What is carbon Dioxide (CO2)

Carbon Dioxide is 1 Carbon atom with 2 Oxygen atoms. C (Carbon) 02 (Oxygen x2)

di-1


a prefix occurring in loanwords from Greek, where it meant “two,” “twice,” “double” (diphthong); on this model, freely used in the formation of compound words (dicotyledon; dipolar) and in chemical terms (diatomic; disulfide).

Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions.

Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth’s atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.[8] Natural sources include volcanoeshot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwaterrivers and lakesice capsglaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide is odorless at normally encountered concentrations, but at high concentrations, it has a sharp and acidic odor.[1]

Carbon Dioxide in the earth’s Atmosphere

Atmospheric composition (by volume, dry air):

Major: 78.08% Nitrogen (N2), 20.95% Oxygen (O2),
Minor (ppm): Argon (Ar) – 9340; Carbon Dioxide (CO2) – 410, Neon (Ne) – 18.18; Helium (He) – 5.24; CH4 – 1.7 Krypton (Kr) – 1.14; Hydrogen (H2) – 0.55

Numbers do not add up to exactly 100% due to roundoff and uncertainty Water is highly variable, typically makes up about 1%
