Where is CO2 found?

CO2  is a minor component of the Earth's atmosphere. It can also be found in relative abundance on other planets in the solar system. 

 

What is the natural abundance of CO2  

Of the Earth's atmosphere, CO2 is about 3 volumes in 10,000 or about 370 ppm. The atmospheric level of carbon dioxide climbed from about 0.028 percent in 1860, to 0.0315 percent by 1958, and to 0.034 percent by 1981.

 

Percent composition by mass

27.29 % carbon, 72.71 % Oxygen

 

Density 1.527 kg/m3

 

Percent composition by number

For every one part Carbon, there are two parts Oxygen

 

Type of bonding

Carbon has a covalent, double bond with each of the two Oxygen atoms

 

Solubility

Carbon dioxide is slightly soluble in water (1.79 volumes per volume at 0º C)

 

Combustibility CO2  is virtually incombustible, it reacts with very few substances.
