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) 1, II and III

Answer 1

The correct answer is C) I and III.Explanation:I- Oxidizing agent is an agent that causes another species to be oxidized but itself is reduced.This statement is correct. An oxidizing agent is a substance that gains electrons and is reduced in a chemical reaction. It causes another species to be oxidized (lose electrons).II- During the reduction molecules lose oxygen atom.This statement is incorrect. During the reduction process, molecules gain electrons, and this often results in the addition of hydrogen atoms or the loss of oxygen atoms, not the loss of oxygen atoms.III- In a galvanic cell spontaneous chemical reaction generates electrical energy.This statement is correct. In a galvanic cell, a spontaneous chemical reaction occurs, and this reaction generates electrical energy. The chemical energy is converted into electrical energy.Therefore, the correct statements are I and III.
