Can the Hydrogen created while charging a lead acid battery be fed to a combustion engine?
Q. In a Diesel engine LPG is added to boost performance. Could Hydrogen go the same, without expensive equipment? A Hybrid with lead acid batteries would produce more Hydrogen, maybe enough to make a difference.

A. Any well-managed battery system will regulate the charging process to avoid generating hydrogen, because this wastes energy and depletes the electrolyte. Given that electric motors are far more efficient than combustion engines, it makes no sense to use electricity to generate hydrogen for fuel in a hybrid system. In any case, the amount of hydrogen produced, even with overcharging, would be too small to be worth building a system to capture and burn.

What percentage of hydrogen peroxide should I use to get black stains off of laminate flooring?
Q. The floor has black patches from cat urine. I know hydrogen peroxide helps in removing most of the black. But what % would be most effective? Anyone who has had this problem and has got rid of atleast most of the black marks using hydrogen peroxide, I would really appreciate your help! Thanks guys :-) Londonsyard

A. The shiny coating of the laminate is beautiful, but, liquids can seep and soak under that coating causing stains to be very hard to remove. I've already used NON acetone nail polish remover to work on permanent marker on laminate flooring. I also had a bucket of water with dish soap ready to wipe up the remover. You may even try a Magic Eraser in a very small area of the stain and see if that wouldn't get it up easier. I'd use the peroxide full strength also. Just have a wet rag ready to wipe it up with.

What is it about the hydrogen atom that allowed it to produce photons of this type?
Q. It was determined that not all of the lines in the hydrogen spectrum were visible. There were some discovered in the ultraviolet range A. Hydrogen has an invisible area from which photons outside the visible range originate. B. Only the hydrogen atoms from the sun emit ultraviolet rays. C. Ultraviolet photons have a longer wavelength, thus more energy. D. Higher energy photons come from transitions between energy levels of greater difference in energy. E. This is known as the ultraviolet catastrophe and never really took place.

What is the strongest evident for hydrogen bonding?
Q. 1. Hydrogen has an extremely low electronegativity. 2. Hydrogen is able to accept or donate electrons, so it is the most versatile atom in the periodic table. 3. Hydrogen can be considered either a metal of nonmetal. 4. The boiling points of NH3, H20, and HF are abnormally high compared with the rest of the hyrides in their respective periods.

A. Ok... this may or may not work, but here's my shot at it. 1.) Cool the bottles of hydrogen and oxygen as cold as you can possibly get them. Gasses take up less volume under low temperatures. 2.) Hydrogen transfer is easy - it's lighter than air, so open the bottle upside-down, put your receptacle against the opening, then flip. The hydrogen will displace the air in the bottle. Oxygen transfer is somewhat more difficult. You may want to start with oxygen - a plastic syringe may be sloppy, but effective.

Is it possible to build my own hydrogen-powered car and produce my own hydrogen to power it?

The way to make it in large quantities is to electrically produce it from water. That requires a lot of electricity. That electricity has to come from somewhere. The energy companies will provide that electricity. To deal with the increased demand they will probably have to burn more fuels. They might make more money.

And if you go all the way through you end up with no water and only hydrogen and oxygen. Although its theoretically not possible as pure water isn't conducting so acid has to be added to serve as an electrolyte.

When you first light the H2, it burns above the can - in O2. As the pressure of H2 in the can decreases, O2 from the air enters thru the other hole. When there is sufficient O2 inside the can = boom!

What happened to a balloon that is inflated with hydrogen gas, but in a few hours the baloon was deflated?
Q. A rubber balloon was inflated with hydrogen gas. In a few hours, the balloon was observed to be practically deflated. What has happened? Remember the pressure inside the balloon is equal to the atmospheric pressure. I think it is that hydrogen is lighter than the air outside the balloon which causes the hydrogen to become diffused out of the balloon more quickly. Is that even remotely correct?

After I installed the two hydrogen units I now get 28 MPG on the freeway. I plan to connect another battery in the back of my truck and add 8 more hydrogen units making a total of 10. I hoping to add that many based on how many amps the battery can produce or handle. If I got 10 MPG on 2 units, what will 10 give me? Free fuel!!! Truck runs so much smoother and has tons of power! I got my neighbors doing the same things to their cars. I plan to add a hydrogen unit to my 2007 Rav4 as well. Good luck!

How easy is it to make hydrogen at home?
Q. I would love to buy one of those hydrogen powered ENV bikes, but the problem is where do I get the hydrogen from. One option is to make it myself, but I wonder how easy or practical this is, and what are the costs. Thanks for the answers so far... I know that in principal making hydorgen is easy -- I did that in my highschool science class. What I want to know is: How easy and practical is it to make enough hydrogen to power a vehicle to go to work every day? Consider that to be practical, a system would need to be able to collect and store presurized hydrogen so that I can fill my vehicle's tank with it.

A. Add a little salt or acid to water, run a DC current through the water and you get Hydrogen and Oxygen being made at the electrodes. If you keep it away from oxygen, hydrigen is not explosive. Both gases can be stored in heavy glass containers. I don't think you can make enough to run a hydrogen powered vehicle. Voice of Insanity: fuel cells make water and electricity from hydrogen and oxygen! They don't make hydrogen!

What would happen if I used 4 year expired hydrogen peroxide?
Q. I'm taking care of my nephew and he spilled some of his grape juice on his shirt Is it ok if i used expired hydrogen peroxide? It's 12-30-08, and the expiration date on the hydrogen peroxide is 09-05 Would anything happen to the clothes? I was planning to put his shirt in a container and let it soak in hydrogen peroxide and water overnight. then normally wash it in the washing machine This usually always works, but the HP has been expired for 4 years now! What do you think?

A. It isn't likely to bubble as much Hydrogen Peroxide is H2O2... there's an extra oxygen attached to a water molecule. It's that extra oxygen that causes the bubbling action. It isn't very stable and the oxygen atom likes to jump off, making gaseous oxygen and plain water. The hydrogen peroxide you get in the store isn't pure H2O2, it usually has some water in it... old hydrogen peroxide will just be less strong than new hydrogen peroxide.

How to find the ionization energy for a single atom of hydrogen?
Q. I don't know how to find the ionization energy for a single atom of hydrogen. I know that the ionization energy for hydrogen is 1.31 X10^6 J/mol, but how can I find the ionization energy for a single atom?
Asked by el camino - Mon Oct 19 13:09:35 2009 - - 1 Answers - 0 Comments
A. Since you have the ionization energy for 1 mole of hydrogen atoms, just divide that by Avogadro's number to get energy/atom: 1.31 X 10^6 J/mol / 6.02 X 10^23 atoms/mol = 2.18 X 10^-18 J/atom

How can you tell if a molecule has a covalent or a hydrogen bond?
Q. So hydrogen bond is usually between H and strong electronegative atom such as O, N, F. When you have something like NH3 or OH how do you know if they are covalently bonded or have hydrogen bonds? Can you give an example of a hydrogen that is covalently bonded and hydrogen bonded?
Asked by rdmqtn - Fri Mar 20 15:26:20 2009 - - 3 Answers - 0 Comments
A. Hydrogen bonding refers to attractions between the hydrogen in one molecule and the anion in another molecule, such as the hydrogen bonding between molecules of water. It's not a chemical bond within a molecule. Covalent bonding occurs within the molecule when the two (or more) bonded atoms share the electrons between them. Again, water is an example of covalent bonding.
