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. Only correct answers and in Sig Figs.
Question 4B: Has transmutation occurred, what type be specific?

1 answer

Question 3: X = U, Y = 235, Z = 92. Using 92 protons and 143 neutrons on the reactant side and 91 protons and 144 neutrons on the product side, conservation of mass is maintained. The numbers of protons and neutrons balance on both sides of the equation.
Question 4A: An alpha decay reaction has occurred and alpha particles are emitted.
Question 4B: Yes, transmutation has occurred in this reaction with alpha decay specifically.
