Carbon dioxide is a compound made up of the elements carbon and oxygen. Its chemical formula is CO2, which specifies that one molecule of CO2 contains one carbon atom and two oxygen atoms.Know More
Carbon dioxide is a colorless gas found in Earth's atmosphere. Its molecular weight is 44.01 grams per mole, and it is an oxide. Carbon dioxide has a boiling point of -78 degrees Celsius, and a melting point of -56.5 degrees.
Many applications in everyday life, such as in carbonated beverages and fire extinguishers, require carbon dioxide. In its solid phase, carbon dioxide is called dry ice, and is used for the creation of fog in theatrical performances. Carbon dioxide in the atmosphere is also important for the photosynthesis of plants.Learn more about Atoms & Molecules
Scottish physician and chemist Joseph Black discovered carbon dioxide on June 11, 1754. He noticed that heating calcium carbonate produced a gas much heavier than air. He also noted that it could put out fire. He called the gas "fixed air."Full Answer >
It is colorless and odorless, and it has a freezing point of -55.6 degrees Celsius. Carbon dioxide is soluble in water, acetone and ethanol. It is an atmospheric gas that is produced by both combustion and respiration.Full Answer >
Carbon dioxide is a compound formed by the sharing of two pairs of electrons between each of the two atoms of oxygen and one atom of carbon. This leads to the formation of a double covalent bond between the atoms of oxygen and carbon.Full Answer >
The density of carbon dioxide at STP is 1.964 grams per liter (g/L). One mole of an ideal gas at standard temperature and pressure has the volume 22.4 liters. The mass of the ideal gas can be calculated using its molecular weight: density = molar mass/molar volume.Full Answer >
