Question 1

Of Sn2+, Ag+, and/or Zn2+, which could be reduced by Cu?

◦ Sn2+

◦ Ag+

◦ Zn2+

◦ Two of them could be reduced by Cu.
◦ All of them could be reduced by Cu.

Question 2

Refer to the galvanic cell below (the contents of each half-cell are written beneath each compartment):

0.10 M MnO4–                           0.40 M Cr3+
0.20 M Mn2+                             0.30 M Cr2O72–
0.010 M H+                              0.010 M H+
The standard reduction potentials are as follows:
MnO4– + 8H+ + 5e–→ Mn2+ + 4H2O, E° = 1.51 V
Cr2O72– + 14H+ + 6e–→ 2Cr3+ + 7H2O, E° = 1.33 V

When current is allowed to flow, which species is oxidized?

​

Reference: 18-3

​

​


◦ Cr2O72–
◦ Cr3+
◦ MnO4–
◦ Mn2+
◦ H+

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.
