D. I or Iodine
This is because they are both in the same periodic family (the halogens) and thus the number of valence electrons are the same
Explanation:
b. Bromo cyclopentane + HBr
Answer:
25kJ
Explanation:
Given the initial energy to be 30kJ
The energy change from the initial energy to the peak energy = (65-30) kJ
= 35kJ
since the second energy change was a drop in energy it is regarded negative
= (55-65)
= -10kJ
Therefore total energy change
= (35-10)kJ
= 25kJ
