helium does not burn, hydrogen will burn in air
That depends. What are you proposing to use it for?
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
A star, like the sun, spends much of its life producing energy, in the form of light and heat, through the fusion of hydrogen into helium. When the hydrogen is mostly used up the star moves to fusion of helium into larger (heavier) elements. At that stage the sun will become a red giant. It will then be large enough to engulf the earth's orbit, thyough well before that happens, the earth will be a burnt, lifeless "cinder".
Helium is used in balloons instead of hydrogen because it is non-flammable. Hydrogen is flammable and can be dangerous, while helium is inert and poses less of a fire risk. Additionally, helium is less dense than air, providing better lift for balloons.
The symbol for hydrogen gas is H2
Hydrogen is extremely flammable and helium is safer.
Hydrogen (explosive), Helium (non-explosive).
Helium is used instead of hydrogen in balloons because it is non-flammable, while hydrogen is highly flammable. This makes helium a safer option for filling balloons to prevent any potential fire hazards. Additionally, helium is also lighter than air, allowing balloons to float easily.
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Helium is used to reaplce hydrogen on a n airplane because it is nonflammable
The propellant used in hair spay does not contain hydrogen gas or helium gas. Hairspray contains compounds that contain covalently bonded hydrogen.
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
