  1. B) exothermic

    Explanation:

    Endothermic: The chemical reactions in which reactants form products by absorption of energy are called as endothermic reactions.

    Exothermic : The chemical reactions in which reactants form products along with release of energy are called as exothermic reactions. Thus if walls turn hot that means the energy has been released.

    Reversible: The chemical reactions in which reactants form products and products can also be converted back to reactants are called as reversible reactions.

    Irreversible: The chemical reactions in which reactants form products but products can not be converted back to reactants are called as irreversible reactions.

  2. Deshydrohalogenation

    Explanation:

    You are not providing options to answer, however, this can be answered without options.

    Now, in the reaction we can see that we have an atom of Bromine in carbon 2, and in the product appears as NaBr. This means that the Br was substracted by elimination. It's an elimination because the final product do not have a substituent where the bromine was, (Like another nucleophyle such OH or another halide). If you look closely the final product, we can see that one hydrogen in carbon 3, is no longer there. So this electrophyle was also substracted, in this case, by a base (Such NaOH), so in this case, it's ocurring an elimination reaction via E2 (One step, bimolecular). So, as the final product has been substracted the nucleophyle and electrophyle, this treaction is a deshydrohalogenation (an atom of hydrogen and a halide were substracted). The mechanism of this, you can see it in the picture.

  3. Which of the following types of reactions would decrease the entropy within a cell?

    Answer is : Option A : anabolic reactions

    The general meaning of entropy can be termed as the systems that naturally progress from order to disorder. Anabolic reactions contains all the metabolic processes that build bio-molecules.

  4. The given reaction is the generic reaction for synthesis reaction.

    Explanation:

    For the given options:

    Option A: Single displacement reaction

    Single displacement reaction is defined as the reaction in which more reactive element displaces the less reactive element fro its chemical reaction.

    [tex]A+BC\rightarrow AC+B[/tex]

    Option B: Double-displacement reaction

    Double-displacement reaction is defined as the reaction in which exchange of ions takes place.

    [tex]AB+CD\rightarrow AD+CB[/tex]

    Option C: Synthesis

    Synthesis reaction is defined as the reaction in which two substances combine in their elemental state to form one single product

    [tex]A+B\rightarrow AB[/tex]

    Option D: Decomposition

    Decomposition reaction is defined as the chemical reaction in which a large substance breaks down into two or more small substances

    [tex]AB\rightarrow A+B[/tex]

    Hence, the given reaction is the generic reaction for synthesis reaction.

  5. The correct answer for 1 is Option 4 and for 2 is Option 1.

    Explanation:

    For 1:

    From the given options:

    Decomposition reaction is defined as the reaction in which a compound breaks down into two or more smaller compounds.

    Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance is increased.

    Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.

    Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

    From the above information, the correct answer is Option 4.

    For 2:

    Reducing agent is defined as the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction.

    Oxidizing agent is defined as the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction.

    The reaction of sodium and oxygen follows the equation:

    [tex]4Na(s)+O_2(g)\rightarrow 2Na_2O(s)[/tex]

    On reactant side:

    Oxidation state of sodium = 0

    Oxidation state of oxygen = 0

    On product side:

    Oxidation state of sodium = +1

    Oxidation state of oxygen = -2

    As, the oxidation state of sodium is increasing from 0 to +1, it is undergoing an oxidation reaction and thus is a reducing agent. While the oxidation state of oxygen is reducing from 0 to -2, it is undergoing an reduction reaction and thus is a oxidizing agent.

    Hence, the correct answer is Option 1.

  6. Which of the following types of reactions would decrease the entropy within a cell?

    Answer is : Option A : anabolic reactions

    The general meaning of entropy can be termed as the systems that naturally progress from order to disorder. Anabolic reactions contains all the metabolic processes that build bio-molecules.

  7. The correct answer is Option B.

    Explanation:

    Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.

    [tex]AB\rightarrow A+B[/tex]

    Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.

    [tex]AB+CD\rightarrow AD+CB[/tex]

    Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.

    [tex]A+B\rightarrow AB[/tex]

    Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.

    [tex]A+BC\rightarrow AC+B[/tex]

    In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has [tex]CaCO_[/tex] as a component.

    The reaction between HCl and [tex]CaCO_3[/tex]is a type of neutralization reaction and it is a type of double displacement reaction.

    The equation between the two follows:

    [tex]CaCO_3+HCl\rightarrow CaCl_2+H_2O+CO_2[/tex]

    Hence, the correct answer is Option B.

  8. I am taking the same test 😉

    1.)Single-displacement  

    AB + C --> AC + B  

    2.)Double-displacement

    AB + CD --> AD + CB

    3.)Synthesis

    A + B --> AB

    4.)Decomposition

    AB --> A + B

    Hope this helps!
