The emperical formula for benzene (C6H6) is “CH”.
Are able to travel inside to conduct electricity
<h2>
Answer:
atoms</h2>
Explanation:
The given formula of the compound is 
The formula says
Every mole of
contains
moles of atoms of hydrogen.
Given that number of moles of compound is 
So,the number of moles of hydrogen atoms present is 
Since each mole has
atoms,
moles has
atoms.

Solution :
a). Applying the energy balance,



![$0=[mc(T_f-T_i)_{iron}] + [mc(T_f-T_i)_{water}]$](https://tex.z-dn.net/?f=%240%3D%5Bmc%28T_f-T_i%29_%7Biron%7D%5D%20%2B%20%5Bmc%28T_f-T_i%29_%7Bwater%7D%5D%24)


b). The entropy change of iron.


= -9.09 kJ-K
Entropy change of water :


= 10.76 kJ-K
So, the total entropy change during the process is :

= -9.09 + 10.76
= 1.67 kJ-K
c). Exergy of the combined system at initial state,






Therefore, energy of the combined system at the initial state is

= 63.94 -13.22
= 50.72 kJ
Similarly, Exergy of the combined system at initial state,





Thus, energy or the combined system at the final state is :

= 216.39 - 9677.95
= -9461.56 kJ
d). The wasted work



= 50.72 + 9461.56
= 9512.22 kJ
