  2. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

  3. Vapour density - Wikipedia

    en.wikipedia.org/wiki/Vapour_density

    It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen gas . vapour density = molar mass of gas / molar mass of H 2 vapour density = molar mass of gas / 2.01568 vapour density = 1 ⁄ 2 × molar mass (and thus: molar ...

  4. Hydroperoxyl - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxyl

    Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.

  7. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The difference is that molecular mass is the mass of one specific particle or molecule, while the molar mass is an average over many particles or molecules. The molar mass is an intensive property of the substance, that does not depend on the size of the sample. In the International System of Units (SI), the coherent unit of molar mass is kg ...

  8. Hydroperoxide - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxide

    This hydrogen peroxide then releases hydrogen peroxide: [(HO) 3 B(OOH)] − + H 2 O ⇌ B(OH) − 4 + H 2 O 2. Several metal hydroperoxide complexes have been characterized by X-ray crystallography. Some form by the reaction of metal hydrides with oxygen gas: [17] L n M−H + O 2 → L n M−O−O−H (L n refers to other ligands bound to the ...

  9. Liquid rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_propellant

    Hydrogen's buoyancy. Since hydrogen is a deep cryogen it boils quickly and rises, due to its very low density as a gas. Even when hydrogen burns, the gaseous H 2 O that is formed has a molecular weight of only 18 AMU compared to 29.9 AMU for air, so it also rises quickly. Spilled kerosene fuel, on the other hand, falls to the ground and if ...
