A gas consisting of one atom of carbon and two of oxygen. It is a product of oxidation of organic compounds. It is the principal metabolic product contained in the air we exhale.
A colourless, odourless non-poisonous gas, normally part of ambient air; a result of fossil fuel combustion.
a colorless, odorless, nonflammable gas formed during decomposition, combustion and respiration. CO is used in food refrigeration (dry ice), carbonated beverages, fire extinguishers and aerosol cans. Whenever something burns -- such as gasoline, wood or a candle -- CO is produced from the available oxygen combined with the carbon in the fuel.
a colorless, odorless, incombustible gas, somewhat heavier than air that is a product of respiration and combustion.
Carbon dioxide is the main greenhouse gas created by combustion, the so-called greenhouse effect, emitted primarily from human activity such as burning of fossil fuels to generate electricity and vehicles. Scientists believe these greenhouse gases are causing the earth's climate to change.
A greenhouse gas that can be produced as a by-product of oil and gas production, burning fossil fuels and biomass.
A colourless, odourless, incombustible gas formed during normal human breathing. It is also emitted by the combustion activities used to produce electricity, as well as other natural and manmade processes. CO2 is a major cause of the greenhouse effect that traps harmful radiant energy close to the earth's surface.
a gas produced by the combustion of fossil fuels and other substances. CO also occurs naturally in large amounts in molten magma, which is involved in the explosive eruption of volcanoes. See Greenhouse Effect.
