Question 1

The standard emf for the cell using the overall cell reaction below is +0.48 V:

Zn(s) + Ni2+(aq) → Zn2+(aq) + Ni(s)

The emf generated by the cell when [Ni2+] = 6.50 mol L-1 and [Zn2+] = 0.500 mol L-1 is
◦ 0.55
◦ 0.50
◦ 0.51
◦ 0.45
◦ 0.61

Question 2

The gas OF2 can be produced from the electrolysis of an aqueous solution of KF, as shown in the equation below:

OF2(g) + 2H+(aq) + 4 e- → H2O(l) + 2F-(aq)E° = +2.15 V
Using the given standard reduction potential, calculate the amount of OF2 that is produced, and the electrode at which the OF2 is produced, upon the passage of 0.480 faradays through an aqueous KF solution.
◦ 26.0 g of OF2 at the anode
◦ 6.48 g of OF2 at the cathode
◦ 6.48 g of OF2 at the anode
◦ 26.0 g of OF2 at the cathode

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
