The molecular formula tell us what elements the atoms are, and how many moles and atoms are attributed toward each element.
The molecular model tells us how the atoms/elements are bonded together.

Answer : The value of
for this reaction is 36.18 kJ
Explanation :
First law of thermodynamic : It states that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
As per first law of thermodynamic,
![\Delta E=q+w](https://tex.z-dn.net/?f=%5CDelta%20E%3Dq%2Bw)
where,
= internal energy of the system
q = heat added or rejected by the system
w = work done
As we are given that:
q = 38.65 kJ
w = -2.47 kJ (system work done on surrounding)
Now put all the given values in the above expression, we get:
![\Delta E=38.65kJ+(-2.47kJ)](https://tex.z-dn.net/?f=%5CDelta%20E%3D38.65kJ%2B%28-2.47kJ%29)
![\Delta E=36.18kJ](https://tex.z-dn.net/?f=%5CDelta%20E%3D36.18kJ)
Therefore, the value of
for this reaction is 36.18 kJ

The best example of immiscible liquids is
a polar liquid and a nonpolar liquid that do not dissolve into one another.
Explanation:
Immiscible averages that the fluids don't dissolve in each other – oil and water are an example. It is probable to swing up the juices and get them to mix but they soon separate. Departing immiscible liquids is done solely using a separating funnel.
