Explanation:
The given data is as follows.
Moles of propylene = 100 moles, = 100 J/mol K
= 300 K, = 800 K
= 2 , = 0.02
Therefore, the assumptions will be as follows.
- The given system is very well insulated.
- The work is done on the system because the given process is a compression process.
- Assume that there is no friction so, work done on the system is equal to the heat energy liberated.
= W
Putting the given values into the above formula as follows.
= W
W =
= J
= 5 MJ
Hence, this shows that a minimum of 5 MJ work needs to be done.
Since, work is very less. Hence, it will not compress the given system to 800 K and 0.02 .
In my opinion, the correct answer among the choices above is option B. AN atom having four electrons in its valence shell is capable of single, double, or triple covalent bonds. This is because 4 electrons of the atom can be shared with other atoms.
The answer is (B).
Hope this helps :).
Explanation:
As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.
As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.
So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.
Therefore, concentration of chlorine ions will be calculated as follows.
Concentration of ions =
= 0.6 mM
Thus, we can conclude that the concentration of chloride ions is 0.6 mM.
