This molecule's relatively low critical temperature of 304 kelvins allows its use as the mobile phase in supercritical chromatography.
A laser from this molecule has a peak at about 10.6 micrometers and attains population inversion by energy transfer from excited N2 molecules. The first step of the Solvay process involves reacting sodium chloride, ammonia, water, and this compound. This molecule's relatively low critical temperature of 304 kelvins allows its use as the mobile phase in supercritical chromatography. Its supercritical form is also forced through (*) coffee beans to extract caffeine. Hemoglobin's affinity for oxygen in the blood is inversely related to the concentration of this gas in the Bohr effect. It is the major cause of ocean acidification and is produced, along with water, in combustion reactions. For 10 points, name this molecule whose solid form is dry ice.
