About This Quiz


Do you know how to classify matter? Matter on Earth usually occurs in three states: solid, liquid, and gas. Tightly packed particles compose solid matter, and a solid will retain its shape, whereas loosely packed particles make up liquid matter, adopting the form of its container. Gaseous matter usually does not have a defined shape or volume. Test your understanding of the classification of substances and discover how different materials are categorized in the realm of chemistry. Whether you're a student aiming to reinforce your knowledge or a science enthusiast curious about the building blocks of our world, this quiz offers an engaging way to explore the classification of matter. Uncover the principles that govern the composition of substances and enhance your understanding of the diverse forms matter can take. Embark on this educational journey and enrich your knowledge of the basic principles that govern the physical world.

  • 2. 

    Gold is a(n) 

    • Mixture

    • Compound

    • Element

    • None

    Correct Answer
    A. Element
    Explanation
    Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable, and ductile metal. Gold is a pure substance that cannot be broken down into simpler substances by chemical means.

    Is Mercury an element, compound, or mixture? 

    • Element

    • Compound

    • Mixture

    • None

    Correct Answer
    A. Element
    Explanation
    Mercury is an element because it cannot be broken down into simpler substances through chemical reactions. It is a unique and pure substance made up of only one type of atom, specifically mercury atoms. Elements are the building blocks of all matter, and there are 118 known elements on the periodic table.

    Rate this question:

  • 4. 

    Vegetable soup is a

    • Compound

    • Element

    • Homogeneous mixture

    • Heterogeneous mixture

    Correct Answer
    A. Heterogeneous mixture
    Explanation
    A vegetable soup is considered a heterogeneous mixture because it is made up of multiple different components that are not evenly distributed throughout the mixture. In vegetable soup, there are various vegetables, spices, and broth that are all combined together. These components can be seen and distinguished from one another, and they do not blend together to form a uniform composition.

  • 5. 

    Carbon dioxide is a 

    • Element

    • Compound

    • Mixture

    • All of these

    Correct Answer
    A. Compound
    Explanation
    Carbon dioxide is a compound because it is composed of two different elements, carbon and oxygen, chemically bonded together. A compound is a substance made up of two or more elements that are chemically combined in a fixed ratio. In the case of carbon dioxide, one carbon atom is bonded to two oxygen atoms, forming a stable compound with specific properties.

    Rate this question:

  • 6. 

    Water can boil at 100 degrees Celsius. What type of change occurs when water reaches this temperature?

    • A chemical change

    • A physical change

    • Both

    • None

    Correct Answer
    A. A physical change
    Explanation
    Boiling water at 100 degrees Celsius is a physical change because it involves a change in the state of matter from liquid to gas, without altering the chemical composition of the water molecules. The temperature increase causes the water molecules to gain enough energy to overcome the intermolecular forces and transform from a liquid  a gaseous state. This change is reversible, as the water can be cooled down to return to its liquid state without any chemical reactions occurring.

    Rate this question:

  • 7. 

    Is table salt,  also known as sodium chloride, an element, a compound, or a mixture? 

    • Element

    • Compound

    • Mixture

    • A & B

    Correct Answer
    A. Compound
    Explanation
    Table salt, also known as sodium chloride, is a compound. A compound is a substance composed of two or more elements chemically bonded together. Table salt is made up of sodium (Na) and chloride (Cl) ions that are held together by ionic bonds. This means that sodium chloride has a fixed ratio of sodium to chloride atoms, giving it a distinct chemical composition.

    Rate this question:

  • 8. 

    What type of a mixture is coffee? 

    • A homogeneous mixture

    • A heterogeneous mixture

    • Both

    • None

    Correct Answer
    A. A homogeneous mixture
    Explanation
    Coffee is a homogeneous mixture because it is made up of different substances that are uniformly distributed throughout. When coffee is brewed, the water, coffee beans, and any other additives such as sugar or milk, combine to form a single phase. This means that no matter where you sample the coffee from, it will have the same composition and properties. There are no visible differences or separate phases within the mixture, making it homogeneous.

    Rate this question:

  • 9. 

    Which of the following is NOT a pure substance?

    • Gold 

    • Water 

    • Saltwater 

    • Diamond

    Correct Answer
    A. Saltwater 
    Explanation
    A pure substance has a fixed and uniform composition. Gold, water, and diamond are all pure substances with specific chemical compositions. Saltwater is a mixture of salt and water, meaning its composition can vary, making it not a pure substance.

    Rate this question:

  • 10. 

    Tap water is a ____ mixture. 

    • Homogeneous

    • Heterogeneous

    • Both

    • None

    Correct Answer
    A. Homogeneous
    Explanation
    Tap water is a homogeneous mixture because it is composed of multiple substances (such as minerals, dissolved gases, and impurities) that are uniformly distributed throughout the water. This means that the composition of tap water is similar throughout, regardless of where it is sampled from.
