What is the most useful compound of hydrogen?
water
Is hydrogen peroxide good for cuts?
Depending on the severity and cause of the cut, hydrogen peroxide may or may not be useful. It is highly recommended not to use hydrogen peroxide on deep wounds. For small wounds with debris, hydrogen peroxide is useful to dislodge small particles within the wound. In this case, it is recommended to rinse the wound with clean, running water as well.
What do experts say about hydrogen use?
it's abundant and useful. It uses a lot of energy.
What is a challenge to using hydrogen as a fuel because hydrogen powered cars create less pollution than gasoline powered cars?
New fueling stations that can handle hydrogen would have to be built.
Is hydrogen useful to fly?
Yes, hydrogen is useful for flying because it is a lightweight and efficient fuel source that can power aircraft, such as hydrogen-powered airplanes or airships. It is also renewable and produces zero emissions when used as a fuel, making it a more environmentally friendly option for air travel.
How acid are useful for kids?
amino acids are molecules made out of hydrogen,oxygen,carbon and nitrogen atoms (and a little sulphur).
How do you calculate the second wavelength in the Paschen series?
Use the Rydberg formula. A useful article about this is on Wikipedia. It is called "Hydrogen spectral series".
What properties make helium useful?
While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.
Why is a fuel cell useful in spacecraft?
because hydrogen is in the fuel cell. hydrogen is useful in many things including spacecrafts. please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true.

Why is hydrogen emission useful in mapping the arms of the milky way?
Because hydrogen is the most common element in the universe and also it has a spectral emission line in the microwave radio part of the spectrum making it easier to track with a radio telescope.
What is hydrogen shine?
The hydrogen line or "shine" is the frequency (1420.40575177 MHz) or wavelength (21.10611405413 cm) of electromagnetic energy emitted by an excited hydrogen atom. This is not a "shine" in the sense of visible - it is in the microwave frequency range. It is useful in radio astronomy because it passes through dust clouds that block visible light.
