Carbon dioxide - Wikipedia
Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earths atmosphere as a trace gas.The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.
Carbon dioxide | CO2 - PubChem
An increase in carbon dioxide concentration stimulates the heart rate, increases the blood pressure, increases adrenalin flow, and relaxes the vascular smooth muscles. In addition, carbon dioxide reacts with water in the body to form carbonic acid, which dissociates to hydrogen ion and bicarbonate. An increase in carbon dioxide in the body increases acidity, and then the kidneys act to …

Carbon dioxide in Earths atmosphere - Wikipedia
Atmospheric carbon dioxide plays an integral role in the Earths carbon cycle whereby carbon dioxide is removed from the atmosphere by some natural processes such as photosynthesis and deposition of carbonates, to form limestones for example, and added back to the atmosphere by other natural processes such as respiration and the acid dissolution of carbonate deposits.
11 Sources That Give Off Carbon Monoxide In Your Home
Carbon monoxide, the silent killer. It’s colorless, odorless, and mere minutes of exposure at high levels can be lethal. It makes sense to take inventory of potential carbon monoxide risks around your home. But what exactly can give off carbon monoxide in your home?

Carbon Monoxide (CO) Poisoning in Your Home - EH ...
May 16, 2019 · Carbon monoxide (CO) is an odorless, colorless gas formed by the incomplete combustion of fuels. When people are exposed to CO gas, the CO molecules will displace the oxygen in their bodies and lead to poisoning. The Problem with CO Since CO has no odor, color or taste, it cannot be detected by our senses.
What Trees Absorb the Most Carbon Dioxide? | Hunker
Respiration is the process by which a tree takes in carbon dioxide and releases oxygen. The amount of carbon dioxide a tree can hold is called carbon sequestration. They sequester this carbon dioxide by storing it in their trunks, branches, leaves and roots; the best trees for carbon dioxide absorption will have large trunks and dense wood.
carbon dioxide | Definition, Formula, Uses, & Facts ...
At ordinary temperatures, carbon dioxide is quite unreactive; above 1,700 °C (3,100 °F) it partially decomposes into carbon monoxide and oxygen. Hydrogen or carbon also convert it to carbon monoxide at high temperatures.
