Answer:

At normal temperature and pressure, hydrogen chloride (HCl) is a gas made up of the elements hydrogen and chlorine. The HCL does not contain carbon.

Explanation:

  • Hydrochloric acid (HCl) is a colorless, highly corrosive liquid that is classified as a strong mineral acid.
  • Pickling steel, acid treatment for oil wells, chemical cleaning, and chemical processing for large-scale manufacturing of vinyl chloride are the most common uses for HCl.

Explanation for incorrect answers:

a) DNA:

  • A sugar, phosphate group, and base make comprise a single basic unit or "building block" of DNA.
  • Sugars are carbon and oxygen atom rings. Deoxy-ribose is the sugar in DNA that has five carbon atoms (hence the "Deoxy-ribo" in DNA).

b) Plastic:

  • Organic polymers are found in almost all plastics.
  • The great majority of these polymers are made up of carbon chains with or without oxygen, nitrogen, or Sulphur atoms attached.

d) Diesel:

  • Paraffins, aromatics, and naphthene make up the majority of diesel fuel.
  • The hydrocarbons in gasoline typically contain 4-12 carbon atoms and boil between 30 and 210 °C, whereas the hydrocarbons in diesel fuel typically contain 12–20 carbon atoms and boil between 170 and 360 °C.
