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

In which direction do electrons flow in the external circuit?

Reference: 18-3

​

​


◦ left to right
◦ right to left
◦ no current flows; the cell is at equilibrium
◦ no current flows; the cell is not at equilibrium
◦ None of these are correct.

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.

Nearly all drugs pass into human breast milk. How often a drug is taken influences the amount of drug that will pass into the milk. Medications taken 30 to 60 minutes before breastfeeding are likely to be at peak blood levels when the baby is nursing.

Did you know?

Studies show that systolic blood pressure can be significantly lowered by taking statins. In fact, the higher the patient's baseline blood pressure, the greater the effect of statins on his or her blood pressure.

Did you know?

Barbituric acid, the base material of barbiturates, was first synthesized in 1863 by Adolph von Bayer. His company later went on to synthesize aspirin for the first time, and Bayer aspirin is still a popular brand today.

Today, nearly 8 out of 10 pregnant women living with HIV (about 1.1 million), receive antiretrovirals.
