Hydrogen gas has been largely replaced with helium gas in applications like ballooning and airships primarily due to safety concerns. Hydrogen is highly flammable and poses explosion risks, while helium is non-flammable and safer to use. Additionally, helium is less reactive, making it a more stable choice for various applications. Although helium is more expensive, its safety advantages outweigh the cost for many uses.
What else can I help you with?
Why hydrogen gas is liquefied first than helium gas?
Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.
Which chemical symbol is used to represent gas helium?
The symbol for hydrogen gas is H2
Which of these is NOT a noble gas argon hydrogen helium neon?
Hydrogen is not a noble gas.
Is an inert gas and has one more proton than hydrogen?
The gas is helium. Helium is inert and has 2 protons, while hydrogen has 1 proton.
Why helium gas is used in weather balloons but not hydrogen?
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
What is a noble gas hydrogen helium or carbon?
helium is a noble gas

Why is Helium gas used in gas balloons instead of hydrogen gas?
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
Which of these is NOT a noble gas argon hydrogen helium neon?
Hydrogen is not a noble gas.
What state will the elements chlorine helium hydrogen and oxygen be at room temperature?
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: gas
Is an inert gas and has one more proton than hydrogen?
The gas is helium. Helium is inert and has 2 protons, while hydrogen has 1 proton.
Was helium the lightest gas?
Hydrogen was, and is, the lightest gas
What is gas from the sun?
hydrogen and helium
What is the sun gas?
they are hydrogen and helium .
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen
Why helium gas is used in weather balloons but not hydrogen?
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
