Because of an accident that happened. A weather balloon was filled with hydrogen and when lightning hit it, it set on fire. Hydrogen is flammable, so they use Helium instead, because Helium is a nobel gas and so isn't flammable, but also lighter than air so the balloon floats.
What else can I help you with?
Why helium exist in the form of he not he2?
he2 is a fatty. He atom is a inert gas. so it can not react with any other atom or molecules to form any compounds.so He2 can't exist. ANOTHER ANSWER: Helium atom has only one shell i-e K-shell which can accommodate a maximum of two electrons which it already has. therefore Helium atom does not need any more electrons to become stable as it is already stable by duplet rule. Thus helium atom does not combine with another helium atom and hence exists as He and not He2.
When an area is experencing several consecutive days of rather constant weather it is probably?
air-mass weather
How would you rank the nuclear fuels in order of being consumed from first to last with the following fuels carbon hydrogen and helium?
First it should be emphasized that hydrogen and helium are not primary energy sources. They are named as secondary energy sourcesCarbon from coal has limited resources as any fossil fuel (although coal is more abundant than oil and natural gas)As for the nuclear fuel, the uranium mining is not the only source for the nuclear fuel. Other sources are:as by product from phosphate and gold production industrythe dismantling of nuclear weaponsusing nuclear breeder reactorsuranium production from water (Japanese R&D)The availability of uranium for uranium fuel persuades some scientists to consider nuclear energy as one of the renewable energy sources.
Is helium a molecule?
Helium is an atom. Heavier elements have molecules.
What is the charge of hydrogen peroxide?
As H2O2 it is uncharged , but rather unstable., and will slowly decompose to water and oxygen.
Why are birthday balloons filled with helium rather than hydrogen?
Helium is non-flammable, so it is safer than hydrogen for filling balloons. Hydrogen gas is highly flammable and can pose a fire hazard, especially in the presence of heat or flame. Consequently, helium is the preferred gas for inflating balloons, as it is a safer option.
Helium is a gas which is used in balloons because it is lighter than air.But hydrogen is a gas which is even lighter than the helium.Why helium is used rather than the hydrogen?
Because Hydrogen is highly flammable, and will easily and rapidly burn in the air and turn into H2O (water).
Why balloons are filled with helium?
Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium. Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.
Hydrogen plus hydrogen helium?
When two hydrogen atoms react, they can combine to form helium through nuclear fusion. This process releases a tremendous amount of energy and is the basis for the power source of the sun and other stars.
How many atoms of hydrogen are need to create 1 atom of helium?
2, but its an isotope of hydrogen with a mass of 2 rather then 1.09
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.
Why is helium used in airships rather than oxygen?
Helium is a lighter gas than oxygen, ever seen balloons filled with helium? They rise upwards with heat due to a lesser amount of particles. If we used oxygen, the airships wouldn't get off the ground!
What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Why is dihydrogen gas not preferred in balloons?
# flammable, a fire hazard # irritating, a health hazard # hydrogen has a disturbing ability to leak out through the matrix of rubber so a hydrogen balloon deflate rather quickly.
Will a helium balloon float in below freezing weather?
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
Why is helium used in hot air balloon?
It isn't. Hot air Ballons use Hot Air. Hot air being lighter and therefore less dense than normal air allow the balloon to float.
Can helium be used in hiking?
Helium cannot be used for hiking as it is a non-reactive gas and does not provide any benefit in terms of breathing or energy. It is typically used for filling balloons, scientific research, and medical applications, rather than outdoor activities like hiking.
