When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.
<h3>What is a covalent compound?</h3>
A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.
One of the major factors that affect compounds with covalent bonds is temperature.
The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.

#SPJ1
Atomic mass is number of protons + number of neutrons (disregard electrons in mass calculations). 104 + 157 = 261.
Here are the list of nucleo bases : adenine , Thymine, Guanine , Cytosine
Adenine pairs with Thymine, and Guanine pairs with Cytosine
Adenine + Guanine = Purine
Thymine + Cytosine = Pyrimidine
So the answer for number 1 will be : Purine, since Adenine is not the choice
And the answer for number 2 is Guanine
hope this helps
It’s C I think and I’m not sure
Answer:
The answer is "52.8".
Explanation:
Please find the graph file in the attachment.
They have the atoms in 8 corners with one unit cell in an one so mesh (SCC).
Atoms throughout the corner contribute 
to both the cell unit
Atom number per SCC unit cell, 
Let 'r' become the atom's radius. 
We can see from the diagram that edge length
