Hydrogenation is the addition of molecular hydrogen (H2) to a multiple bond, which converts alkenes to alkanes.
This reaction results in the production of carbon dioxide, molecular hydrogen (H2), and ATP.
(Water, in fact, is the second most abundant molecule in the universe, after molecular hydrogen).
But in the Jan . 4issue of the journal Nature, American and European astronomers reported new observations of molecular hydrogen in these disks showing greater than expected reservoirs of gas on which emerging Jupiter-class planets could draw.
"Jupiter's magnetic field may be generated by the layer of liquid metallic hydrogen in the planet's interior, but another school of thought says it may be generated from a layer of molecular hydrogen above that.
The largest chemical effect of dust is to provide the only site of molecular hydrogen formation on grain surfaces.
Ultraviolet photons with energies of more than 11.2 electron volts can dissociate molecular hydrogen (H2) into two H atoms.
But how long did it take molecular hydrogen to form?
As much as 2 x 1014 grams of molecular hydrogen may also be produced.
Many different bacteria generate molecular hydrogen (H2) as a fuel source for their own metabolism.
"It turns out that molecular hydrogen forms faster than previously thought," Savin says.
