Question

In the following reaction, identify the oxidizing and reducing agents. Cl2 + 2NaBr arrow Br2 + 2NaCI Select one: a. Na^+ is the reducing agent, Cl2 is the oxidizing agent b. Br is the reducing agent, Cl2 is the oxidizing agent c. Br^2+ is the reducing agent, Cl2 is the oxidizing agent d. CL^- the oxidizing agent, Br is the reducing agent e. Br^- is the oxidizing agent, Cl2 is the reducing agent Nitrous oxide reacts with chromium (II) ions to form chromium (Ill) ions and hydroxylammonium ion in an acidic aqueous solution. Write the balanced equation for this reaction. Select one: Consider the electrochemical cell diagram shown below. As you observe the reaction in the cell, you notice that the chromium electrode seems to be disappearing while there are deposits forming on the gold electrode. Which of the following is a correct statement? Select one: a. The electrons flow from the gold electrode to the chromium electrode. b. If this cell were used as a battery, the chromium electrode would be marked +. c. Lithium ions are flowing through the salt bridge to the gold solution. d. The half-reaction occurring at the chromium electrode is Cr^2+ + 2^-e arrow Cr.
