Why do starts need helium?
stars* and they don't need helium they make helium from hydrogen using nuclear fusion omg im 13 and i know this
Why does your body need helium?
Your body does not need helium. Helium is an inert gas, and it is not found as a "building block" of any organic material, or any other materials for that matter.
What is helium ions?
Helium ions can be synthesized by removing electrons from a helium atom and it would need a tremendous energy.
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
How much helium would it take to lift 2000lbs?
to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
Do you need helium to make a balloon float?
Yes.
How many moles of Helium are in 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
Can helium be used in hot air balloons?
YES!!! However, there is no need to heat the helium. It is a light gas. and it is an inert gas.
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.
How many helium atoms are in 542 kg of helium?
To find the number of helium atoms in 542 kg of helium, you need to first calculate the number of moles of helium in 542 kg using the molar mass of helium, which is 4 grams/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of helium to atoms.
Can we use helium as Fire extinguisher?
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
Do they use liquid helium for balloons?
No, in order for helium to be kept as a liquid it would need to be kept at a temperature of -268.93 degrees celsius.This is both highly difficult, and impracticle, therefore helium is stored and dispensed as a gas.
