Because of its mobility in groundwater, its toxicity at low levels, and its density (which causes it to sink below the water table), cleanup activities are more difficult than for oil spills: oil has a specific gravity less than 1. Tetrachloroethylene is a colourless, non‐flammable liquid (molar mass 165.83 g/mol, density 1.62 g/cm 3, melting point –22 °C, boiling point 121 °C).

Exposure to very high concentrations of tetrachloroethylene can cause dizziness, headaches, sleepiness, confusion, nausea, difficulty in speaking and walking, unconsciousness, and death. ; Lelieveld, J., Comprehensive two-dimensional gas chromatography (GC*GC) measurements of volatile organic compounds in the atmosphere, Atmos. Lines are drawn between atoms to indicate chemical bonds. To write Lewis dot structure I think you can get that but one hint is to put a double bond between the carbons. A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. At each end, the chlorine atoms are spaced approximately 120 degrees from each other and from the carbon atom. CopyCopied, CYTYCFOTNPOANT-UHFFFAOYSA-N A, 993, 2003, 187-195. ass: Semi-standard non-polar; Column diameter: 0.32 mm; Column length: 60 m; Column type: Capillary; Heat rate: 4 K/min; Start T: 60 C; End T: 180 C; Start time: 2.8 min; CAS no: 127184; Active phase: DB-5; Carrier gas: He; Phase thickness: 1 um; Data type: Linear RI; Authors: Harangi, J., Short communication. With a specific gravity greater than 1, tetrachloroethylene will be present as a dense nonaqueous phase liquid (DNAPL) if sufficient quantities are released. In Europe, the Scientific Committee on Occupational Exposure Limits (SCOEL) recommends for tetrachloroethylene an occupational exposure limit (8 hour time-weighted average) of 20 ppm and a short-term exposure limit (15 min) of 40 ppm.[22].
