What else can I help you with?
Why is helium gas safer than hydrogen gas?
Because hydrogen is reactive and combines with oxygen, while helium is inert.
Helium safer than hydrogen?
Yes, because helium doesn't react, burn or explode.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
Which 2 gases are found in airships?
Hydrogen and helium gases are commonly used in airships for lift. Helium is safer than hydrogen due to its non-flammable nature, although it is less buoyant.
What is ligther helium or oxygen?
Helium---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Is helium lighter or heavier than hydrogen?
Heavier but safer. Look what happened to the Hindenburg:(
Which gas is heavier among argon oxygen and helium?
Argon is heavier than oxygen and helium. Argon has an atomic mass of 39.948 g/mol, while oxygen has an atomic mass of 16.00 g/mol and helium has an atomic mass of 4.003 g/mol. Argon is a noble gas that is denser than both oxygen and helium.
Why can helium escape the earth's atmosphere?
Helium is lighter than oxygen and can escape the ozone.
Does helium have smaller particles than nitrogen or oxygen?
Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas 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!
