    The Law of Conservation of Mass is the law that states matter is destroyed or created in any physical change or chemical reaction.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The explanation for the given correct answer is that the Law of Conservation of Mass states that matter is neither created nor destroyed in any physical change or chemical reaction. This means that the total mass of the substances involved in a reaction remains constant before and after the reaction. Therefore, the statement that matter is destroyed or created in any physical change or chemical reaction is incorrect.

    One or two letter representation of can element is:

    • Physical symbol

    • Chemical chain

    • Chemical symbol

    Correct Answer
    A. Chemical symbol
    Explanation
    The correct answer is "chemical symbol" because a chemical symbol is a one or two letter representation of an element. It is a shorthand way to represent elements in the periodic table and is used to identify and differentiate between different elements.

    What word means: a change during which some properties of a material change, but the composition does not change

    • Chemical change

    • Product

    • Physical change

    Correct Answer
    A. Physical change
    Explanation
    A physical change refers to a transformation in the properties of a material without any alteration in its composition. This means that although the material may undergo a change in its physical state, shape, size, or appearance, the chemical composition remains the same. In contrast, a chemical change involves a modification in the chemical composition of the substance, resulting in the formation of new substances with different properties. Therefore, the term "physical change" accurately describes a change where only the physical characteristics of a material are altered.

    A change in which one or more of the reactants change into or more products; characterized by the breaking of bonds in the reactants and the formation of bonds in the product is:

    • Chemical reaction

    • Product

    • Reactant

    Correct Answer
    A. Chemical reaction
    Explanation
    A chemical reaction refers to a process where one or more reactants undergo a transformation to form one or more products. This transformation involves the breaking of bonds in the reactants and the formation of new bonds in the products. It is a fundamental concept in chemistry that describes the rearrangement of atoms and the conversion of substances into different substances.

    A ________________ is a substance present at the start of a chemical reaction

    Correct Answer
    reactant
    Explanation
    A reactant is a substance that is present at the beginning of a chemical reaction and undergoes a chemical change. It is the starting material that is consumed during the reaction to produce new substances called products. Reactants are typically written on the left side of a chemical equation, indicating their presence before the reaction takes place. They are essential for initiating and driving the reaction forward by providing the necessary atoms or molecules to form new bonds and create the desired products.

    Rate this question:

  • 7. 

    A product is a substance _____________ in a chemical reaction.

    Correct Answer
    produced
    Explanation
    A product is a substance that is formed or generated as a result of a chemical reaction. It is the outcome or end result of the reaction, indicating that it has been produced or created. In the context of chemical reactions, products are the new substances that are formed from the reactants involved in the reaction.

    Rate this question:

  • 8. 

    Change that produces matter with a different composition than the original matter is:

    • Chemical change

    • Chemical reaction

    • Reactant

    Correct Answer
    A. Chemical reaction
    Explanation
    A chemical reaction refers to a process where one or more substances undergo a transformation, resulting in the formation of new substances with different chemical compositions than the original matter. This change occurs due to the breaking and forming of chemical bonds between atoms, leading to the rearrangement of atoms to create new molecules or compounds. Therefore, a chemical reaction is the correct answer as it accurately describes the change that produces matter with a different composition than the original matter.

    Rate this question:

  • 9. 

    ____________ is a solid that forms and settles out of a liquid mixture

    Correct Answer
    precipitate
    Explanation
    A precipitate is a solid that forms and settles out of a liquid mixture. This occurs when two or more substances in the liquid react chemically and produce an insoluble product. The insoluble product then separates from the liquid and settles at the bottom. This process is commonly observed in various chemical reactions, such as when two clear solutions are mixed and a cloudy or solid substance is formed. The formation of a precipitate is an indication of a chemical change taking place in the liquid mixture.
