When 235U fissions, the fission products are not always the same and exactly two neutrons are not always released. An example of one fission reaction is
You may want to use the following table of atomic masses:

1. What is the energy released in this fission?
Q =
2. Another example of possible results is
Q =
3. Lets assume that these are the only two fission reactions that take place (they are not), and that they take place at equal rates so the amount of energy released in every fission of 235U is the average of these two. How many gallons of gas would have to be burned to release the same amount of energy released when one kilogram of 235U undergoes fission? (A gallon of gasoline releases about 2.0X108J of energy when burned.)

In this problem, we're going get a rough estimate the amount of uranium fuel it would take if the US recieved all its electrical power from nuclear power plants. The size of a power plant in normally given as the about of electrical power it can produce when running a full capacity. This electrical power produced can be very different than the mechanical or thermal power that was required to produce this electricity. For example, power plant might have a...
3. A fission chain reaction. a. A neutron can cause 235U to fission, producing two daughter nuclei (tin and molybdenum) and three more neutrons. These three neutrons can then, in turn, cause three more 235U nuclei to split. One typical reaction is summarized as follows: n+25131Sn + 102Mo +3 n Find the energy released in this process (in MeV), given that MC3SU) 235.0439 u; M(3Sn) 130.9169 u; M(102Mo)-101.9103 u. b. Lise Meitner's work in 1938 predicted that the fission of...
Review Constants | Periodic Tat When a 99 U nucleus is bombarded by neutrons (n) it undergoes a fission feaction, resulting in the formation of two new nuclei and neutrons. The following equation is an example of one such fission process: U + n-Ba + Kr + 3on Enter the isotope symbol for the barium (Ba) nucleus in this reaction. Express your answer as an isotope.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
