All Questions must be 2-5 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. Make sure to Answer MUST INCLUDE correct sig figs
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) Answer MUST INCLUDE correct sig figs
Question 4A: Explain what type of nuclear reaction has occurred and what particle is emitted. Answer MUST INCLUDE correct sig figs
Question 4B: Has transmutation occurred?

Answer 1

Question 1: Fusion reactions involve the combining of two light nuclei to form a heavier nucleus, releasing energy in the process. Fission reactions involve the splitting of a heavy nucleus into two lighter nuclei, also releasing energy.

Question 2: Two isotopes involved in fusion reactions are Deuterium (2H) and Tritium (3H).

Question 3: X = 234, y = 91, Z = 143. To demonstrate conservation of mass, we need to calculate the number of protons, neutrons, and electrons on both sides of the reaction. This will show that the number of each subatomic particle remains the same.

Question 4A: Y is the atomic number of the product, Z is the mass number of the product. A beta decay nuclear reaction has occurred, and a beta particle is emitted.

Question 4B: Yes, transmutation has occurred in this reaction.
