(a)
Expert Solution
Answer to Problem 1QP
The difference between oxidation and reduction electrochemical reactions is explained as below:
Explanation of Solution
Electrochemical reaction is the process that involves electron transfer between two substances mostly a metal and an electrolyte. It includes oxidation and reduction reactions that occur simultaneously. Oxidation reaction involves loss of electrons by a molecule or an atom to form a cation. This causes increase in oxidation state. Reduction reaction involves gain of electrons by an atom to form an anion. This causes decrease in oxidation state. Thus, the basic difference between oxidation and reduction electrochemical reaction involve loss and gain of electrons in an atom, respectively.
(b)
To determine
To explain:
Which reaction (oxidation and reduction) occurs at anode and which at the cathode?
(b)
Expert Solution
Answer to Problem 1QP
The reaction (oxidation and reduction) occurs at anode and at the cathode is explained as below.
Explanation of Solution
Oxidation and reduction reactions occur at electrodes. Anode refers to negative electrode and cathode refers to positive electrode. Oxidation takes place at the anode as it involves loss of electrons. Reduction takes place at the cathode as it involves gain of electrons.

Response
Response A
Response B
The Lizzie McGuire Movie is a 2003 film that serves as a sequel to the Disney Channel series, Lizzie McGuire, about a young girl navigating her early teen years with her family and three best friends, Miranda (played by Hilary Duff) and Gordo (played by Adam Sandler). In the film, the three friends travel to Rome with their classmates after graduating junior high. Lizzie discovers that she is the spitting image of an Italian pop star, and is asked to take her place on stage at the International Music Video Awards alongside the pop star’s handsome ex, Paolo. Meanwhile, Gordo must decide whether to confess his feelings for Lizzie, or allow her to live out a pop star fantasy with Paolo. The film stars Hilary Duff as Lizzie, as well as…
