  • 2. 

    The particles of a solid are packed ___________.

    • Loosely

    • Tightly

    • Packed

    • Separated

    Correct Answer
    A. Tightly
    Explanation
    The particles of a solid are packed tightly. This means that the particles are closely packed together, with very little space between them. This tight packing gives solids their characteristic shape and volume, as the particles are not able to move freely. The strong intermolecular forces between the particles in a solid also contribute to this tight packing arrangement.

    Which of the following is insoluble in water?

    • Lemon juice

    • Oil

    • Sugar

    • Salt

    Correct Answer
    A. Oil
    Explanation
    Oil is insoluble in water because it is a nonpolar substance, while water is a polar substance. Polar substances dissolve in other polar substances, and nonpolar substances dissolve in other nonpolar substances. Since oil and water have different polarities, they do not mix and oil does not dissolve in water.

  • 4. 

    A symbol of calcium _________.

    • Ca

    • C

    • K

    • Cal

    Correct Answer
    A. Ca
    Explanation
    The symbol "Ca" is the chemical symbol for calcium. Chemical symbols are used to represent elements in the periodic table, and "Ca" specifically represents the element calcium.

    Rate this question:

  • 5. 

    Which of the following is not a pure substance?

    • Copper

    • Sugar solution

    • Water

    • Gold

    Correct Answer
    A. Sugar solution
    Explanation
    A pure substance is defined as a substance that is made up of only one type of atom or molecule. Copper, water, and gold are all examples of pure substances because they consist of only one type of element or compound. However, a sugar solution is not a pure substance because it is a mixture of sugar molecules dissolved in water. Therefore, the correct answer is sugar solution.

    Rate this question:

  • 6. 

    What is made up of two or more pure substances which may be in any ratio?

    • Atom

    • Element

    • Mixture

    • Molecule

    Correct Answer
    A. Mixture
    Explanation
    A mixture is made up of two or more pure substances which may be in any ratio. It is a combination of different substances that are physically combined, but not chemically bonded. Unlike elements or molecules, which are specific types of substances, a mixture can vary in composition and properties depending on the amounts and types of substances present. Therefore, a mixture is the correct answer to the question.

    Rate this question:

  • 7. 

    The grouping of materials with having similar properties is called

    • Classification

    • Mixing

    • Dissolution

    • Saturation

    Correct Answer
    A. Classification
    Explanation
    The correct answer is "classification." Classification refers to the act of grouping materials together based on their similar properties. This process helps in organizing and categorizing different materials, making it easier to study and understand them. It allows scientists and researchers to identify patterns and relationships between materials, leading to a better understanding of their behavior and characteristics.

    Rate this question:

  • 8. 

    Pb is the symbol of ___________

    • Lead

    • Magnesium

    • Lead Nitrate

    • Gold

    Correct Answer
    A. Lead
    Explanation
    The correct answer is Lead. Pb is the symbol for lead on the periodic table.

    Rate this question:

  • 9. 

    Water is a/an

    • Element

    • Compound

    • Mixture

    • Pure substance

    • Both B and D

    Correct Answer
    A. Both B and D
    Explanation
    Water is a compound and a pure substance because it is made up of two different elements, hydrogen and oxygen, chemically bonded together. A compound is a substance composed of two or more elements in a fixed ratio. In the case of water, the ratio is always two hydrogen atoms to one oxygen atom, resulting in the chemical formula H2O. This chemical bonding between the elements gives water its unique properties and characteristics.

    Rate this question:

  • 10. 

    What is an example of a compound?

    • Sugar solution

    • Ammonia

    • Hydrogen

    • Sodium

    Correct Answer
    A. Ammonia
    Explanation
    Ammonia is an example of a compound because it is made up of two or more different elements chemically bonded together. It consists of one nitrogen atom and three hydrogen atoms, which are bonded together to form the compound ammonia. In contrast, sugar solution, hydrogen, and sodium are not compounds because they are either pure substances or elements.
