      None of the above

    • E.

      None of the above

    Correct Answer
    A. Reactants
    Explanation
     Reactants are the substances that enter a chemical reaction. They are the starting materials that undergo a chemical change to form new substances called products. Reactants are consumed during the reaction and are usually written on the left side of a chemical equation. In contrast, products are substances that are formed as a result of the reaction and are written on the right side of the equation. Catalysts are substances that speed up the reaction but are not consumed in the process.

    The substances that are the result of a chemical reaction are called ___________. 

    • A.

      Reactants

    • B.

      Products

    • C.

      Catalysts

    • D.

      None of the above

    Correct Answer
    B. Products
    Explanation
    In a chemical reaction, reactants undergo a transformation to form new substances known as products. These products are the end result of the reaction and can have different properties than the reactants. Reactants are the starting materials that participate in the reaction, while catalysts are substances that speed up the reaction without being consumed themselves.

  • 3. 

    A substance that is used to speed up a chemical reaction but is not used as part of the reaction is called a __________. 

    • A.

      Reactant

    • B.

      Product

    • C.

      Catalyst

    • D.

      None of the above

    Correct Answer
    C. Catalyst
    Explanation
    A catalyst is a substance that is used to speed up a chemical reaction without being consumed or permanently changed in the process. It works by providing an alternative pathway for the reaction to occur with lower activation energy, allowing the reaction to proceed more quickly. Unlike reactants and products, which are directly involved in the reaction and are consumed or produced, a catalyst remains unchanged and can be used again in subsequent reactions.

      A combination of the properties of the reactants

    • D.

      None of the above

    Correct Answer
    B. Different than the properties of the reactants
    Explanation
    After a chemical reaction, the properties of the products are different than the properties of the reactants. This is because during a chemical reaction, new substances are formed with different chemical and physical properties compared to the starting materials. The reaction involves the rearrangement of atoms and the formation of new chemical bonds, leading to a change in the properties of the substances involved.

    • A.

      Gas

    • B.

      Liquid

    • C.

      Chunky substance

    • D.

      Solid

    Correct Answer
    D. Solid
    Explanation
    A precipitate is a solid substance formed from a chemical reaction in a liquid solution. It occurs when the reactants in solution combine to form an insoluble solid, which then settles out of the solution. Precipitates can vary in size and appearance, ranging from fine particles to chunky substances.

    Rate this question:

  • 6. 

    The part of the atom involved in chemical bonding is the ____________. 

    • A.

      Nucleus

    • B.

      Valence electrons

    • C.

      Protons

    • D.

      None of the above

    Correct Answer
    B. Valence electrons
    Explanation
    Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding. These electrons determine the atom's reactivity and ability to form chemical bonds with other atoms. The nucleus, which contains protons and neutrons, does not directly participate in chemical bonding. 

    Rate this question:

  • 7. 

    An atom is considered to be ____________ when the number of protons and electrons are equal.

    • A.

      Positive

    • B.

      Negative

    • C.

      Neutral

    • D.

      None of the above

    Correct Answer
    C. Neutral
    Explanation
    An atom is considered to be neutral when the number of protons and electrons are equal. In an atom, protons have a positive charge, while electrons have a negative charge. The positive charge of the protons is balanced out by the negative charge of the electrons, resulting in a neutral overall charge for the atom.

    A chemical reaction where energy is released is called:

    • A.

      Endothermic

    • B.

      Exothermic

    • C.

      Combination reaction

    • D.

      Displacement reaction

    Correct Answer
    B. Exothermic
    Explanation
    An exothermic reaction is a type of chemical reaction in which energy is released in the form of heat or light. This means that the products of the reaction have less energy than the reactants, resulting in a net release of energy. Examples of exothermic reactions include combustion reactions, where a fuel reacts with oxygen to produce heat and light, and many types of oxidation reactions.

    Rate this question:

  • 9. 

    A chemical reaction in which energy is absorbed is called _________.  

    • A.

      Endothermic

    • B.

      Exothermic

    • C.

      Displacement reaction

    • D.

      Decomposition reaction

    Correct Answer
    A. Endothermic
    Explanation
    An endothermic reaction is a chemical reaction that absorbs energy from its surroundings. This means that the reaction requires an input of energy in order to proceed. In an endothermic reaction, the products have a higher energy level than the reactants, and the excess energy is absorbed from the surroundings. This is in contrast to an exothermic reaction, which releases energy to the surroundings.

    Rate this question:

  • 10. 

    A bond where electrons are transferred is called a/an _____________. 

    • A.

      Covalent bond

    • B.

      Ionic bond

    • C.

      Transfer bond

    • D.

      None of the above

    Correct Answer
    B. Ionic bond
    Explanation
    An ionic bond is formed when electrons are transferred from one atom to another. In this type of bond, one atom gains electrons to become negatively charged (anion) while the other atom loses electrons to become positively charged (cation). The attraction between these opposite charges holds the atoms together, forming the ionic bond. Covalent bonds, on the other hand, involve the sharing of electrons between atoms.

  • 11. 

    A bond that occurs between metals and nonmetals is called a/an _______________.

    • A.

      Ionic bond

    • B.

      Covalent bond

    • C.

      Metal bond

    • D.

      None of the above

    Correct Answer
    A. Ionic bond
    Explanation
    An ionic bond is a type of chemical bond that occurs between metals and nonmetals. In this type of bond, electrons are transferred from the metal atom to the nonmetal atom, resulting in the formation of positive and negative ions. The opposite charges of the ions attract each other, creating a strong bond. This bond is characterized by the electrostatic attraction between the oppositely charged ions.

    Rate this question:

  • 12. 

    A bond that occurs between nonmetals and nonmetals is called a/an _________. 

    • A.

      Ionic bond

    • B.

      Covalent bond

    • C.

      Nonmetal bond

    • D.

      None of the above

    Correct Answer
    B. Covalent bond
    Explanation
    A covalent bond occurs between nonmetals and nonmetals when they share electrons. In this type of bond, the atoms involved have similar electronegativities, which means they have a similar ability to attract electrons. As a result, they share electrons to achieve a stable electron configuration. This sharing of electrons creates a strong bond between the atoms, forming a molecule. 

    Rate this question:

  • 13. 

    A bond where electrons are shared is called a/an ______________. 

    • A.

      Ionic bond

    • B.

      Covalent bond

    • C.

      Shared bond

    • D.

      None of the above

    Correct Answer
    B. Covalent bond
    Explanation
    A covalent bond is formed when electrons are shared between two atoms. In this type of bond, both atoms contribute electrons to form a shared electron pair. This sharing of electrons allows both atoms to achieve a more stable electron configuration. Covalent bonds are typically found between nonmetal atoms and result in the formation of molecules. Ionic bonds, on the other hand, involve the transfer of electrons from one atom to another, resulting in the formation of ions.
