Which of the following statements is true? a. fission does not release energy. b. fusion releases more energy than fission. c. fission releases more energy than fusion. d. higher temperatures are required to initiate a fission reaction than are required to initiate a fusion reaction.

A.Fission does not release energy. - Wrong Fission releases energt

B.Fusion releases more energy than fission. - Wrong the opposite is true

C.Fission releases more energy than fusion. - True (Answer)

D.Higher temperatures are required to initiate a fission reaction than are required to initiate a fusion reaction.  - The opposite is true on this one as well

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
