| carbon cycle |
the steps by which carbon (in the form of carbon dioxide) is extracted from the atmosphere by living organisms and ultimately returned to the atmosphere. It comprises a series of interconversions of carbon compounds beginning with the production of carbohydrates by plants during photosynthesis, proceeding through animal consumption, and ending and beginning again in the decomposition of the animal or plant or in the exhalation of carbon dioxide by animals.

| carbonate |
Carbonate is an anion with a charge of -2 and an empirical formula of CO32-. An aqueous solution of carbon dioxide contains a minute amount of H2CO3, called carbonic acid, which dissociates to form hydrogen ions and carbonate ions. It would be a fairly strong acid if carbonic acid existed in pure form, but the equilibrium favors carbon dioxide and so such solutions are fairly weak. ...

| carbonic acid |
Carbonic acid is a weak acid with the chemical formula of H2CO3. It is the reaction product of water and carbon dioxide and exists in an equilibrium with water and carbon dioxide whenever the latter is dissolved in the former, for instance in soda water or blood. It is usually not possible to obtain pure hydrogen bicarbonate as the presence of even a single molecule of water causes the carbonic acid to revert to carbon dioxide and water fairly quickly. ...

| carbon arc lamp |
An arc lamp is a device that produces light by the sparking (or arcing, from voltaic arc or electric arc) of a high current between two carbon rod electrodes. The rods are touched and then slowly drawn apart; as the rods separate the current is "struck" and arcs across the gap in a bright, ionized path. The arc produces a temperature of several thousand degrees, and the tips of the carbon rods are heated to incandescence, creating light. ...
