The daughter nucleus that is produced is ₂₉⁶³cu.
What is Electron capture?
The process of drawing an electron to the nucleus, where it combines with a proton to create a neutron and a neutrino particle, is known as electron capture.
The daughter nucleus is the nucleus that is made by the parent nucleus. The nucleus that remains after the decay is called the daughter nucleus.
Here is the chemical formula for the reaction that results in the electron capture of the zinc-63 nucleus:


Thus, the daughter nucleus produced when zn63 undergoes electron capture is
.

The answer to this would be d. Precipitation patterns .
The answer is B
Vaporization
Explanation:
As it is known that
molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.

= 
= 18 R
Also, 
where,
= molar heat capacity
M = molecular mass
= specific heat
Hence, calculate the value of
as follows.



This means that value of isochoric specific heat is
.
Yes, we have to assume ideal gas behavior because for ideal gas:
dU = 
Whereas for real gases "
" has to be added here.
