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

What is the value ofQ, the reaction quotient, for this cell reaction?

Reference: 18-3


6.7 × 1040
1.5 × 10–41
1.5 × 10–4
6.7 × 103
None of these are correct.

Amoebae are the simplest type of protozoans, and are characterized by a feeding and dividing trophozoite stage that moves by temporary extensions called pseudopodia or false feet.

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Most women experience menopause in their 50s. However, in 1994, an Italian woman gave birth to a baby boy when she was 61 years old.
