Answer:
Carbon monoxide.
Explanation:
Carbon monoxide is a gas that consists of an oxygen and a carbon to be able to fulfill the complete molecule, it is a potentially dangerous gas for life on this earth.
On the other hand, what differentiates it from carbon dioxide is that it has two oxygens that are coupled with a carbon to fulfill the complete molecule.
Both gases are pollutants, and produced by man, it is considered that these in high partial pressures in the atmosphere generate a mortal potential for humans since they have more affinity with the hemoglobin protein that is the human gas transporter par excellence, the which oxygenates the tissues.
If the oxygen drops in partial pressure and these toxic gases increase, the hemoglobin having a higher affinity will bind to them and toxify the human body, preventing oxygenation.
