How many moles of hydrogen gas contian the same numbers of atoms as there are in 16g of helium?
The atomic mass of helium is 4, so there are 4 moles of helium in 16g. Since we want the same number of atoms, we want 4 moles of H, which is 2 moles of H2. (If you really meant same number of molecules of hydrogen as there are atoms of helium, the answer is 4 instead.)
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?
the number of helium and hydrogen atoms is the same
Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.
Hydrogen atoms fuse into helium.
None. Hydrogen and Helium are elements. Helium gas is made of atoms of He, there is no Hydrogen in it at all.
Hydrogen and helium make about 98% of the atoms in the solar system !
Hydrogen atoms undergo nuclear fusion reaction to form helium.
two hydrogen atoms
For the creation of Helium, two Deuterium(an isotope of Hydrogen) atoms combine instead of the normal hydrogen atoms.
The sun consists of hydrogen and helium atoms. The hydrogen atoms combine in a process called nuclear fusion, releasing energy and creating helium atoms.
All of the atoms except for hydrogen and some of the helium were made in the cores of stars. All of the hydrogen and many of the helium atoms were formed during the Big Bang.
Nuclear fusion of hydrogen isotopes to form helium
Helium originated from suns, where the fusion of hydrogen atoms forms the helium.
The gas formed when hydrogen atoms fuse is helium. Stars do this.
No. Hydrogen atoms combine to form helium.
i dont know blaa
Hydrogen and helium are the two lightest atoms
they compose by there atoms
The sun and other stars are composed primarily of hydrogen and helium. The hydrogen atoms combine by nuclear fusion resulting in helium.
They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol
While less than 5% of the universe is made up of atoms, hydrogen and helium make up 98% of the atoms in the universe.
hydrogen undergoes nuclear fusion to form helium atoms
Yes it does. It produces helium by fusing hydrogen
fusion of hydrogen atoms into helium atoms
fusion of hydrogen atoms into helium
The sun is just a huge ball of hydrogen and helium. The heat created on the sun is from billions of hydrogen atoms smelting together to helium atoms. All these atoms are held together by the gravity.
No. Hydrogen atoms combining to form helium is nuclear fusion. Alpha decay is a process whereby a large atomic nucleus ejects a helium nucleus.
The sun is basically a giant ball of hydrogen and helium gases. In the sun's core, hydrogen atoms combine to form helium atoms. This process - called fusion - gives off radiant energy and is how hydrogen energy is formed.
Fusion, 2 hydrogen atoms turning into one Helium atoms continuously. (until the hydrogen runs out)
hydrogen and helium
NO, it can't break the sun light, because, the hydrogen atoms of the sun turn into helium that is by fusion process while the helium atoms turn into hydrogen
This is the fusing of hydrogen atoms to form helium atoms, and in some cases heavier elements as well. The dominant reaction in our Sun is the combining of hydrogen isotope atoms to form helium atoms. Deuterium atoms, which are hydrogen atoms which have a neutron, are forced together to form a helium atom, which is two protons and two neutrons, and some energy is produced. The Sun is slowing using up its supply of… Read More
2 hydrogen atoms
Hydrogen. creating helium. For every 1 hydrogen atom fused it creates 4 helium atoms
Stars make helium atoms by forcing hydrogen nuclei together.
Yes. Hydrogen atoms fuse together to form helium - releasing heat as a by-product. The helium atoms migrate from the centre of the sun to its surface - reverting back to hydrogen as they do so. The cycle repeats itself.
How Helium was Made Helium is made in nature when two Hydrogen atoms, (also a gas) combine at the atomic level. This combination can take place when Hydrogen particles collide at great speed or under extreme pressure. Helium is the second most abundant substance in the observable universe. Hydrogen is the most abundant. Helium is already 'made' and its only form is a gas. It is a natural gas and on the Periodic Table of… Read More
It is gravity.
yes and a few more but having the same basic atoms doesnt mean its the same thing. lipids contain carbon and hydrogen carbohydarates contian carbon and hydrogen as well but they also contain oxygen ratios of the number of certain atoms in them are differnet
Water is chemically H2O and there is no helium (He) in water. Water has two hydrogen atoms and one oxygen atom.
The fusion of two hydrogen atoms yielding a helium atom expels a large amount energy.
The sun produces energy by fusing hydrogen atoms into helium atoms. This is a nuclear fusion that occurs at the sun's core.
By nuclear fusion of helium. The intense gravity of the sun crushed the hydrogen atoms into helion. The energy economy of helium over two hydrogen atoms is released as heat and light.
