There is, for all practical purposes, no hydrogen in the Earth's atmosphere (somewhere around 50 parts per million). Oxygen makes up roughly 1/5 of the atmosphere.
So, no. There is much more oxygen than hydrogen in the air.
There is no real answer. The equation of water is : H2O so it's two parts hydrogen and 1 part oxygen.
There is more nitrogen in the atmosphere but oxygen is the most abundant element in the earth's crust.
because there are less trees to give out oxygen because these twats have cut them down this is written by a emo :')
Yes. Dry air is 78% nitrogen, 21% oxygen and 0.04% carbon dioxide.
hydrogen is more than helium in air.
yes
When water splits, hydrogen gas and oxygen gas are formed.
They are both diatomic gases. Hydrogen will explode in oxygen to produce water.
oxygen and hydrogen are a type of matter called gas
Hydrogen has a much lower attraction for electrons than oxygen does (or in more technical terms, oxygen has a much higher electronegativity). So when hydrogen gives up an electron to oxygen, it creates a strong chemical bond (although not an ionic bond; hydrogen's electronegativity is too high for that). When hydrogen peroxide gives up excess oxygen, the hydrogen remains bonded to the remaining oxygen (since hydrogen peroxide becomes water, H2O). If instead the hydrogen peroxide were to give up hydrogen, you would lose the powerful bond between hydrogen and oxygen, and all you would get in exchange would be a much weaker bond between hydrogen atoms and other hydrogen atoms, in the diatomic hydrogen molecule. Chemical reactions move in the direction of the strongest available bonds.
If you add thermal energy to a mixture of oxygen gas and hydrogen gas, water will be produced in the form of water vapor.
oxygen gas is heavier than hydrogen gas
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
Hydrogen burns in Chlorine to form HCl. Thus, CHLORINE gas supports the burning of Hydrogen.
Hydrogen and oxygen are the products of electroysis of water .
The reaction equation is: 2H2 + O2 = 2H2O So one need two volume part of hydrogen and one volume part of oxygen to form water.
Hydrogen gas is H2. Oxygen gas is O2.
The pressure in a gas cylinder containing hydrogen will leak more quickly than oxygen. REASON & EXPLANATION: According to graham law of diffusion, the rate of diffusions of certain gas is inversely proportional to its molecular mass and density. i. e. smaller the molecular mass and density,greater will be the rate of diffusion and vice versa. As the hydrogen is lighter than the oxygen, so the molecular mass and density is lower than that of oxygen, so the pressure in a gas cylinder containing hydrogen will leak more quickly than if it is containing oxygen.
This question answers itself. The products of a reaction PRODUCING hydrogen and oxygen are, well, hydrogen and oxygen!If you are asking what hydrogen and oxygen are made FROM, than the REACTANT is water. If a voltage is applied to water, hydrogen and oxygen gas are made.If you are asking what the product of a reaction is when hydrogen and oxygen are the REACTANTS, then the answer is also water.See the Related Questions for more information to the left of this answer.
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
I'm not sure of the exacts, but I'm fairly sure that oxygen is more reactive than hydrogen. For example, when testing with a smoldering wood splint, in the presence of oxygen gas the flame is reignited, while in the presence of hydrogen gas the splint simply glows. Again, not sure of the exacts myself, but it may have something to do with the fact that oxygen is diatomic and has a double bond with itself, leaving each oxygen atom with two unbonded pairs of valence electrons, making it more reactive. Hydrogen is also diatomic, and that means that each hydrogen atom is used in the single covalent bond, leaving it with no unbonded valence electrons, making it presumably less reactive than oxygen.
When water splits, hydrogen gas and oxygen gas are formed.
