Carbon dioxide - Wikipedia, the free encyclopedia

Carbon dioxide (chemical formula: CO 2) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state.. Within the atmosphere it is currently at a globally averaged concentration of approximately 387 ppm by volume. [1] [2] Atmospheric concentrations of carbon dioxide ...

Carbon dioxide — Wikipedia Republished // WIKI 2

Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (410 ppm) by volume, having risen from pre-industrial levels of 280 ppm. Natural sources include ...

Carbon monoxide, with the chemical formula CO, is a colorless, odorless, and tasteless gas. It consists of one carbon atom covalently bonded to one oxygen atom. It is made when carbon compounds burn and there is not enough oxygen. It is a good fuel and burns in air with a blue flame, making carbon dioxide.

Carbonic acid - Wikipedia

In chemistry, carbonic acid is a dibasic acid with the chemical formula H 2 CO 3.The pure compound decomposes at temperatures greater than ca. −80 °C. In biochemistry, the name "carbonic acid" is often applied to aqueous solutions of carbon dioxide, which play an important role in the bicarbonate buffer system, used to maintain acid–base homeostasis.

Carbon - Simple English Wikipedia, the free encyclopedia

Carbon is the fourth most common element in the sun. The atmospheres of Venus and Mars are mostly carbon dioxide. Carbon is important to the human body and other living things, and it is the second most common element in the human body, at 23% of all body weight. It is also a key part of many biological molecules (molecules used in life).

Estimates of carbon dioxide changes through geochemical modeling instead rely on quantifying the geological sources and sinks for carbon dioxide over long time scales particularly: volcanic inputs, erosion and carbonate deposition. As such, these models are largely independent of direct measurements of carbon dioxide.

Photorespiration - Wikipedia

Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C 2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.The desired reaction is the addition of carbon dioxide to RuBP (carboxylation), a key step in the Calvin–Benson cycle, but approximately 25% of reactions by ...

Breathing - Simple English Wikipedia, the free encyclopedia

Breathing helps people do two very important things: Get oxygen into the body. Every part of the body needs oxygen to survive. The only way humans can get oxygen is to breathe it in.; Get carbon dioxide (CO 2) out of the body.When the body makes energy, carbon dioxide gets left over.The body needs to get rid of extra carbon dioxide, because too much of it is poisonous.

Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules. Photosynthesis is very important for life on Earth.

Carbon capture and storage - Wikipedia

Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO 2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia.Usually the CO 2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an underground geological formation.

The respiratory system, also called the gas exchange system, is the body getting rid of carbon dioxide and taking in oxygen.Carbon dioxide, a waste product, goes out of the body. Oxygen, which the body needs, comes in. The lungs are the main organ to do this. In other words, the process in which oxidation of organic compounds occurs in cell and energy is released is called the Respiratory system.
