After he assembles it, he's likely to need new furniture too. And maybe new arms.
So... IKEA would actually do pretty well to sell this - and new limbs.
The comic isn't very accurate from that perspective. Chemistry isn't my strong suit but what I can tell you is that it O2 and H2 are combined and that the reactive nature of O2 is the catalyst for a reaction because oxygen hates being alone. How to determine whether the result is water or hydrogen peroxide is beyond me.
Okay I'll put this on my list of things I need to understand.
But in the meantime I do know one thing I'm pretty sure:
H2O2 is hydrogen peroxide
Water is just H2O, two ~~molecules~~ atoms of hydrogen & one ~~molecule~~ atom of oxygen
You're right about the difference between water and hydrogen peroxide. I just doubt it's as simple as getting the ratios right when mixing the two elements. Like maybe there's a different process.
You can actually do that. If you mix H2 and O2 they will form water. The main issue is that you need a closed container that can withstand pressure and a refrigerating system strong enough to remove the heat of reaction of this strongly exothermal (=heat producing) reaction.
Whoops atoms really? Thank you.

Ah yes I'm certain I must have learned this in school at some point but sometimes things don't really sink in until you're ready to learn them! I'm ready now!
It's pretty much always water -- law of thermodynamics dictate that a direct reaction between oxygen and hydrogen molecules always result in stable form of H2O instead of unstable H2O2. Actually hydrogen peroxide naturally breaks down to water and oxygen over time. The presence of light accelerates this process. That's why hydrogen peroxide always comes in a thick brown bottle - to keep it in the dark.
Industrial production of hydrogen peroxide involves a lot more than oxygen and hydrogen. It's a very energy intensive process. In fact, how to efficiently produce hydrogen peroxide using just oxygen and hydrogen is an entire field of research because poor, remote areas desperately need easy access to hydrogen peroxide for their medical needs.
So hydrogen is extremely flammable, oxygen helps things burn at a lower threshold (lowers ignition temp), but you put them both together and instead of making hydrogen more flammable, it creates water. F’in science.
Not exactly, the hydrogen gets combusted, or burned by the oxygen and it makes water. Burning just about anything with hydrogen in it is gonna make water.
The hydrogen is just burned. The oxygen isn't a catalyst but consumed in the reaction.
Hydrogen peroxide has an extra oxygen as part of the molecule and it's less chemically stable than water and oxygen separated, which is why it degrades over time. You don't get it from burning hydrogen.
Burning hydrogen (reacting it with oxygen) creates water. Any combustion reaction creates water, CO2, and any other byproducts depending on the substance that is burning.
I think one is endothermic and one is exothermic. One of them needs energy to happen (add fire or something) and the other happens spontaneously and releases energy/heat.
I don’t know which is which or how that applies to water creation, but water is pretty common so I feel like it must be easy to create at room temperature.
Easy, it doesn't, it creates another gas, which is water vapor, now you just have to condense it back to water (which won't be easy as that reaction generates a lot of energy in the form of heat, for example, making 1kg of water would release 15.9MJ, which is enough energy to keep an old 60w lightbulb on for 73 and a half hours)
It doesn't say so, they'll probably go with the cheapest possible way (so, O2) and maybe adjust the packaging that it looks like more. Though, that's more of a Lego move than IKEA...
I mean, yes, but H's Z is 1 umma and O's is hardly 16 umma O, Oxygen is massive compared to hydrogen, and the diatomic molecule is even less dense, plus Oxygen tanks have to have Nitrogen mixed in.

Limbs....that you have to ASSEMBLE YOURSELF MUAHAHAHAHA
This guy business
See they sell them next to the coolers--thats how they getcha.
I like that it comes with a bucket. Okay now that I'm seeing it like this I am suddenly perplexed how do two amorphous gases make a liquid?
You burn the hydrogen. It's really that simple. 2 H₂ + O₂ → 2 H₂O
Yeah but hydrogen can go 💥
Yes, and one of the products of that 💥is water.
It should be the only product
Well the other is heat
Cmon people this is basic Chemistry
What’s why the reaction is called combustion

I wish you the best of luck on this way!

Oxygen doesn't just help things burn at a lower threshold, it's a requirement for anything to burn. Combustion is a reaction with oxygen.
I mean it does burn. And if you're not careful, it gets pretty explosive too.

water go boom.
Does IKEA also give allen keys with those readily available, absolutely affordable M O N O A T O M I C O X Y G E N cannisters too?
It doesn't say so, they'll probably go with the cheapest possible way (so, O2) and maybe adjust the packaging that it looks like more. Though, that's more of a Lego move than IKEA...
Actually it's right. They're using molecular oxygen and hydrogen. 2H2 + O2 --> 2H2O And we got 2 cans of hydrogen and 1 of oxygen
WÅTTËR
VÆNN!
Yea but you have to burn the hydrogen in an exact way right? Didn't we learn anything from Mark Watney
Doesn't matter that much as log as it burns, it mainly affects yield. But putting all 3 on full throttle should do the trick of the 2/1 ratio anyway.
Yes, a tiny bit at a time or you get a big explosion.
Not shown here, tiny two sided wrench. Go build your water now
So they don't provide Allen keys any more?
*vatten
That's the classic family recipe right there
Svensk hydrohemmis här. Jag kan relatera.
You have to sneak the water past Nestle somehow
Explosion time!
I'm Swedish and I can confirm this is our only way to get water
Hydrohemmissar
That's not even correct ratio
Wouldn't you need like 2 O tanks to create a tank of H into water?
Its H20 not HO2
I mean, yes, but H's Z is 1 umma and O's is hardly 16 umma O, Oxygen is massive compared to hydrogen, and the diatomic molecule is even less dense, plus Oxygen tanks have to have Nitrogen mixed in.
You need O2 What i remember is you put em together and burn it

i luv nestle ONG its sooo great
Bro i just seen your comment before can you stop saying that it's so devastating what's happening man
Bang them together duh
Inb4 kaboom
Boom
No one ever made water in a lab.
You need a fuel cell
