13) Which of the following statement(s) is/ are correct? I. Oxidizing agent is an agent that causes another species to be oxidized , but itself is reduced. II- During the reduction molecules loss oxygen atom. III- In a galvanic cell spontaneous chemical reaction generate electrical energy. A) Only I B) Only III C) I and III D) II and III E) I, II and III

The correct answer is C) I and III.<br /><br />Explanation:<br /><br />I. Oxidizing agent is an agent that causes another species to be oxidized, but itself is reduced.<br />This statement is correct. An oxidizing agent is a substance that gains electrons and is reduced in a chemical reaction, causing another species to be oxidized.<br /><br />II. During the reduction molecules lose oxygen atom.<br />This statement is incorrect. During the reduction process, molecules gain electrons and typically gain hydrogen atoms, not lose oxygen atoms.<br /><br />III. In a galvanic cell spontaneous chemical reaction generates electrical energy.<br />This statement is correct. In a galvanic cell, a spontaneous chemical reaction occurs, and this reaction generates electrical energy that can be harnessed to do work.<br /><br />Therefore, the correct statements are I and III.
