What else can I help you with?
Why are you running out of helium?
I'm personally not running out of helium. In fact helium is harmful to the human body in large doses. So no helium would not affect me.
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
Is a helium atom held together by a strong nuclear force?
Yes, a helium atom is held together by the strong nuclear force between its protons and neutrons in the nucleus. This force is what overcomes the electrostatic repulsion between positively charged protons to keep the nucleus stable.
Why does a steel tank filled with helium gas not rise in air?
A steel tank filled with helium gas does not rise in air because the weight of the tank and the helium gas inside is still greater than the buoyant force acting on it. The buoyant force is the force that causes objects to float in a fluid, like air. Since the tank is heavy and the helium gas is not strong enough to lift it, the tank remains on the ground.
What is the mass of 18.8 moles of helium (He) atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
Is helium strong or brittle?
Helium is a gas . . . it has neither strength nor brittleness.
Why does the sun have heat?
The sun is a big ball of hydrogen and helium. It's gravity is so strong that the inside squashes the hydrogen into helium releasing light in every part of the electromagnetic spectrum and part of it is infra red which is heat in the form of light.
Can helium lift 72 pounds into the air?
Yes, if you have enough helium in a balloon that is large enough and strong enough to stand the strains involved.
Why are you running out of helium?
I'm personally not running out of helium. In fact helium is harmful to the human body in large doses. So no helium would not affect me.
Forms 4 strong stable bonds?
Helium, Ne, Ar, Kr, Xe and Rn are stable bonds. Helium has 2 protons and 2 electrons.
Do atoms have strong attractions towards one another in a helium gas?
No, Helium is an inert or "noble" gas. It does not make chemical combinations with any other atoms.
What is helium mostly found in?
In helium balloons and blimps. Helium is lighter than air. So balloons or blimps filled with helium will float or rise up
How are companies getting helium and why is it so expensive?
Helium is extracted as a by-product of methane. Because the technology is difficult helium is expensive.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
What are helium's practical uses?
Helium is lighter than air. So balloons or air ships filled with helium will float.
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
