Question 1

What is undergoing reduction in the redox reaction represented by the following cell notation?

Pb(s) ∣ Pb2+(aq) H+(aq) ∣ H2(g) ∣ Pt(s)

◦ Pt(s)
◦ Pb2+(aq)
◦ H+(aq)
◦ H2(g)
◦ Pb(s)

Question 2

Which of the following is TRUE about standard electrode potentials?
◦ E°cell is negative for spontaneous reactions.
◦ The electrode potential of the standard hydrogen electrode is exactly zero.
◦ Electrons will flow from a more positive electrode to a more negative electrode.
◦ The electrode in any half-cell with a greater tendency to undergo reduction is negatively charged relative to the standard hydrogen electrode and therefore has E° < 0.
◦ E°cell is the sum between standard reduction potentials of the anode and the cathode.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Did you know?

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.

Signs of depression include feeling sad most of the time for 2 weeks or longer; loss of interest in things normally enjoyed; lack of energy; sleep and appetite disturbances; weight changes; feelings of hopelessness, helplessness, or worthlessness; an inability to make decisions; and thoughts of death and suicide.

Glaucoma is a leading cause of blindness. As of yet, there is no cure. Everyone is at risk, and there may be no warning signs. It is six to eight times more common in African Americans than in whites. The best and most effective way to detect glaucoma is to receive a dilated eye examination.
