Questions and Answers
  • 1. 

    What is the smallest chemical unit of matter?

    • A.

      Molecule

    • B.

      Atom

    • C.

      Solution

    • D.

      Concentration

    Correct Answer
    B. Atom
    Explanation
    An atom is the smallest chemical unit of matter. It consists of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus. Atoms combine together to form molecules, which are groups of atoms bonded together. A molecule is a larger unit of matter compared to an atom. A solution is a mixture of two or more substances, and concentration refers to the amount of solute present in a given amount of solvent. Neither of these options represents the smallest unit of matter, which is an atom.

    What are two or more atoms linked together to make a substance with unique properties?

    • A.

      Molecule

    • B.

      Atom

    • C.

      Solution

    • D.

      Concentration

    Correct Answer
    A. Molecule
    Explanation
    A molecule is formed when two or more atoms are chemically bonded together. These atoms can be of the same element or different elements. The unique arrangement and combination of atoms in a molecule give it distinctive properties that are different from the individual atoms. Therefore, a molecule is a substance with unique properties due to the specific arrangement of its constituent atoms.

    What is the quantity of a substance within a certain volume?

    • A.

      Atom

    • B.

      Molecule

    • C.

      Solution

    • D.

      Concentration

    Correct Answer
    D. Concentration
    Explanation
    Concentration refers to the amount of a substance present within a specific volume. It is a measure of how much solute is dissolved in a solvent or how much of a particular component is present in a mixture. In other words, concentration tells us the relative abundance or strength of a substance in a given volume.

    Sulfur is a yellow powder that is composed of sulfur atoms.  Sulfur dioxide is a colorles, poisonous gas that contains sulfur atoms.  Is sulfur dioxide composd of atoms or molecules?

    • A.

      Atoms

    • B.

      Molecules

    Correct Answer
    B. Molecules
    Explanation
    Sulfur dioxide is composed of molecules. In the given question, it is mentioned that sulfur dioxide is a gas that contains sulfur atoms. Since atoms combine to form molecules, it can be inferred that sulfur dioxide is composed of molecules.

    How many centimeters are in 1.6 meters?

    • A.

      0.16 cm

    • B.

      1.6 cm

    • C.

      160 cm

    • D.

      1600 cm

    Correct Answer
    C. 160 cm
    Explanation
    There are 100 centimeters in 1 meter. Therefore, to find the number of centimeters in 1.6 meters, we multiply 1.6 by 100. This gives us 160 centimeters.

    An object's volume is 0.12 kL.  What is its volume in liters?

    • A.

      0.12 L

    • B.

      1.2 L

    • C.

      12 L

    • D.

      120 L

    Correct Answer
    D. 120 L
    Explanation
    The correct answer is 120 L because 0.12 kL is equal to 120 L. The prefix "kilo" represents a factor of 1000, so 0.12 kL is equivalent to 0.12 multiplied by 1000, which equals 120. Therefore, the object's volume is 120 liters.

    A rock has a mass of 45.1 kg.  What is its mass in slugs?  (1 slug = 14.49 kg)  Round to the nearest whole number.

    • A.

      3 kg

    • B.

      15 kg

    • C.

      45 kg

    • D.

      675 kg

    Correct Answer
    A. 3 kg
    Explanation
    The correct answer is 3 kg. To convert the mass of the rock from kilograms to slugs, we divide the mass in kilograms by the conversion factor of 14.49 kg/slug. Therefore, 45.1 kg ÷ 14.49 kg/slug = 3.11 slugs. Since we are asked to round to the nearest whole number, the mass of the rock in slugs is 3 slugs.
