but it is mildly frustrating
I might suggest this to my chemistry teacher this looks very fun to do if it’s available for free.
And here’s a fun fact that wasn’t mentioned yet:
Certain elements have to be diatomic meaning they can’t exist in nature without it being bonded to itself. The best way to learn it is with the acronym:
Br.I.N.Cl.H.O.F (Brinklehof). Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, and Flouride.
"Brinklehof" sounds like a ridiculous swear and I love it. I'm tempted to use it as another word for "buffoon" lol
*Fluorine
The -ide suffix is used when referring to ionic bonds. A common example of this with another of those elements is Sodium + Chlorine = Sodium Chloride.
As a chemistry major in college currently, I can confirm. Chemistry is confusing and hard
it was all fun and game until bio part comes in, I can't see carbon the same way ever again 💀
@@BenziLZK as someone who took interest in chemistry and biology in highschool(Finnish) the organic chemistry was quite nice and then came the aminoacids TAC AGA GAA TAG AAA TCG GGC ATC(first and last are intentional rest random)
12:05 you used the wrong formula to get the correct answer. Plus sign means it's positively charged, i.e missing an electron. And hydrogen atom without electron is just a proton.
Engineering has nothing on chemistry.
*Chemical Engineers have entered chat*
meme'd
17:11 That's a square, Matt.
I was about to bring it up !
Yes, a four sided circle is a square.
Helium-4 on earth is so rare, there was a shortage not long ago. Helium-3 is present on the moon and has a lot of potential for fusion.
I did know the part about birds and capsacin, apparently there is a species of shrew that has evolved to not be effected either.
Day 41 of notifying people that the Discord server's Suggestions forum is a better place to suggest new games to Matt. (Just don't ping him!)
When I did A-level chemistry, the first thing the teacher said was “everything we taught you about before, forget it, we lied”. Obviously it’s good to know the basic concepts but a lot of stuff you basically have to relearn
Me: **Already Knowing About The Beta Capture (Idk How it's Called in English but the thing where the Electron Falls on a Proton and they Make a Neutron and happens in Atoms with too Many Protons compared to neutrons) while the Teacher explains that Electrons orbit the Nucleus**
My Brain: Those are 3.2 Terabytes. You sure you want to delete.
Me: No.
The "bond and a half" thing you were thinking of might have been hydrogen bonds.
There is a covalent bond between the oxygen and hydrogen of the same molecule, but there are additional bonds (hydrogen bonds) between the oxygen and hydrogen atoms of separate water molecules. Hydrogen bonds are a lot weaker than covalent bonds, but they're a lot stronger than normal intermolecular forces, and they're the reason why water is a liquid at room temperature rather than a gas despite its low molecular weight.
The molecule with 2 oxygens, 1 nitrogen, and 1 hydrogen is actually called nitrous acid. Nitric acid has 3 oxygen atoms.
The positive charges on ions aren't extra protons, they're just missing electrons (often called "holes" in electronics). If an atom had extra protons, it would be a different element - e.g. oxygen with 2 extra protons would be neon.
This game reminds me a lot of THE CODEX OF ALCHEMICAL ENGINEERING, which is a cool game that I think you should play (especially since it has engineering in the name). You have to build and program a machine to manipulate the alchemical elements (how people previously understood elements before modern chemistry) and make them bond together into specific structures. It was originally built in Flash, but can still be played on a website called numuki using emulation (it used to work in Kongregate with the ruffle emulator, but doesn't seem to any more).
There is also a sequel to The Codex Of Alchemical Engineering called "Opus magnum" available on Steam.
CHEMICAL ENGINEER>CIVIL ENGINEER>ARCHITECT?
Chemical Engineer > Civil Engineer > Everyone else > Architect
FIFY
This is exactly right. Did you heard about Chemical Architects, no? Because chemistry is so hard, no architect will ever try to figure it out.
21:54 "Capskin" 😂😂
XD maybe it's a British thing?
18:40 That's also why some people will put older copper pennies (actual copper content) into their small pet water dishes, as it combats bacteria growth and stops it getting scummy as quickly
15:00 I was always taught that cations were positive since cats->pawsitive
I was taught that the t in cation looks like a plus sign and anion has the letter n which stands for negative
@@cloverisfan818 I was taught that 'cat'ions 'cat'ch the metal in electroplating.
Not only is rust responsible for Mars red hues, it was also a key player in the early earth and life's earliest days. See, the atmosphere was largely made up of inert gasses, such as diatomic nitrogen, carbon dioxide, and methane, common components of volcano outgassing. Life at the time was anaerobic, meaning it didn't use oxygen in it's metabolism in any way, but the oceans were *rich* with iron. Just floating around in the water, chillin. Suddenly these new bacteria come along and start photosynthesis proper, using sunlight to break apart CO2 molecules and turning them into sugar and O2. And boy oh boy did they pump out a LOT of O2. So much so that it started seeping into the oceans, and in turn binding with all that free floating iron. This kept the atmospheric levels of O2 at low enough levels that life was able to adapt to the oxygen entering the atmosphere, but scientists estimate it could have wiped out up to 80% of any life that existed up to that point. It's called the Great Oxidation Event, if anyone wants to look into it. It's pretty neat.
Irony when you're doing chemistry battery jokes then say you're running out...
more like "FERRO"ny
I discovered you last year and can quite honestly say that your videos help me laugh every aingle time, during quite a rough moment I am going through.
Thank you for being so genuine.
06:35 RCE nerd sniping himself with the "Hang on, I need to google this" :D
I was a Chemical Engineering student later changed to Psychology, but this part of Chemistry just tingles my mind and I miss balancing chemicals now
HAHAHAHA Laughs in SPACE-chem at this puny game
11:48 Wait until Matt learn that the same reaction (iron oxide/rust) also happens in our blood and that's why blood is red.
Poorly worded, but yes, Fe(III) compounds are red and hemoglobin is an Fe(III) compound
1:46 " Do I need to worry that their spinning" 😂they have been spinning the whole time Matt lmao
6:41 Made me think of an actual technical term in biochemistry: disulfide bridges. Sulfur loves making extra bonds, so some amino acids with sulfur in them will bond to each other inside a protein adding structural integrity to the whole protein.
Edit: 13:30 I did my undergrad in chemical engineering and biochemistry and between the two covered about 3/4ths of the chemistry degree requirements. TBH the most confusing part of chemistry is the beginning because there are tons of rules and you don't have a foundation or framework to piece everything together. Organic chemistry is fairly straightforward, there's just a ton of it. Same thing with biochemistry. Physical Chemistry is a lot of backfilling the "why" of the rules from gen chem. Quantum mechanics of bonding is admittedly a bit crazy but in an undergrad degree you don't really explore it at all.
*@Real Civil Engineer*
If you liked that game, you will love: *SpaceChem*
It is basically the same, but you can do many more things with the molecule creators.
The new "Fun Fact with Matt" is amazing. Really love it 🤯
how do you tell the difference between an engineer and an chemist? ask them to pronounce "unionised"
Organic chemisty is all molecules. All other chemisty is just cleaning glassware and pushing buttons on an instrument and waiting for the instrument to do all the work for you XD
I love doing chemistry puns but i never get a reaction 😢.
6:34 2 scientists walk into a bar, 1 ask for h2o and the other wanted some h2o too. The other died. Why?
I am stealing ALL of these jokes and tell them to my science teacher.

Yes.
Fun fact about helium: helium is rare due to two factors 1) the rapid depletion of sources by humans, and 2) due to helium being lighter than air it just keeps going once released into atmosphere until it disperses into space
It's not that it's lighter than air that's the problem - it's the fact that it's light enough that its escape velocity is a speed that it can obtain in our atmosphere - meaning that it is able to complete depart earths gravitational field, unlike other gasses, such as O2 or O3.
@UKMonkey I'm confused are you agreeing with me or not, you say it's not that it's lighter than air than proceed to say that it's so much lighter than air that it reaches escape velocity.
@@forgewolfgames Maybe what they're saying is that a gas can be lighter than air and stay in the top layers of the atmosphere, but Helium gains enough velocity on the way up that it just shoots off into space. I wouldn't know if it's possible or not but I think it is.
@@nbboxhead3866 That's how I'm reading it as well. As far as I know it's the only gas that is light enough to do that, I've seen it referred to as the only truly non-renewable resource because of it. Presumably there are quite a few gases that are lighter than air, but heavy enough that they'd rise slower than helium does and therefore never get fast enough to escape the gravity of the Earth.
@@littlebear274 Hydrogen is also light enough to, but reacts with oxygen to make water before escaping I think. All things lighter than Carbon apart from those two are metals/metaloids, and are solid at earth temperatures.
Your bond with editors is showing really well in this one, Matt.
Answering the important questions: The He we use for party balloons and other "common uses" is different to the "rare" one we need for specific lab uses (like cooling MRI machines). Different isotopes.
And helium is pretty common, its just a pain to get out of the fossil fuel gases. It originates from radioactive decay (alpha-decay).
Why is it that He4 isn't used in MRIs, if you know?
@@alext8828 because he's wrong, they use "just" ordinary liquid helium which is primarily helium 4. Helium 3 is used in much more exotic things and it is extremely expensive.
That’s completely untrue- helium in balloons and helium in MRI machines is the same thing, 4He. It’s used in balloons as it’s lighter than air, and elsewhere because it liquefies at a temperature best described as “marginally above the cold dark vacuum of interstellar space” and so keeps things like superconducting electromagnets nice and superconduct-y and electromagnet-y. It’s formed naturally from alpha decay of radioisotopes in the ground and because it’s so light it just floats off the top of Earth’s atmosphere and gets blown away by the solar wind, so using it for stupid things like balloons is a complete waste of a valuable and finite resource.
The far rarer 3He is what they’re looking for on the Moon as it’s potentially usable in fusion reactors.
@@eredaane4656 Helium is pretty common *in the universe*. Earth is much too weak to stop helium from escaping into space, so there's not much holding it here.
Be glad about that, if gravity was strong enough to keep in helium, we wouldn't be here.^
I wish i knew about this game when I took chem in high school. I bet my old high school teacher would've loved this.
"Ohh we unlocked epsilon levels!"
"I'm not actually feeling the brown, poo levels"
💀💀💀💀💀💀💀💀💀
8:16 Matt's best Star Trek joke
7:25 - It is called hydrogen peroxide because of the oxygen's oxidation number (NOX) of -1. Oxides have a NOX of -2, peroxides have a NOX of -1, and superoxides have a NOX of -1/2.
NOX is the difference between the electrical charge of an atom in its neutral state and its bonded state.
Pretty sure that the amount of dots circling it has something to do about chemistry itself, though I could be wrong.
Finally, fun chemistry.
"Engineering has nothing on Chemistry"
Me, a chemical engineer: 👁👄👁
7:52 i just begun chemistry, but i believe it is called nitrous acid
Your jokes are so insanely great, I am having a blast every single time.
The name Hydrogenperoxide comes from the charge of the Oxygen Atoms. Normally they are 2x negative charged, forming normal oxides. But when they are only 1x negative charged the form an Peroxide like Hydrogenperoxide.
Great video. Nice game. 😊 I don’t know what’s worse: Matt telling chemistry puns or no, no, that’s the worst. 😂
You can call the plus circles orbiting the atom “holes” as they are just the absence of electrons. Then you can do all kinds of hole related innuendos. 😂
This is awesome. As many have mentioned, based on another great old game
matt deserves a chemistry degree at this point
no. no he doesn't.
No, he doesn't, by faaaaaaar not
As a first sokobond game and spacechem fan this game is just perfect :>
Genius Video! Thanks a lot! 🥰🤗
17:40 Don't let your editors fool you, RCE, your humorous jokes and intriguing insights are much appreciated.
Im not sure what was worse, organic or inorganic chemistry. Learning the chemistry of medicines was a ballache
We figured this out some years ago. What we devised was: you can either be good at quant chem or orgo. There is no in-between, and PCC majors wanted nothing but pain(t) from life (and well money obviously). - Biochem students et. al. circa 2013.
My school bookstore sold bumper stickers with "Honk if you passed P-Chem" on them.
4:13 That would be formaldehyde.
7:46 is nitrous acid. Nitric acid has one extra oxygen atom.
In an alternate timeline, RCE will stand for Real Chemical Engineer
6:28 needs a bridge review 😂
1:29 there is a set amount of mass in the universe it does not increase or decrease the mass simply changes form so this would mean a lack of access to this element
Imagine you could connect them differently and it makes a different elements it'll take forever to figure out all the combinations
I can confirm that out of all my science and maths Alevels I did to get into university, chemistry was the hardest and my worst grade by a long way. First year wasn’t so bad. Second year was me sat in class thoroughly confused
6:23 RCE: "THERE'S A BRIDGE!" me: "Bridge review??"
No...
@@leearmstrong3885 no...?
Helium fits though the ozone layer and just floats off into space as far as I can remember
Honestly, the horrible puns were the best part of the video
21:03 you have summoned the whole fandom
This game reminded me of SpaceChem! What a game that one is
Also the bond between H and O is strong as the oxygen is highly electronegative, attracting the electrons more, so the O becomes slightly -, the H becomes slightly +
I've made all those jokes and then some back in highschool chem, I was really in my element. Though I made sure to only make those jokes periodically. At least I got a reaction from those jokes, my others were inert. That or my other classes were full of nobles...

15:14 cat-ion and on-ion
Like battery chemistry.
If I had this game in college, maybe I wouldn't have failed organic chemistry. 😅
I'm a bit surprised there was no bridge review.
Two chemists go into a bar. The first says: "I want H2O." He gets his drink. The second chemist says: "I want H2O, too." He gets his drink and dies.
My chemistry professor had us remember that CAT-ions are PAWS-itive.
Dad jokes are running wild here 🤣
Helium is rare. That's why most places have stopped filling balloons with it. Helium is rare because it literally just escapes the atmosphere and cannot be recovered. All the helium on Earth is created through radioactive decay. There was a crisis a few years ago as the helium reserves were running out, but we've since found new radioactive sources so it's not as critical as it once was. However, as a result helium isn't so cheap anymore so you see less and less balloons filled with them. You can still get them, but you're paying for it.
Endangered means it’s on the edge of extinction and extinction means completely gone which means there’s no more of that certain animal
specific type of helium on the moon Helium 3. not the type used in balloons.
"What is four oxygens stuck together?"
tetraoxygen
The + near "atoms" (they're actually called ions now) still means the atom has lost an electron, not gain a proton. If it gained a proton, then that would make another element.
