The Carbon Cycle | Biology for Majors II

Thus, the "carbon footprint" is based on how much carbon dioxide is produced and how much fossil fuel countries consume. The carbon cycle is most easily studied as two interconnected sub-cycles: one dealing with rapid carbon exchange among living organisms and the other dealing with the long-term cycling of carbon through geologic processes.

US20060039853A1 - Separation of carbon dioxide (CO2) from .

A reaction-based process has been developed for the selective removal of carbon dioxide (CO 2 ) from a multicomponent gas mixture to provide a gaseous stream depleted in CO 2 compared to the inlet CO 2 concentration in the stream. The proposed process effects the separation of CO 2 from a mixture of gases (such as flue gas/fuel gas) by its reaction with metal oxides (such as calcium oxide).

Air pollution control - Control of gases | Britannica

Storing carbon dioxide underground—a technology under development that is also called geosequestration or carbon capture and storage—would involve pumping the gas directly into underground geologic "reservoir" layers. This would require the separation of carbon dioxide from power plant flue gases (or some other source)—a costly process.

Carbon dioxide is a very soluble. gas. It dissolves readily in water. As the oceans formed, carbon dioxide dissolved to form soluble carbonate compounds so its amount in the atmosphere decreased.

What happens when acid reacts with limestone? | Questions .

Jun 15, 2008 · The classic test for carbon dioxide is that, when bubbled through limewater, the solution turns milky. This is because the limewater - which is calcium hydroxide - Ca(OH) 2 - reacts with carbon dioxide to form calcium carbonate - CaCO 3 which is insoluble; this precipates as fine particles, which impart a milkiness to the solution.

The Slow Carbon Cycle - NASA Earth Observatory

However, the slow carbon cycle also contains a slightly faster component: the ocean. At the surface, where air meets water, carbon dioxide gas dissolves in and ventilates out of the ocean in a steady exchange with the atmosphere. Once in the ocean, carbon dioxide gas reacts with water molecules to release hydrogen, making the ocean more acidic.
