Carbon is found throughout the earth. It is a major element in many rock formations such as limestone and marble. It is found in its allotropic forms of diamond, graphite, and amorphous carbon throughout the world.
Thereof, where is carbon dioxide?
Carbon naturally moves from one part of the Earth to another through the carbon cycle. But right now, by burning fossil fuels, people are adding carbon to the atmosphere (in the form of carbon dioxide) faster than natural processes can remove it.
Where is carbon dioxide produced?
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. This energy is our physical "life force". Both oxygen and glucose are required for this.
Where was carbon dioxide discovered?
Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. Carbon dioxide is a molecule with the molecular formula CO2.
