Question 1

Consider an electrochemical cell with a zinc electrode immersed in 1.0 M Zn2+ and a silver electrode immersed in 1.0 M Ag+.

    Zn2+ + 2e–→ Zn        E° = –0.758 V

    Ag+ + e–→ Ag          E° = 0.800 V

Calculate E° for this cell.


◦ 0.042 V
◦ –0.042 V
◦ 1.558 V
◦ –1.558 V
◦ None of these are correct.

Question 2

Consider an electrochemical cell with a zinc electrode immersed in 1.0 M Zn2+ and a nickel electrode immersed in 0.10 M Ni2+.
Zn2+ + 2e-→ Zn
E° = –0.76 V
Ni2+ + 2e-→ Ni
E° = –0.23 V
  

 Calculate the concentration of Ni2+if the cell is allowed to run to equilibrium at 25°C.

​

Reference: Ref 18-4

​

​


◦ 1.10 M
◦ 0.20 M
◦ 0.10 M
◦ 0 M
◦ None of these are correct.

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Looking at the sun may not only cause headache and distort your vision temporarily, but it can also cause permanent eye damage. Any exposure to sunlight adds to the cumulative effects of ultraviolet (UV) radiation on your eyes. UV exposure has been linked to eye disorders such as macular degeneration, solar retinitis, and corneal dystrophies.
