How long does it take the Sun to convert one Jupiter mass of hydrogen to helium?

∙ 13y ago
Jupiter has a mass of 1.8986×1027 kg or 2.09284825 × 1024 tons
Depending on the sources [See related question], the Sun converts about 600 million tons of hydrogen into helium every second.
So a/b gives 3,488,080,416,666,667 seconds.
Or 110,532,959 years

How long can a human stay on Neptune?
Not very long. Neptune is made of Hydrogen and helium. So you can't breath.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
Explain why helium is a safer choice than hydrogen for filling large balloons.?
Almost any gas will work, as long as it doesn't react with the balloon material. Air is the cheapest, Hydrogen is the lightest if you want it to float, but since the Hindenberg disaster it is considered a dangerous substance so we usually use Helium. Other gases have different physical characteristics, like some are fairly heavy compared to the air around us. Some change the rubber or mylar or whatever the balloon is made of into something unexpected. Fun with chemistry!
How many electrons do hydrogen and helium need to fill their outermost energy level?
Helium already has a full valence shell. Because the first orbital holds two, and the second orbital holds eight...Helium is already filling the first shell with its two electrons, and it has no more electrons to spill into the second orbital, therefore it's one and only shell is full. Hydrogen tends to gain one electron in order to fill its outermost energy level. Hydrogen only has one, but it needs two to fill it's valence shell, so it will gain one. Long story short, helium is already full (that's why it's in the noble gas group) and hydrogen tends to gain one electron, and form a negative ion. No honey it has a number and that is 2 duh!!
Explain why helium-filled Mylar-foil balloons can float freely for several weeks but latex balloons for less than 24-hours?
Helium is not only very light, it is also monatomic, it's particles are all made up of a single atom. Air molecules, oxygen, and nitrogen mainly are larger and hevier and diffuse through much more slowly.

What are the two main gases that stars are made of?
Our star I can tell you more about, but Alas Until we can burn ourselves up in other stars (which are at least light years away at the closest) I can only tell you the Chemicals the sun uses. The sun is about 75% Hydrogen, and just about the rest is mostly Helium. Which there are so plentiful amounts that It can burn for a very long time, at least until there is no more fuel. O.o
Why is the presence of large amounts of helium in the spectrum of a star generally considered a sign of age?
Stars begintheir lives burning hydrogen and converting it to helium. If there are large amounts of helium in a stellar spectrum, it would indicate that the star has been making helium for a long time - hence age.

What keeps the sun on fire?
The sun produce energy when it converts hydrogen atoms into helium atoms in the core of the sun. This process will go on for as long as there is enough hydrogen to convert. In some larger stars, the process can also stop if the pressure of the converted atoms become too high. In this case, the sun may explode from the pressure itself into a super nova.
Why is getting hold of hydrogen so hard?
It isn't hard to get hold of Hydrogen. Simply put a current of electricity through water and you will split the two hydrogen atoms from the oxygen atom. I think you may be mistaking Hydrogen for Helium. Helium cannot be manufactured its a by-product of natural gas that has been distilled in radioactive decay for a very long time and you cant take one element and turn it into another.
What country is helium from?
The USA produces about 80% of the world's Helium . It is the second most abundant element in the Universe. When the singularity that preceded the universe erupted in what we call 'The Big Bang', hydrogen particles began to form, and from these helium resulted in the nuclear furnaces of the early stars. Most of Earth's Helium is the result of radioactive decay, originating in the long run from the core of the Earth. There is a good article on Helium in wikipedia.
Are Jupiter's days fast or long?
Quite fast, a day on Jupiter is 9.925 hours long.
Can air be changed?
air can be changed if their is enough gas to change it also the air a long time ago was mainly hydrogen and helium now it is mainly oxygen, carbon dioxid nitrogen
How long will it take for 2G of tritium to decay into 2Mg?
Tritium is an isotope of Hydrogen. It has one proton and two neutrons. It decays into Helium or He. It takes 12 1/2 years for half of the original amount to decay into helium. It does not decay into magnesium. So the answer to your original question is forever.
Why is a day on Jupiter about 10 hours long?
A day on Jupiter is about 10 hours long because Jupiter spins very quickly on it's axis.
