Carbon dioxide is captured by trees and, using the photosynthesis chemical reaction, the carbon is stripped out of the CO2 molecule and added to a glucose molecule. The glucose is then used to form the cellulose of a tree's cell walls. When the tree is burned, it becomes coal, which is...
and scientists estimate that carbon is the keystone for 95% of known compounds, according to the websiteChemistry Explained. Carbon's incredible ability to bond with many other elements is a major reason that it is crucial to almost all life. ...
The positive anode oxidizes the oxygen of bauxite, which then reacts with the carbon electrode to form carbon dioxide:2O2- !’ O2 + 2e- O2 + C !’ CO2 This cathode must be replaced often because it is a part of the reaction. Despite the cost of electrolysis, aluminium is a very ...

Iron is necessary for the growth of phytoplankton — tiny marine bacteria that use carbon dioxide from the atmosphere to fuel photosynthesis. Some researchers have therefore argued that fertilizing the oceans with extra iron could help suck up excess carbon dioxide. But a study published online in ...
