Question 1

A disproportionation reaction is one in which:
◦ the equation is not balanced
◦ the same substance is oxidized and reduced
◦ more of one substance reacts than another
◦ water must be added
◦ both reactants are reduced

Question 2

A piece of iron wire weighing 1.63 g is converted to Fe2+(aq) and requires 21.9 mL of KMnO4 solution for its titration. What is the molarity of the KMnO4 solution? The reaction occurring during the titration is:

5 Fe2+ (aq) + MnO4- (aq) + 8 H+ (aq) → 5 Fe3+ (aq) + Mn2+ (aq) + 4 H2O

◦ 1.33 M
◦ 0.267 M
◦ 2.67 × 10-4 M
◦ 14.9 M
◦ 1.33 × 10-3 M

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.
