WebNitrogen gas is very common on the earth, as it comprises just over 75% of the molecules in air. Nitrogen gas, however, is very stable and difficult to break apart into individual nitrogen atoms. Usable nitrogen, in the form of ammonia or nitrate salts, is scarce.
Web23 Jul 2024 · The form of nitrogen in the atmosphere (i.e. nitrogen gas, N 2) is not very reactive and most living things cannot metabolize it directly. The unreactive nature of nitrogen gas is due to the triple bonds that bond the two nitrogen atoms. This bond cannot easily break; it takes higher energy to do so. Nitrogen gas alone cannot sustain life. celtic heroes androidWebR is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole (the pressure–volume product).
