what property of hydrogen prevents hydrogen gas from being used in balloons?

Answer 1

It takes a strong balloon fabric to prevent it leaking out quickly, and it can be explosive if you light it.

Answer 2

It is used occasionally. The difficulty is that it will burn in any air concentration from almost 3% to 95%. The only reason the gasoline in fuel tanks normally doesn't explode is that the combustible range is much narrower, about 22 to 27%. Anything outside the range won't sustain combustion. Most people are still freaked by the Hindenburg thing even though if I had to choose between being near a hydrogen explosion or a propane explosion I'd definitely take the hydrogen one as propane is heavier than air and settles and so would go around you where the hydrogen tends to rise above. There is considerable evidence, including the film of the event that most of the fatalities were caused by burning fabric and falling structure.
Have to laugh at myself. So used to thinking man carrying that I didn't think of party balloons.

Answer 3

The big problem is that It has a very small molecular size, and it leaks through the side of ordinary latex balloons. Helium is a much larger molecule. Besides, you can play with helium-speak at the party.

While flammability of hydrogen makes it an unpopular choice for zeppelins, the amount of hydrogen in an ordinary balloon is so small that it's no more dangerous than having beans for supper.

Answer 4

Hydrogen is a flammable gas therefore might burst into little children's face (squeeky pop)...
and also an average balloon is not strong enough to contain the gas as it will leak out too easily!
Why dnt u just use helium? it works fine lol

Answer 5

Hydrogen gas is a dangerous and volitile substance. It cannot be emphasized enough to go to great efforts to ensure your own safety while doing anything with it.
If that warning does not impress you, try to remember one word: HINDENBERG. This was the German Zeppelin that went down in flames.
It was filled with hydrogen gas. It was the reason why we use helium gas now for our blimps and childrens' balloons.

Answer 6

It's flammable, in high concentrations, it can be a simple asphyxiant.

Answer 7

flammability

Answer 8

Boom!
