So many people missing the point with this. It's clearly a visual representation which has been made so more people can have a better understanding of how this complex process works. Thank you for posting this.
Exactly! Videos like these are really valuable, entire movie budgets should be rerouted to make content like this, and then they should be incorporated into great works similar to Carl Sagans: A Personal Voyage.
@@geirtwo I agree completely with this comment and it is something I've often thought about myself as a teacher and RU-vid creator! My guess is that creating content such as this for general chemistry would cost much less than the budget of a small movie, especially since distribution could take place on existing platforms. An if it was released under a Creative Commons license it would really have legs.
It’s like those pro intelligent design you tube pages that stole the molecular machines animations and are claiming them as proof not realizing how stupid they look since that’s not how it really works its like this a model that lets us better visualize what’s going on but it by no means it’s an exact replication
This is how most people should respond, but, on the contrary, they seem to just want to nitpick at the fact that the simulation was not a video of an actual microscope working at an atomic scale, if that is even physically possible.
Loved it. I think some get in trouble misinterpreting the wording (while looking for something to nitpik). I just have one thing to say, "great simulation, very informative and eye-opening."
@@dime3868 you create with a energy source.. fire from lighter for example ! From there a chain reaction occur until all hidrogen is "burn"/re-arrange at molecular state in his equilibrum state . I watch this video and suddenly I'm so smart that I can even offer explanations !! :))
One of the few times I can easily forgive the quasi-clickbait title. This is an excellent visual presentation of a process that goes on all the time, and yet so few understand. Let's face reality, all you downthumbers: would you have clicked on this lucid and top-notch vid if it had had an unexciting title? The fact that you, and I, clicked is proof to the contrary. Otherwise, though, I share your Sith-like hatred for clickbait that doesn't provide equal or greater value of that expected. Which is well over 95% of them. I'd say however that this one is in the "provides greater value than expected" category. As much as I like to see what we've imaged in the micro and macro world, it is even rarer to see a presentation like this that presents a chemistry topic in such an easy to grasp manner. Cheers.
Just in case anyone is wondering why the intitial reaction doesn't create H2O, I believe its because the hydrogen atoms are not at the right angle to create water and bond to the oxygen. Angular approach is just as important as having the right ingredients
@@classica1fungus yes as a minor by-product. fire can be described as the rapid decomposition of an organic substrate on earth conditions in atmosphere. The molecular carbohydrates are quickly recombining into enthalpicly simple structures while releasing heat, thus contributing to additional degradation. Some water will naturally be made from this.
I would hope pretty much anyone would know that a hundred-million x microscope can only be hyperbole, a story telling device. To say that it is a deliberate deception is being overly literal.
Awesome video. I teach college biochemistry and work in a molecular graphics laboratory, and I learned stuff - so that's a thumbs up from me. I do agree that the title is misleading - perhaps it should be called a "virtual microscope". And is it a computed quantum mechanics simulation? I discussed it with our QM expert here, Diogo Santos-Martins, and he thinks it might be, or at least is based on one. The movements of the particles looks realistic, at least, but it's a bit suspicious that they stay so planar. I wish there were a better explanation in the caption. Also, they said that the actual reaction was a bit more complicated - I'd like to see more about that. All in all, though, a great effort. I'd love to see more videos like this.
Every other science video: "don't try this at home" MEL Science: "You can try making Hydrogen at home" *shows pictures of it exploding and catching fire*
This is great, thank you. I do think you need to add more information within the video to explain the dangers. Kids: Don't try this at home. This experiment can easily kill or disfigure someone.
B. M. : every person would a brain would check his or her comment for errors before posting. especially if intelligence is mentioned. just sayin'... :-)
Excusing the artists licence 100,000,000 X microscope, this was very good. If only science had been taught like this when I was at school! I've never done the hydrogen experiment, so that's on my to do list now! I don't think we have drain cleaner like that in the UK though!
You forgot one very important ingredient - activation energy! H2 and O2 can 'hangout' together, like friends, forever, without anything happening. Energy must be added to start ionization, then kaboom! Fire! H2 becomes oxidized, still ionized into H+ and OH- After energy is removed (cooled) they come together as H2O.
Anyone who is complaining that this is not a microscope is ignorant. The video clearly says SIMULATION of Hydrogen burning under a 100 million x microscope. Atoms combine and vibrate so quickly that I highly doubt the possibility of filming atoms bonding with the technology we have right now. Anyway nice animation.
This video states when oxygen atom meets H2 molecule, it doesn't produce H2O immediately, instead it creates H and HO. HOWEVER, it does not explain WHY!
Oxygen molecule is usually in "triple state" and does not react. We dont usually have spontaneous combustion. It needs extra energy, that make oxygen molecule to move to so called single state..true? This combination of cancellations and σ and π overlaps results in dioxygen's double-bond character and reactivity, and a triplet electronic ground state. An electron configuration with two unpaired electrons, as is found in dioxygen orbitals (see the filled π* orbitals in the diagram) that are of equal energy-i.e., degenerate-is a configuration termed a spin triplet state. Hence, the ground state of the O 2 molecule is referred to as triplet oxygen.[30][b] The highest-energy, partially filled orbitals are antibonding, and so their filling weakens the bond order from three to two. Because of its unpaired electrons, triplet oxygen reacts only slowly with most organic molecules, which have paired electron spins; this prevents spontaneous combustion.[31] (from wikipedia article oxygen)
Cause before he made this video, nobody knew, that hydrogen was explosive... I'd also like to see a concept for a bomb using hydrogen (not as a nuclear fuel for fusion, but as a chemical one).
Dozens of people ( myself included ) complaining about the title. The title SHOULD be "CGI illustration of Hydrogen Burning" . MEL Science doesn't care, just adds more clicks to their ego.
Do you want to say radical water is the final product from this animation? How did you get 100 m magnification for your microscope? yet, why do we see a dark background between gas molecules? another point: why do we see foam growth covering the top of the funnel while getting the spark closer to flame hydrogen gas? after the explosion, did we see the foam sparkling or a real H2O liquid? I doubt that you have made the latter! the ones performed similar experiments using two dry bottles for O2 and H2 for example, did not show water vapor before and after the explosion? however, they added vapor to one of the bottle walls before the explosion when video got replayed at slow motion! that's scam!
Bro i was just studying thermodynamics and saw this reaction, I was so curious about it and boom, this vid shows up in my recc, thank you for making this video
Good simulation, but there should be mention of valence shell and electronegativity. Also, not your fault, many commenters should go back to watching sports on the Telly. Your title is quite clear that this is a simulation of what you would see if you could use a microscope to see the reaction.
If heat is a cinetic energy ant if it's not regularly distributed in atoms so somes molecules are faster than others and at a a given temperature we can draw a Gauss curve with the energy of molecules in the x axis and the number of molecules in the y axis and a vertical line that tell us the dissotiation energy of the molecule. So the molecules at the right of the line are radicals?
They changed the title from "Hydrogen burning under 100,000,000x microscope (2H2+O2=2H2O)" to "Simulation of Hydrogen burning under 100,000,000x microscope (2H2+O2=2H2O)" Because a microscope was not involved and the physics of each interaction appear simplified, a better title could be "Steps of Hydrogen Combustion at 100,000,000x Scale (2H2+O2=2H2O)"
The things you can find on youtube these days.. Makes me wanna say 'back in my day, we didn't have all these fancy educational videos, only boring old textbooks!'
So many blind people haven't even read the full title yet. It says SIMULATION right in the title. Very surprised people haven't realized the need glasses yet.
It says simulation in the title, of course it's not a 100 million mag. You could only get that kind of resolution in a TEM, and I really am not sure how you would watch a gas burning, let alone at these slow speeds.
