Combustion of hydrogen and oxygen in your hands 

if she try it right in their hands is obvious not more dangerous than normal fuels which are way more energy dense with respect to volume.

AngelLestat2 No. not true. The only reason it’s not dangerous is because the reaction happens so fast the energy doesn’t have time to spread to the woman’s hands. The energy is mostly absorbed by the air around it.

Emil Georgiev 1. Faster than the speed of sound 2. Heat, sound and light energy

Actually we do. Its just not practical.

@@mohammeduzairkhan4951 I guess I should've ask, will it have spark plugs or some other mechanism for ignition? Either way, I think it's an awesome concept.

that's not true!

They don't in our opinion, there's no proof water is hydrogen and oxygen, only lousy demos like these that show nothing. We think the reaction seen in the video is a release of 'hydrogen pressure' enhanced by the oxygen. The flames are only brought about due to the flammable impurities contained in the 'hydrogen pressure' from the way it was manufactured.

Anyways, Water is of course H2O. Two parts hydrogen and one part oxygen for each molecule. In this reaction, you are taking H2 gas, and O2 gas, and burning them. Burning these two is a combustion reaction with the formula of 2 H2 + 1 O2 -> 2 H2O. When you burn something, it creates a small plasma (fire) where the molecules of H2 and O2 break apart into separate atoms. Hydrogen (H) wants to get rid of it’s one electron to become stable. Oxygen has 6 electrons in it’s valence shell, but it wants 2 more to get a full valence shell (8 electrons) to become stable. Since Hydrogen wants to get rid of it’s electron and Oxygen wants 2 electrons, 2 Hydrogen atoms will bond with the Oxygen atom to form H2O. They form a polar covalent bond where electrons are shared, but since Oxygen is a bigger atom, it pulls them closer to it, giving slight positive and negative sides. This leads into intermolecular forces and Hydrogen binds but I won’t talk about that right now. It is also possible to reverse this whole process kinda through electrolysis. Electrolysis is where you run an electric current through water wither two sides, an anode (positive side) and cathode (negative side). The electric current essentially transfers lots of energy to the water, which is able to split the bonds between the Hydrogen and Oxygen. The atoms of Hydrogen are pulled to the cathode (negative side) due to their positive charge as an ion, and well, opposite charges attract. The Oxygen is pulled to the positive side (anode) due to it’s negative charge. The Hydrogen atoms then bond with others to become H2, where it then bubbles up to the surface of the water. The Oxygen does the same. A simple way to do this is to get a cup of water, put some baking soda in as a catalyst (to get better conductivity) dissolve it, and put a 9 volt battery (the ones with both ends on the top so you can link them in series) in the solution. You will notice the small bubbles coming off of the negative side, and very slightly bigger ones off of the positive side. This is Hydrogen and Oxygen Gas. You may notice the positive side will corrode and rust pretty fast, this is due to the Oxygen making Iron Oxide (rust) and since it is pretty pure Oxygen, it happens pretty fast. If you put a flame to where the gas is coming off, you’ll notice an orange outer flame from the H2 and O2 burning, going back to where this whole thing started. Welcome to Chemistry!

@@silverowl6702 But none of what you type proves water is made of hydrogen and oxygen because other conclusions can be drawn from those observations! Welcome to your opinion!!

Peter & Pete I just provided the explanation, and a way to prove it. I did forget to mention why to put baking soda though. If you use salt instead you’ll get Chlorine gas off of the anode instead of oxygen, which is toxic to humans. If you do both ways you’ll notice the one with baking soda burns better due to the oxygen. If you light a flame where the gases come off in the salt one you’ll get some hydrogen burning relatively quickly in a little puff. If you repeat this with the baking soda instead you’ll get a quicker and louder puff due to the influx of oxygen.

@@silverowl6702 you don't get it! Let's try another tactic - how can you demonstrate oxygen originates from water alone via the process of electrolysis! You say it comes from water whereas I say oxygen comes from either certain electrolytes added to the water or from the breakdown of the electrode (anode) There you go, I have provided an alternative theory as to what happens during the process of electrolysis and oxygen generation. How you going to disprove that?

2H2+O2----->2H2O

Heat 2h2+o2--->heat+2h20 To have a combustion oxygen must be present. Hydrogen and oxygen air that is then lot will produce a flame and water

only the most abundant element in the universe (water is mostly hydrogen)

Helium*, but yes.

90% of all atoms in the universe are hydrogen.
