All Questions must be 5-7 Sentences, and include correct capitalization or punctuation.

Question

• All set up and steps of work must be shown
• Answer MUST INCLUDE correct sig figs and correct units
• All MOLAR MASSES MUST be calculated with NO rounding from the periodic table.
_____

Question 1- Explain the different processes that occur during fusion and fission reactions.

Question 2- Name two isotopes involved in fusion reactions.

Question 3 & 4A and 4B are combined.
234. 234
235. X → 91 y+Z

Question 3: Identify X, Y and Z. Must use simple math to show work and explain how many protons, neutrons, and electrons each of the products and reactants have to demonstrate that both sides of the reaction meet the requirement of conservation of mass. (class notes have example problems)
Question 4A: Explain what type of nuclear reaction has occurred and what particle is emitted.
Question 4B: Has transmutation occurred?

Answer 1

Question 1: Fusion reactions combine two light nuclei to form a heavier nucleus, releasing a large amount of energy. Fission reactions involve the splitting of a heavy nucleus into two lighter nuclei, also releasing energy. In fusion, like in the sun, hydrogen atoms combine to form helium, while in fission, uranium atoms split into lighter elements.

Question 2: Two isotopes involved in fusion reactions are deuterium (2H) and tritium (3H), which combine to form helium (4He).

Question 3: X = 91, Y = 234, and Z = 1. The total number of protons, neutrons, and electrons on both sides of the reaction should be equal to show the law of conservation of mass.

Question 4A: A fission reaction has occurred in this nuclear equation, and a neutron is emitted as indicated by the arrow.

Question 4B: Yes, transmutation has occurred in this reaction as the starting element Uranium-235 was transformed into Y and Z.
