Many physical and chemical properties of hydrogen depend on the parahydrogen/orthohydrogen ratio (it often takes days or weeks at a given temperature to reach the equilibrium ratio, for which the data is usually given). Hydrogen detonation parameters, such as critical detonation pressure and temperature, strongly depend on the container geometry.
Hydrogen forms weak bonds between molecules, latching onto adjacent oxygen, nitrogen or fluorine atoms. It's these hydrogen bonds that give water many of its properties. If they didn't exist, the boiling point of water would be below -70 degrees Celsius.

7 Ιουλ 2020 · Hydrogen is a combustible gas but is a non-supporter of combustion. When burnt, it burns with a pale blue flame in air or oxygen forming water. This reaction is highly exothermic (283kJ/mol) 2H 2 + O 2 → 2H 2 O. At high temperatures, hydrogen reacts with strong electropositive metals like Na, K, Ca, etc. to produce metal hydrides. H 2 + 2Na →2NaH.
3 Σεπ 2024 · Hydrogen is highly reactive. It combines with almost all elements to form binary compounds called hydrides. With Oxygen: 2H₂+O₂ →2H₂ O (to form water). With Chlorine: H₂ +Cl₂ →2HCl (to form hydrochloric acid). 2. Oxidation and Reduction. Hydrogen can undergo oxidation as well as reduction.
30 Οκτ 2024 · The two forms of hydrogen have slightly different physical properties. The melting point of para-hydrogen is 0.10° lower than that of a 3:1 mixture of ortho-hydrogen and para-hydrogen.
