Helium is much less dense than air, which allows balloons to float. It is also chemically inert, which means hazards associated with it are minimal. Hydrogen gas is lighter and easier to obtain, which would make it seem ideal, but it is also highly flammable, which makes it dangerous.
What else can I help you with?
Why does the balloon rise?
because it contains helium that is lighter than air
What are the periodic elements in a balloon?
A balloon typically contains the element helium, which is a noble gas. It can also contain traces of other elements such as oxygen or nitrogen from the surrounding air or manufacturing process.
How much helium is in a balloon that contains 0.54 grams of gas?
0.54 grams 1 mol = mass / Mr = mass / 4 (Helium's atomic weight is 4, it is a monoatomic gas) 1 mol = 0.54 / 4 = 0.00135 # of molecules of helium in the balloon = 0.00135 * 6.02 * 10^23
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
Which gas do hot air balloons contain?
A hot air balloon contains helium. M. Saffi.Ullah
How much can a helium balloon lift?
depends how big the helium balloon is and how many
What happens if helium balloons explode when you bust it?
Helium is an inert gas and will not explode. If however your balloon contains Hydrogen gas (which is not inert) instead of Helium gas, and it comes into contact with a flame, it will blow up in your face. (You should google the Hindenberg some time)
What was the helium balloon balloon made of?
It was made out of the light gas gas Helium.
What is the answer for it already has helium but what is it?
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
Which balloon would fly higher the one with helium or the one with air?
The balloon with helium.
What makes a helium balloon?
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
