What else can I help you with?
I know that the Sun burns hydrogen to create helium but what is the Sun doing with all of this helium What would happen if the sun had no helium And what role does helium play in making the sun hot?
The Sun uses the energy produced from converting hydrogen into helium through nuclear fusion to generate heat and light. If the Sun had no helium, it wouldn't be able to sustain this fusion process, leading to a lack of energy production and a collapse in the Sun's structure. Helium plays a crucial role in the fusion reactions that occur in the Sun, contributing to the high temperatures and pressures required to sustain nuclear fusion.
What substances make up most of the solar system?
That would be the hydrogen in the sun. The second most plentiful substancein the solar system would be the helium in the sun, being the fused hydrogen.
Why is the presence of large amount of helium in the spectrum of a star considered to be a sign of age?
Stars fuse hydrogen into helium, and then fuse the helium into carbon. For a star to have more than about 50% helium, we know that the star has already burned up half of its natural fuel, and that the end is near.
Why would an older main sequence star composed of a higher percentage of helium than a young main-sequence star?
Im no astrophysicist but an older star would consume more of its hydrogen over time in comparison to helium through its fusion process. Over time concetrations would change resulting in a higher helium to hydrogen ratio.
What is a medium size yellow star composed mostly of hydrogen and helium?
All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.
Would an hydrogen balloon float better than a helium one?
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Where would Helium 1s be relative the hydrogen 1s?
There is one thing that is relative to both helium and hydrogen. Both of these are a type of chemical.
Is helium safe to fill balloons with?
Yes. I would go with helium if you can get it. Hydrogen can explode.
Is the sun made up of mostly hydrogen?
Essentially yes; the sun's energy comes from nuclear fusion with hydrogen being converted to helium.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Which gas would be more suitable for the Hindenburg?
Helium was more suitable but not available in Germany before the war.
How is the formula for hydrogen different from the formula for helium?
I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if; Hydrogen gas: H2 H-H Helium gas: He Hope this helps
Why does a helium balloon lower after a while?
That would happen after it loses a certain amount of helium.
Would a helium balloon float on a planet made of hydrogen?
No, because the density oh helium is bigger (x 10).
What state would hydrogen and helium be at room temperature?
They are gases at room temperature.
What gas law explains the replacement of hydrogen to helium in blimps?
The replacement of hydrogen in blimps with helium is not based on the gas laws but rather on the fact that hydrogen is highly flammable whereas helium is entirely non flammable. In fact based on the gas laws hydrogen would actually be better for blimps because its has lower molecular mass and is therefore less dense than helium.
What happens when the hydrogen nucleus hits the helium nucleus?
I'm guessing here, but I think you are asking about nuclear fusion. in that case, what happens when a hydrogen atom hits a helium atom? Not much. Fusion would require two hydrogen atoms. What would happen when two hydrogen nuclei hit together? If the pressure and temperature were high enough, the two hydrogen nuclei would fuse, creating an atom of helium, along with a high explosive force and an extremely high release of heat.
