Hey. Can anyone explain how the hydrogen carbonate ion is formed? Seeing as its structure is that of a molecule, I’m assuming that a molecule gained an electron from somewhere to form a negatively charged ion? Please help! I just really need to know how the ion is created.

Recently, I applied some hydrogen peroxide to a bed sheet, and now it is on my finger tips. I can’t get it out by picking because there is too much, and I don’t know how else to remove it.
Thanks

Is it mostly the hydrogen peroxide cream doing the lightening? Or mostly the lightening powder? Or both at once? What would either do by itself? Just curious. Thanks if anyone knows.

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.

I need to knwo if hydrogen chlodie, hydrogen bromide and hydrogen iodided are readily soluble in water (and is ther a residue of undissolved gasses left-what?)
The reaction of the gases with amonia ad what they form.
The stability of the gases towards heat.

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.

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

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.

It is widely believed that an atmospheric increase in the greenhouse gases CO2 has played a significant role in global warming. Even now, CO2 accounts for less than 1/3 of greenhouse gases. Water vapor, on the other hand, accounts for approximately 70% of all greenhouse gases.
The byproduct of hydrogen fuel cells is water vapor. Let’s pretend that every vehicle in America is powered by hydrogen say 10 years from now. That’s a lot of water vapor! What effect would it have?
