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)
The correct answer is a descriptive investigation.
An investigation which does not involve hypotheses called descriptive investigation.
Hypotheses are termed as scientific hypotheses and require that one can test it. In hypothesis, previous observation can not satisfactorily be explained with an available scientific theory.
Working hypotheses are being proposed for further research.
Hello there.
<span>Why are carbon and nitrogen essential for survival to all living organisms?
</span>
<span>They are needed to release the energy stored in food.
</span>Therefore, The correct answer would be Option B.
Answer: Mass of
produced in this reaction was 6.56 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Mass or reactants = Mass of
+ mass of
= 16.00 + 64.80 = 80.80 g
Mass of products = mass of aqueous solution + mass of
+ = 74.24 + x g
Mass or reactants = Mass of products
80.80 g = 74.24 + x g
x = 6.56 g
Thus mass of
produced in this reaction was 6.56 grams
