- Carbon dioxide (chemical formula CO2) is a colorless, odorless gas vital to life on Earth. This naturally occurring chemical compound is composed of a carbon atom covalently double bonded to two oxygen atoms.arbon dioxide was the first gas to be described as a discrete substance. In about 1640, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal.

Carbon dioxide in Earth's atmosphere Carbon dioxide in Earth's atmosphere. Carbon dioxide (CO2) is an important trace gas in Earth's atmosphere. CO2 is a major greenhouse gas and plays a vital role in regulating Earth's surface temperature through radiative forcing and the greenhouse effect. Carbon dioxide is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis.

Carbon Dioxide Carbon Dioxide, CO2, is a tasteless, colorless, odorless, nonflammable, liquefied gas. Carbon dioxide is an integral part of the basic life cycle in nature. It is exhaled by humans and animals, then used by plants to help them grow. Plants, in turn, release oxygen, which people depend on for survival.

Carbon dioxide Atmospheric carbon dioxide is the primary source of carbon in life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian was regulated by photosynthetic organisms and geological phenomena.s the concentration of carbon dioxide increases in the atmosphere, the increased uptake of carbon dioxide into the oceans is causing a measurable decrease in the pH of the oceans, which is referred to as ocean acidification.

Carbon dioxide Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread, beer and winemaking. It is produced by combustion of wood, carbohydrates and fossil fuels such as coal, peat, petroleum and natural gas.arbon dioxide dissolves in the ocean to form carbonic acid (H 2 CO 3), bicarbonate (HCO 3 −) and carbonate (CO 3 2−). There is about fifty times as much carbon dissolved in the oceans as exists in the atmosphere.

This naturally occurring chemical compound is composed of a carbon atom covalently double bonded to two oxygen atoms.emoglobin, the main oxygen-carrying molecule in red blood cells, carries both oxygen and carbon dioxide. However, the CO 2 bound to hemoglobin does not bind to the same site as oxygen. Instead, it combines with the N-terminal groups on the four globin chains.

Carbon dioxide At −78.51 ° C or −109.3 ° F, carbon dioxide changes directly from a solid phase to a gaseous phase through sublimation, or from gaseous to solid through deposition. Solid carbon dioxide is normally called  dry ice , a generic trademark. It was first observed in 1825 by the French chemist Charles Thilorier.

Carbon dioxide Carbon dioxide is a molecule with the molecular formula CO 2. The linear molecule consists of a carbon atom that is doubly bonded to two oxygen atoms, O=C=O. Although carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form.It can only be solid when temperatures are below -78 oC.lthough carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form. It can only be solid when temperatures are below -78 o C. Liquid carbon dioxide mainly exists when carbon dioxide is dissolved in water. Carbon dioxide is only water-soluble, when pressure is maintained.

Air mass Cold fronts and occluded fronts generally move from west to east, while warm fronts move poleward. Because of the greater density of air in their wake, cold fronts and cold occlusions move faster than warm fronts and warm occlusions. Mountains and warm bodies of water can slow the movement of fronts.

Difference Between Oxygen and Carbon Dioxide Carbon dioxide is a molecule form from a carbon atom and two oxygen atoms. Each oxygen atom forms a double bond with carbon, and the molecular has a linear geometry. The molecular weight of carbon dioxide is 44 g mole-1. Carbon dioxide (CO2) is a colorless gas and upon the dissolution in water, it forms carbonic acid. Carbon dioxide is denser than air.
