    The gain of electrons is...

    • Oxidation

    • Reduction

    Correct Answer
    A. Reduction
    Explanation
    The gain of electrons is referred to as reduction. In a chemical reaction, reduction involves the addition of electrons to a substance, resulting in a decrease in its oxidation state. This process is often associated with the gain of hydrogen atoms or the loss of oxygen atoms. Reduction is a fundamental concept in redox reactions, where one substance is oxidized (loses electrons) while another substance is reduced (gains electrons).

    If an atom becomes more negatively charged, it has been...

    • Oxidized

    • Reduced

    Correct Answer
    A. Reduced
    Explanation
    When an atom becomes more negatively charged, it means that it has gained electrons. This process is known as reduction. Reduction occurs when there is a gain of electrons, which leads to a decrease in the atom's overall positive charge. Therefore, the correct answer is reduced.

    If an atom becomes more positively charged, is has been...

    • Oxidized

    • Reduced

    Correct Answer
    A. Oxidized
    Explanation
    When an atom becomes more positively charged, it means that it has lost electrons. This loss of electrons is known as oxidation. In oxidation, the atom's oxidation state increases, leading to a more positive charge. Therefore, the correct answer is oxidized.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    The given answer is "yes" because redox refers to a type of chemical reaction that involves the transfer of electrons between two species. Since the question is asking if it is redox, the correct answer would be "yes" if the situation or scenario being referred to involves a redox reaction.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    The given question is asking whether something is redox or not. The answer "no" indicates that the thing in question is not a redox process.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    The given answer "yes" suggests that the process or reaction being referred to in the question involves a redox reaction. A redox reaction is a chemical reaction in which there is a transfer of electrons between species, resulting in a change in oxidation states. Since the answer is "yes," it implies that the process being discussed does involve such a transfer of electrons, making it a redox reaction.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    The given answer "yes" suggests that the situation or scenario being referred to involves a redox reaction. This means that there is a transfer of electrons between species, resulting in a change in oxidation states. Without further context or information, it is difficult to provide a more specific explanation.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    The given answer "no" suggests that the situation or scenario being referred to is not a redox reaction. A redox reaction involves the transfer of electrons between species, resulting in a change in their oxidation states. Since the answer is "no," it implies that there is no transfer of electrons occurring in the given situation.

    Is it redox? - ProProfs

    Is it redox?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    The given answer is "no" because redox refers to a chemical reaction that involves the transfer of electrons between species. Since the question does not provide any details about a specific reaction or species involved, it is not possible to determine if it is a redox reaction or not. Therefore, the answer is "no" as it cannot be concluded whether it is redox or not based on the given information.
