How much volume would a kilogram of gaseous hydrogen take up?
Depends on the pressure and temperature.
Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
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.
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.
Out of hydrogen water and oxygen which one has the highest density?
At standard temperature and pressure, water has much the highest density, because it is a liquid and the other two are nearly ideal gases.

Is hydrogen less dense than air?
Yes, much lighter. The density of hydrogen is 0.08988 grams per litre, at standard temperature and pressure at sea level. The density of air is 1.22521 grams per litre, at the same temperature and pressure.

What is the luster of hydrogen?
The element hydrogen does have a metallic form, which exists under conditions of both low temperature and high pressure. Under more usual conditions hydrogen is a gas and as such, has no luster. As a metal it has a metallic luster much like other metals.
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.

How is hydrogen stored in a Rocket?
Hydrogen is stored in liquid form in a tank, at low temperature. It would not be practical to store it as a gas, since it would take up too much space, or if sufficiently compressed, would have an excessively high pressure.
Does C2H5OH have hydrogen bonds?
C2H5OH is the formula for ethanol, an organic compound. Hydrogen bonds are possible for ethanol at the intermolecular level, between molecules, but not for the intramolecular carbon-hydrogen or the oxygen-hydrogen bonding within the molecule. Hydrogen bonds are much weaker than true chemical bond.A good example of a hydrogen bond is that which makes water a liquid at normal temperature and pressure.
How much temperature hydrogen bomb can create?
10s of millions of degrees.
Does the nuclear fusion occurs at the surface of the sun?
Fusion takes place in the core, where the temperature and pressure are much higher, which is necessary for fusion.
Why is it unsafe to much hydrogen gas without testing?
Hydrogen is an explosive gas in contact with oxygen and at high temperature.
