Choose a concept from any 3 author we studied (Kant, Marx, Mill, Rand, Gandhi, or Nietzsche) and give me an application/example of it (can be from the news, a personal story, something you learned in another class, etc.). Make sure to EXPLAIN the concept AND how it applies.

(a) Starting from entropy as a function of pressure and volume, S(P, V), show that
d S = C V T ( ∂ T ∂ P ) V d P + C P T ( ∂ T ∂ V ) P d V
For a certain gas that follows the following equation of state:
P(V-b) = RT
Where b is a constant
(b) Starting from the above relationship show that P(V-b)γ=constant for the reversible adiabatic process. Assume constant heat capacity and γ=CP/CV as that for the ideal gas.

GRAPH THEORY
Prove/Show that a connected Graph G is not separable if and only if it is nonseparable.
Definitions for Reference: A connected Graph G is called nonseparable if it has no cut vertices (A vertex v in a connected graph G is caled a cut vertex if G-v is disconnected)
A connected graph G is called separable if there exist subgraphs H1, H2 ⊂ G. with E(H1) ∪ E(H2) = E(G) and E(H1) ∩ E(H2) = ∅. V (H1) ∪ V (H2) =V (G) and V (H1) ∩ V (H2) containing a single vertex.

Section I
You toss a coin and roll a die simultaneously. If the coin shows
heads, the experiment outcome is equal to the value shown on the
die. If the coin shows tails, the experiment outcome is equal to
twice the value shown on the die. Assume that the coin and the die
are fair. Let ? be 1 if the coin shows heads and 2 if the coin
shows tails, ?be the outcome of rolling the die, and ? the outcome
of the experiment. Notice that ?, ?, and ? are random
variables.
What is the minimal sample space in this experiment? (4 points)
Identify the event that the outcome of the experiment is, at least, 10. (4 points)
What is the value of ??(? ≤ 9)? (4 points)

1. Add 0.5 mL of 0.10 M NiCl2 solution to each of 7 test tubes using dropper provided. Label these tubes 1 through 7. 2. Add the following to the respective tubes containing the NiCl2 solution,
Tube 1: 5 drops of water (used here as a control experiment for dilution)
Tube 2: 1 mL of conc. HCl
Tube 3: 5 drops of conc. ammonia
Tube 4: 5 drops of dilute (5% v/v) ethylenediamine solution
Tube 5: 5 drops of 0.25 M C2O4 2- (oxalate) solution
Tube 6: 5 drops of 0.1 M SCN- (thiocyanate) solution
Tube 7: 5 drops of 0.1 M EDTA solution Mix each solution thoroughly and be sure to note the colour of each tube.
3. Check the stability of each complex by adding 3-5 drops of 1 M NaOH solution. Note any changes (e.g., formation of precipitate, colour change, etc.)
4. Add 0.5 mL of 0.10 M CuSO4 solution to each of 7 new test tubes labeled 8 through 14 using dropper provided. Repeat steps 2 and 3.
The “field strength” of a ligand describes how strong the coordination bond is, for a given metal and the ligand that is considered. The field strength is evaluated by considering how much it causes the d orbitals to split (DE), which of the ligands is strongest? Which is the weakest? Explain your choices in each case.
