Question 1

The reduction potentials for Ni2+ and Sn2+ are as follows:
Ni2+ + 2e– Ni, E° = –0.231 V
Sn2+ + 2e– Sn, E° = –0.140 V

Calculate the equilibrium constant at 25 °C for the reaction:
Sn2+ + Ni Sn + Ni2+

◦ 3.6 × 1012

◦ 35
◦ 5.9
◦ 8.3 × 10–4

◦ 1.2 × 103


Question 2

The standard free energies of formation of several species are:
 
kJ/mol
H+(aq)
0
H2O(l)
–237.0
CH3OH(aq)
–163.0
HCOOH(aq)
–351.2
e–
0
What is the standard reduction potential of methanoic acid in aqueous solution (i.e., for HCOOH + 4H+ + 4e– CH3OH + H2O)?


◦ 0.126 V
◦ 0.506 V
◦ –0.718 V
◦ –0.126 V
◦ 1.946 V

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

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.

Essential fatty acids have been shown to be effective against ulcers, asthma, dental cavities, and skin disorders such as acne.
