(1) Under acidic conditions, MnO2 becomes Mn2+. Write the balanced half-reaction for this transformation. (Omit states-of-matter from your answer.)
(2) Balance the following half-reaction under basic conditions. NO3− → NH3
(3) Balance the following redox (oxidation-reduction) reaction under basic conditions. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.

Flying over the western states with mountainous terrain in a small aircraft is 40% riskier than flying over similar distances in flatter portions of the nation, according to a General Accounting Office study completed in response to a congressional request. The accident rate for small aircraft in the 11 mountainous western states is 3.5 accidents per 100,000 flight operations. Find the probability of no accidents in 100,000 flight operations. (Use 4 decimal places.) Find the probability of at least 8 accidents in 180,000 flight operations. (Use 4 decimal places.)

While being interviewed about the status of education,
a politician states that at least
20% of all new teachers leave the profession within the first three
years. If 216
teachers hired three years ago are selected at random, find the
probability that 33 or
fewer teachers were no longer teaching.

Is there a difference in mean humidity levels among the three
states of Utah, Minnesota, and Georgia? Humidity was recorded in
the early morning (12:58am) of 14 June 2013 in five randomly
selected towns in each of the three states. . Data are presented
below. Use ANOVA for this analysis. Create an APA styled results
presentation. This will include a table of results, and written
inference and interpretation.
Georgia: 76%, 85%, 93%, 96%, 77%
Minnesota: 67%, 68%, 65%, 73%, 73%
Utah: 21%, 26%, 13%, 43%, 36%

Problem: Each student must create and solve an apportionment problem using what you have learned in this chapter. The problem must have at least four "states" and 30 "seats". You must choose one of the four methods presented in this chapter (Hamilton's, Jefferson's, Adams' or Webster's) to apportion the "seats". If you use Hamilton's Method, you must go on to demonstrate the occurrence of one of the paradoxes (Alabama, Population, or New States). If you use one of the divisor methods, it must violate the quota rule.
