Question 1

For a galvanic cell that uses the following two half-reactions,

Cr2O72-(aq) + 14 H+(aq) + 6 e- → 2 Cr3+(aq) + 7 H2O(l)
Pb(s) → Pb2+(aq) + 2 e-

how many moles of Pb(s) are oxidized by one mole of Cr2O72-?
◦ 6
◦ 3
◦ 1
◦ 2

Question 2

What is the reduction half-reaction for the following overall cell reaction?

Pb2+(aq) + 2 Ag(s) → Pb(s) + 2 Ag+(aq)


◦ Ag+(aq) + e- → Ag(s)
◦ Pb2+(aq) + 2 e- → Pb(s)
◦ Ag(s) + e- → Ag+(aq)
◦ Pb2+(aq) + e- → Pb(s)

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
