The reaction of Zn and Cu2+ produces a brown solid

DISCUSSION1. The reaction of Zn and Cu2+ produces a brown solid product. What is the identity of this product?Provide the balanced equation that shows the formation of this brown product? (2 points)2. The reaction of Mg with H+ produces vigorous bubbling. Why do bubbles form during thereaction? Write a balanced equation that shows the identity of the product causing bubbles. (2points)3. Activity is more useful when quantitative experiments are done, but is relevant here. Explainwhat activity is and how the use of the same anion throughout all solutions is consistent with thenotion of activity. You might find it useful to consult a textbook for a complete discussion ofactivity. (3 points)4. Many biological reactions are electron transfer reactions and their spontaneity can be determinedby calculating the potential and ΔG of the reaction. For the following reaction, determine a) theoxidizing agent and reducing agent, b) ΔG°, and c) if the reaction is spontaneous. (You will needto use a standard reduction table to determine the E° of the half reaction of O2.) (6 points)NAD+ + 2H+ + 2 e-! NADH + H+ E° = -0.32 VNADH + H+ + ½ O2 ! NAD++ H2O5. What is the empirical “rule” that you can use to determine whether or not a redox reaction will bespontaneous? (Think in terms of the reduction potentials of the oxidizing and reducing agents.)(3 points)
