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!

∙ 13y agoOnly noble gas Helium (mass 4) is safe and suitable to use,
Neon (mass 20) also but is a bit heavier,
but Argon (mass 40) is much TOO heavy
(all masses are compared to air which has a mass of 28.8 g/mol)
Do NOT ever use the lightest gas Hydrogen because it is VERY, VERY explosive.

∙ 6y agoAir is safe to use in a balloon as is Carbon Dioxide and Nitrogen. Oxygen and hydrogen would be unsafe and while Helium is also safe, one should not use it because it is a rare gas that is needed for medical purposes and should not be wasted in balloons.

∙ 12y agoMost definite helium lots of our galaxy is made of it.. (He) on the Periodic Table falls under the category noble gas. It's non-toxic, oder, and tastless... your welcome =P

∙ 14y agoyes, it is safe but Helium is costly and not easily available
Wiki User
∙ 11y agohelium is a safer choice than hydrogen because helium is very reactive with oxygen while hydrogen is not
Wiki User
∙ 10y agoGases used are helium, hot air (normal air for children balloons) or hydrogen.
The safest is helium but also is the most expensive.

What chemical property of helium makes it a better choice than hydrogen for use in airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
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
Is a piece of aluminium foil a permeable membrane?
depend upon your choice , hydrogen permeable but water not
Why the standard potential of standard hydrogen electrode is taken as zero?
Because we can only measure relative potentials, so we need to designate some point as zero. Hydrogen is a pretty good choice, since that way we can tell whether a given substance will react with acids to liberate hydrogen or not just based on the sign of the half-cell potential.
Why cant you use liquid hydrogen as fuel?
You can use liquid H2 as fuel. NASA has been doing it since the 1960's. However, the handling and storage of liquid hydrogen is challenging, and may not be within the capability of the average person to safely manage in a personal vehicle. Liquid hydrogen could be a fuel of choice for professionally managed public transit such as busses and trains.
Will nitrous oxide float in a balloon?
No, nitrous oxide has a density of around 1.977 grams/liter, "air" at sea level has a density of 1.2 grams/liter, meaning that nitrous oxide is more dense than air. Helium on the other hand has a density of 0.1785 grams/liter, making it less dense than air... Also making helium a popular choice for filling balloons. Hydrogen is another common balloon filling gas. Although it is highly flammable. (Hindenburg)
Where can one find personalized birthday balloons?
Personalized birthday balloons can be found at Party City, Fast Balloons, Balloons Tomorrow, Zoom Balloon and 1-800-Balloons. Personalized balloons at Party City can range from $3.99 to $9.99.
What are some of the most popular varieties of balloons used in weddings?
Latex personalized balloons are very popular for weddings today. Photos and personalized messages can be ordered. Another popular choice is the helium filled mylar balloons. These are the metallic floating balloons.
How does a voter register a choice in a statewide election?
by filling out a ballot
Why don't they use hydrogen gas in airships nowadays?
hydrogen is VERY flammable, which makes it an unpleasant choice.
What brand of duvet is the warmest?
The threadcount, fill power, and type of filling dictate how warm a duvet will be. A duvet with goose down filling is going to be the best choice for warmth.
Why is helium used to fill balloons?
It is a matter of mass, weight, and density. A balloon filled with normal air will not rise. Air will rise in water, because it is less dense (bubbles). Helium on the other hand is lighter than air, so it too will rise when 'submerged' in it. The actual process is that the heavier air surrounding a helium-filled balloon will "displace it" and force it upward. Hydrogen is also less dense than air, but it is flammable. Helium is not flammable, has no smell or taste, and is not poisonous. So because it is the second lightest element, and the second most plentiful in the world (found in natural gas), it's a natural fit. ---- However, consider that while it may seem fun to have balloons that go up on a string, if they escape, then eventually they pop and it is likely that the burst rubber will fall into the sea. In the sea they are mistaken for food by turtles and escaped balloons cause much harm. Also being unreactive as an element and very light, most of the helium on earth has gone to the top of the atmosphere and escaped into space. The only helium we have is found as a byproduct of radioactive decay within the Earth. The element has very important uses in industry and science and wasting it on balloons is not a sensible thing to do. There is only a finite amount of helium available to us at any given time.
where can I buy a balloons bouquet in Ohio?
That would depend on where in Ohio you reside. If you are near Columbus, then Balloonsrbetter.com would be a good choice. If you're near Dayton, then Balloonsgalore.net would be a great choice.
Is hydrogen gas a safe storage environment for food products such as rice?
Hydrogen is flammable, so that would be a so-so choice. Something inert, nike Nitrogen would be a better choice.
