| hydronium ion | |
| Cobalt | A trace element that is a component of vitamin B12. It has the atomic symbol Co, atomic number 27, and atomic weight 58.93. It is used in nuclear weapons, alloys, and pigments. Deficiency in animals leads to anemia; its excess in humans can lead to erythrocytosis. |
| chlorine | An element with atomic symbol Cl, atomic number 17, and atomic weight 35, and member of the halogen family. |
| iodoethane | structure in first source |
| 1,2-dichloroethylene, (Z)-isomer | |
| trichloroethylene | A highly volatile inhalation anesthetic used mainly in short surgical procedures where light anesthesia with good analgesia is required. It is also used as an industrial solvent. Prolonged exposure to high concentrations of the vapor can lead to cardiotoxicity and neurological impairment. |
| nitrous oxide | Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream. |
| propyl iodide | |
| cobamamide | |
| sulfites | Inorganic salts of sulfurous acid. |
| ethylene | |
| vinyl chloride | A gas that has been used as an aerosol propellant and is the starting material for polyvinyl resins. Toxicity studies have shown various adverse effects, particularly the occurrence of liver neoplasms. |
| tetrachloroethylene | A chlorinated hydrocarbon used as an industrial solvent and cooling liquid in electrical transformers. It is a potential carcinogen. |
