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)

Vital signs (blood pressure, temperature, pulse rate, respiration rate) should be taken before any drug administration. Patients should be informed not to use tobacco or caffeine at least 30 minutes before their appointment.

For high blood pressure (hypertension), a new class of drug, called a vasopeptidase blocker (inhibitor), has been developed. It decreases blood pressure by simultaneously dilating the peripheral arteries and increasing the body's loss of salt.

Did you know?

As many as 20% of Americans have been infected by the fungus known as Histoplasmosis. While most people are asymptomatic or only have slight symptoms, infection can progress to a rapid and potentially fatal superinfection.
