What is the emf of a galvanic cell consisting of a Cd2+/Cd half-cell and a Pt/H+/H2 half-cell if [Cd2+] = 0.28 M, [H+] = 0.21 M, and PH2 = 0.62 atm?
What is V?
Do I use the equation:
E = E - (.0257V / n) lnQ
What do I put in for E initial?
In Madeleine L'Engle's children's novel A Wrinkle in Time, the mitochondria in one of the characters starts to die. Describe what would happen to people who lost their mitochondria, and explain why it would happen.
Pb(s)| Pb2+ (1M) || Ag+ (1M) | Ag(s)
Determine which of the following statements about the cell shown are True or False.
The silver half-cell is the anode.
The mass of the silver electrode is increasing.
Electrons are spontaneously produced in the lead half-cell.
As the reaction proceeds, the concentration of the silver
1. A cell is located over smooth, flat terrain. The system operates in the 1900 MHz band and the base station antenna is located 15 m above the ground. The mobile terminal is 250 m away from the base and its antenna is 1.5 m above the ground. (Use 1920 MHz in your computations.)
(a) Compute the propagation loss.
(b) What is
In couples where each person is heterozygous for the sickle-cell gene, there is a probability of 0.25 that any child of the couple will have the disease. A husband and wife, who are both heterozygous for the sickle-cell allele, are planning to have a family of four children.
What is the probability that their first child wil
In a cell, there is less water on the inside and less glucose on the outside. Water wants to enter the cell and the cell wants to transport in more glucose. Relative to the cell, what type of environment is this? How will the cell be able to have both the water and glucose enter?
