3. The following is an excerpt from a letter sent by Henry Wallace to President Truman, July 23, 1946. From the ...

. From the Harry S Truman Papers, Harry S Truman Library, Independence, Missouri. Henry Wallace, a former Vice President of the United States, was a critical observer of US policies during the start of the Cold War. He believed US actions were as much to blame as Soviet actions in the starting of the Cold War. “How do American actions since V-J Day appear to other nations? I mean by actions the concrete things like $13 billion for the War and Navy Departments, the Bikini tests of the atomic bomb and continued production of bombs, the plan to arm Latin America with our weapons, production of B-29s and planned production of B-36s, and the effort to secure air bases spread over half the globe from which the other half of the globe can be bombed. I cannot but feel that these actions must make it look to the rest of the world as if we were only paying lip service to peace at the conference table. These facts rather make it appear either (1) that we are preparing ourselves to win the war which we regard as inevitable or (2) that we are trying to build up a predominance of force to intimidate the rest of mankind. How would it look to us if Russia had the atomic bomb and we did not, if Russia had 10,000-mile bombers and air bases within a thousand miles of our coastlines, and we did not? Our basic distrust of the Russians, … stems from differences in political and economic organization…I am convinced that we can meet that challenge as we have in the past by demonstrating that economic abundance can be achieved without sacrificing personal, political and religious liberties. Our actions to expand our military security system-such steps as extending the Monroe Doctrine to include the arming of the Western Hemisphere nations, our present monopoly of the atomic bomb, our interest in outlying bases and our general support of the British Empire-appear to them as going far beyond the requirements of defense.” Henry A.

5.6. In many important reactions, oxygen from the atmosphere is a participant. When iron “rusts” through a series of redox ...

hrough a series of redox reactions involving water and oxygen, the ultimate reaction is Fe (iron) + O2 (molecular, elemental oxygen) Yields Fe2O3 (red rust). The charge of iron in rust is +3; the charge of oxygen in rust is -2. a. What is the charge of metallic iron? Atmospheric oxygen? How do you know? b. What is oxidized in this reaction? What is reduced? 7. In raku firing of ceramics, a piece of clay is formed, then glazed, often with some type of copper, iron, cobalt, or other metallic compound. The product is removed hot from the kiln and placed in a container of sawdust, leaves, or other combustible materials. The burning quickly consumes all the oxygen, and produces a “reductive” environment. You know that the half reaction: Cu yield Cu+2 + 2 e- is an oxidation. a. Write this in reverse to show what happens to the copper ions in glazes in a reductive environment. Explain, then, why raku firing yields interesting effects.

8.In a city with a population of 100,000 people, the spread of an influenza epidemic follows the differential equation: dy / ...

rential equation: dy / dt = py (100000 - y) Where: y is the number of infected people at time t (measured in weeks) and p = 0.00001. If 10 people were ill, determine y as a function of t. How long will it take before half the population is infected?
