Question 1

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

Mg(s) + Cu2+(aq) → Cu(s) + Mg2+(aq)

Mg2+(aq) + 2 e⁻ → Mg(s) E° = -2.38 V
Cu2+(aq) + 2 e⁻ → Cu(s) E° = +0.34 V

◦ -2.04 V
◦ +1.36 V
◦ +2.04 V
◦ +2.72 V
◦ -1.36 V

Question 2

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

2K(s) + I2(s) → 2K⁺(aq) + 2I⁻(aq)

K+(aq) + e⁻ → K (s) E° = -2.93 V
I2(s) + 2 e⁻ → 2 I⁻(aq) E° = +0.54 V

◦ +1.85 V
◦ +5.32 V
◦ +3.47 V
◦ -5.32 V
◦ +6.40 V

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).

Did you know?

More than 30% of American adults, and about 12% of children utilize health care approaches that were developed outside of conventional medicine.

Did you know?

The strongest synthetic topical retinoid drug available, tazarotene, is used to treat sun-damaged skin, acne, and psoriasis.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Did you know?

Disorders that may affect pharmacodynamics include genetic mutations, malnutrition, thyrotoxicosis, myasthenia gravis, Parkinson's disease, and certain forms of insulin-resistant diabetes mellitus.
