Why atomic hydrogen is more reactive than hydrogen gas?
Hydrogen gas at standard temperature and pressure exists as diatomic molecules, and much of the chemical potential energy of atomic hydrogen has been evolved as heat along with forming the diatomic molecules.
What is the most abundant gas on mercury?
The most abundant gas on Mercury is oxygen. However, it exists primarily in the form of compounds like silicates and oxides rather than as a free gas. Mercury's thin atmosphere also contains trace amounts of helium, sodium, hydrogen, and potassium.
Does hydrogen exist as a diatomic?
Yes, hydrogen gas exists as a diatomic molecule with the formula H2.
Helium is a gas which is used in balloons because it is lighter than air.But hydrogen is a gas which is even lighter than the helium.Why helium is used rather than the hydrogen?
Because Hydrogen is highly flammable, and will easily and rapidly burn in the air and turn into H2O (water).
What is hydrogen fuel's chemical formula?
The chemical formula for hydrogen fuel is H2, which means it consists of two hydrogen atoms.
What space can 18000kg of hydrogen gas fill?
To do this we have to know the temperature of the gas and the gravitational field it exists in.
What is hydrogen bromine state?
Hydrogen bromine is a diatomic molecule that exists as a gas at room temperature and pressure.
Is hydrogen a gas at room temperature?
Yes, hydrogen is a gas at room temperature. It has a boiling point of -252.9 degrees Celsius, so it exists as a gas at typical room temperatures.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
Is argon gas made up of atoms or molecules?
Argon gas is made up of individual atoms of argon. It is a noble gas and exists as single atoms rather than as molecules.
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Is hydrogen different from water?
Yes. Hydrogen is an element. It usually exists as a light, highly flammable gas. Water is a compound of hydrogen and oxygen that can be produced by burning hydrogen.
