The answer is physical adaption.
Answer:
a) E = 17.55 MeV
b) E = 18.99 MeV
c) E = 3.29 MeV
d) You can use the methods applied for the other parts to solve this, the equation is not properly written
e) E = 4.075 MeV
Explanation:
Energy Released, 

Mass of 1H, 
Mass of 2H, 
Mass of 3H, 
Mass of Helium, 
Mass of Beryllium, 
Mass of neutron, 
a) 

Energy released,

Energy released = 17.55 MeV
b) 

Energy released,

c)
+ n

Energy released,

E = 3.29 MeV(Energy is released)
d) You can use the methods applied for the other parts to solve this, the equation is not properly written
e) 


E = 4.075 MeV ( Energy is released)
Answer:
the answer would be the first one, gamma decay
<span>The correct answer is 1. compound. There are three elements and not just one so it's not element. Mixtures wouldn't have the same properties that you described but these do so it's a compounds. Solution is not a solid thing but rather a liquid one. The two samples are therefore compounds.</span>
