Carbon dioxide(CO2)

* carbon dioxide, (CO2), a colourless gas having a faint sharp odour and a sour
taste
...
The presence of the gas in the atmosphere keeps some of the
radiant energy received by Earth from being returned to space, thus producing
the so-called greenhouse effect
...


* Carbon dioxide was recognized as a gas different from others early in the 17th
century by a Belgian chemist, Jan Baptista van Helmont, who observed it as a
product of both fermentation and combustion

4 °F) or
to 16–24 kg per sq cm (230–345 lb per sq in

By
the mid-20th century, most carbon dioxide was sold as the liquid
...
5 °C (−109
...

* At ordinary temperatures, carbon dioxide is quite unreactive; above 1,700 °C
(3,100 °F) it partially decomposes into carbon monoxide and oxygen
...
Ammonia reacts
with carbon dioxide under pressure to form ammonium carbamate, then urea, an
important component of fertilizers and plastics
...
79 volumes per volume at 0 °C and atmospheric pressure, larger
amounts at higher pressures), forming a weakly acidic solution
...

* Carbon dioxide is used as a refrigerant, in fire extinguishers, for inflating life
rafts and life jackets, blasting coal, foaming rubber and plastics, promoting the
growth of plants in greenhouses, immobilizing animals before slaughter, and
in carbonated beverages
...
Prolonged exposure of humans to
concentrations of 5 percent carbon dioxide may cause unconsciousness and
death
