Linked from

The 149 pages that link to Carbon dioxide, each with the reason it gives.

• Greenhouse gas emissionsBroader topic: It is the largest contributor to human-caused greenhouse gas emissions.

• Greenhouse effectBroader topic: Its infrared-active vibrations make it a major contributor to the modern greenhouse effect.

• Dipole momentBroader topic: Its polar C=O bond contributions cancel, leaving zero net dipole moment.

• Volcanic gasBroader topic: It can escape from magma at depth and collect in low-lying areas.

• SublimationBroader topic: At atmospheric pressure, its solid form sublimes rather than melting.

• Greenhouse gasBroader topic: It is the largest human-caused contributor to long-term greenhouse-gas forcing.

• CarbonationBroader topic: This is the gas dissolved during carbonation and released as bubbles.

• Baking powderBroader topic: This is the gas whose bubbles expand and help raise the batter.

• MoleculeBroader topic: Its linear structure contrasts with water despite both molecules having three atoms.

• Molecular polarityBroader topic: Its polar carbon–oxygen bonds cancel because they point in opposite directions.

• Joseph BlackBroader topic: Black identified this gas as distinct from ordinary air and called it fixed air.

• Keeling CurveBroader topic: This is the atmospheric constituent whose concentration the curve records.

• Ammonium bicarbonateBroader topic: Its release creates gas bubbles that help dough expand.

• Atmospheric absorptionBroader topic: Its infrared absorption bands strongly influence Earth’s outgoing thermal radiation.

• Carbonated waterBroader topic: This is the gas dissolved in water to create carbonation.

• Charles David KeelingBroader topic: It was the atmospheric constituent Keeling measured.

• Air–sea gas exchangeBroader topic: Its exchange with seawater strongly influences atmospheric carbon and ocean acidity.

• Law of multiple proportionsBroader topic: Its composition can be compared with carbon monoxide to illustrate the law.

• Acid anhydrideBroader topic: Its reactions with water and bases illustrate acid-anhydride behavior.

• Eunice Newton FooteBroader topic: It was the gas that produced the strongest heating in Foote’s experiments.

• Sparkling wineBroader topic: Its dissolution in wine supplies the gas released as bubbles.

• Linear molecular geometryBroader topic: Its O=C=O arrangement is a familiar example of a linear molecule.

• Inorganic compoundBroader topic: It contains carbon but is conventionally classified as inorganic.

• Rotational–vibrational spectroscopyBroader topic: Its bending and asymmetric-stretch bands illustrate symmetry-dependent infrared activity.

• Interstellar iceBroader topic: CO₂ is a common ice constituent produced partly by reactions on grain surfaces.

• Inorganic chemicalsBroader topic: This carbon-containing compound is conventionally classified as inorganic.

• Jan Baptist van HelmontBroader topic: He identified the gas arising from burning charcoal and fermenting materials as a distinct substance.

• Kipp's apparatusBroader topic: Acid reacting with marble chips is a common demonstration of gas generation in the apparatus.
