Question
6C14(14.003242 u) decays to 7N14 (14.002525 u) by ? emission. (-1e0=0.000549 u)
a. Write a nuclear equation for this decay process. Use a minus sign and greater than sign -> for the right arrow symbol for the decay in the equation. Use no parentheses or spaces. Write the elements as 6C14, 7N14, -1e0.
Answer
b. Which material is called the Parent Nucleus?
Answer
c. Which material is called the Daughter Nucleus?
Answer
d. Calculate the total nuclear mass before the decay.
mtotal=Answer u
e. Calculate the total nuclear mass after the decay.
mtotal=Answer u
f. Calculate the change in nuclear mass. Where does this energy go?
?m=Answer u
This energy goes to Answer of the particles.
g. Calculate how much energy is given off by this nuclear decay.
?E=Answer MeV
Explanation / Answer
A)6C14--->7N14+-1e0
B)6C14
C)7N14
D)14.003242u
E)14.003074u
F)?m=14.002525+0.000549-14.003242
=-0.000168u
G)?E=?mc^2
=0.000168 u*c^2
1 amu = 931.4941 MeV/c2
=0.000168*931.941
=0.156 Mev
