9) When aluminum-27 is bombarded with a neutron, a gamma ray is emitted. What radioactive isotope is produced? silicon-27 silicon-28 aluminum-28 magnesium-27 magnesium-28 10) Iodine-123, which is used for diagnostic imaging in the thyroid, has a half-life of 13 h. If 50.0 mg of I-123 were prepared at 8:00 A.M. on Monday, how many mg remain at 10:00 A.M. on the following day? 50.0 mg 25.0 mg 12.5 mg 6.25 mg 3.13 mg 11) Krypton-79 has a half-life of 35...
6 of 12 Exam 3 (cont) A neutron strikes a deuteron, and they combine to form a tritium nucleus. (A neutron, a deuteron, and a tritium nucleus are all sub-atomic particles.) The neutron's initial momentum was p=(2.0 x 10-20) kg mg 14. i and the tritium nucleus leaves the reaction with momentum p initial momentum? m j What was the deuteron's -(1.0 x 10-0) kg-m + (4.0 x 10-0) Pas+(10x 10-0)k m+ (4.0 x 10 j Pa-+(1.0 x 10-0) &g...
When atoms of beryllium-9 are bombarded with alpha particles, the C-12 isotope is formed along with what other particle? 4 9 He+ 12c + Be - 2 4 6 neutron proton gamma particle alpha particle beta particle
Question 1 (8 marks in total) The deuteron is a bound state of a proton and a neutron. Treating nucleons as identical particles with spin and isospin degrees of freedom, the total state of the deuteron can be writ- ten space Ψ spin Ψ isospin. The deuteron has a total angular momentum quantum number J - 1 and a total spin S -1. Our goal is to determine the parity of the deuteron Q1-1 (1 mark) Show that the possible...
Enter your answer in the provided box. The 235U isotope (atomic mass = 235.00) undergoes fission when bombarded with neutrons. However, its natural abundance is only 0.72 percent. To separate it from the more abundant 238U isotope (atomic mass = 238.00), uranium is first converted to UF, which is easily vaporized above room temperature. The mixture of 23SUF, and 238UF gases is then subjected to many stages of effusion. Calculate how much more quickly 235UF, effuses than 238UF. Give the...
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.

1) Answer the questions about the 2-hexanone. a) When bombarded with electrons in EIMS, what is the most likely (most stable) radical cation that is formed? b) From this radical cation, two alpha cleavage reactions are likely. Draw the mechanism of both and predict the fragments c) In addition to alpha cleavage, this molecule can also undergo a McLafferty rearrangement mechanism to predict the fragments . Drawa
4) |Ql A proton and a deuteron are initially at rest, a distance of 2 nm apart. They have the same c twice as massive as the proton. How fast will they be moving when they are very far apart?
