Questions and Answers
  • 1. 

    CH3(CH2)16CO2H

    • A.

      Inorganic.

    • B.

      Organic; Amino Acid

    • C.

      Organic; Carbohydrate

    • D.

      Organic; Lipid

    Correct Answer
    D. Organic; Lipid
    Explanation
    The given chemical formula CH3(CH2)16CO2H represents a long carbon chain with a carboxylic acid group at the end. This structure is characteristic of a fatty acid, which is a type of lipid. Lipids are organic compounds that are insoluble in water and are an important component of cell membranes and energy storage in the body. Therefore, the correct answer is "Organic; Lipid".

    • C.

      Organic; Carbohydrate

    • D.

      Organic; Lipid

    Correct Answer
    C. Organic; Carbohydrate
    Explanation
    The given answer "Organic; Carbohydrate" is correct because carbohydrates are organic compounds that consist of carbon, hydrogen, and oxygen atoms. The information provided in the question states that green represents carbon, red represents oxygen, and white represents hydrogen. Since carbohydrates contain all three of these elements, it can be concluded that carbohydrates are organic compounds.

    • D.

      Organic; Lipid

    Correct Answer
    D. Organic; Lipid
    Explanation
    The given answer "Organic; Lipid" is correct because lipids are organic compounds that contain carbon, hydrogen, and oxygen. Lipids are a diverse group of molecules that include fats, oils, waxes, and steroids. They are an essential component of cell membranes, provide energy storage, and play a role in hormone production. The color coding of green for carbon, red for oxygen, and white for hydrogen supports the identification of lipids as the correct answer.

    • D.

      Organic; Lipid

    Correct Answer
    A. Inorganic.
    Explanation
    The correct answer is inorganic because NaCl is the chemical formula for table salt, which is a compound composed of sodium (Na) and chlorine (Cl). Inorganic compounds are those that do not contain carbon and are typically derived from non-living matter. NaCl is a simple inorganic compound that is commonly found in nature and used in various applications, such as seasoning food and preserving food products.
