(a) Interpretation: Whether in adiabatic expansion of an ideal gas, the gas is doing any work or not needs to be explained. Concept introduction: In adiabatic process, there is no heat change with the surrounding. The internal energy is defined as sum of heat evolved in the reaction and amount of work done. This is mathematically represented as follows: Δ E = q + w Here, q is heat and w is work done.

Solution Summary: The author explains that in an adiabatic expansion of an ideal gas, the heat of the system is constant and the internal energy is decreased.
Science that deals with the amount of energy transferred from one equilibrium state to another equilibrium state.

Interpretation Introduction
(a)
Interpretation:
Whether in adiabatic expansion of an ideal gas, the gas is doing any work or not needs to be explained.
Concept introduction:
In adiabatic process, there is no heat change with the surrounding. The internal energy is defined as sum of heat evolved in the reaction and amount of work done.
This is mathematically represented as follows:
ΔE=q+w
Here, q is heat and w is work done.
Interpretation Introduction
(b)
Interpretation:
Whether in an adiabaticexpansion internal energy is increased, decreased or remains same needs to be explained.
Concept introduction:
In adiabatic process, the heat of the system is not changed. So, the only source of work is internal energy.
The internal energy is defined as sum of heat evolved in the reaction and amount of work done.
This is mathematically represented as follows:
ΔE=q+w
Here, q is heat and w is work done.
Interpretation Introduction
(c)
Interpretation:
The change in the temperature of the gas during an adiabatic expansion needs to be explained.
Concept introduction:
In adiabatic process, the heat of the system is constant. The internal energy is defined as sum of heat evolved in the reaction and amount of work done.
1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in
your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on
the LC-MS printout. How much different are they?
2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit,
explain what each of these is and why they are present.
3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by
calculating the accurate monoisotopic mass.
4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum
of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source.
5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number). For one
point of extra credit, see if you can identify this molecule as well and confirm by…
Please draw, not just describe!
can you draw each step on a piece of a paper please this is very confusing to me
