Test Tube 1: Analysis a) Write the equation from your lab notebook for this dissolution CaCl2(S) + 2H2O(s) → Ca(OH)2(aq) + HCl(g) b) Use the recorded values in your lab notebook to calculate both the molarity and the molality of the solution. (the density of water at room temperature is 0.997 g/mL) c) Insert the graph of your temperature change and report the ΔT. d) Sketch or insert an image of the matching energy diagram (see the figure in the lab for an example). Label as endothermic or exothermic. Endothermic e) Use the heat capacity of water (4.184 J/g°C) to calculate the energy change of the water in Joules f) Consider the entire solvation process as a series of steps in the energy diagram and answer these questions. Name the strongest attractive forces that exist in the 1) solid and 2) liquid that must be broken? Will breaking these forces be an endothermic or exothermic process? Name the attractive force (IPF) that is being created? Will this step be endothermic or exothermic? Was the enthalpy of solution (the overall energy change) endothermic or exothermic? Label the energy diagram with this answer Test Tube 2 Analysis - Part A: a) Write the equation from your lab notebook for this dissolution. b) Use your recorded data to calculate the molarity and the molality of the solution. c) Insert the graph of your temperature change and report the ΔT d) Sketch or insert the matching energy diagram (see the figure in the lab for an example). Label the energy diagram as endothermic or exothermic. e) Use the heat capacity of water (4.184 J/g°C) to calculate the energy change of the water in Joules Test Tube 2 Analysis- Part B: Rewrite the equation for the supersaturated solution as it cooled down from your lab notebook K+NO3(s) → K(aq) + NO3(aq) + Energy State where the energy in this equation is coming from and where it is going as potassium nitrate crystallizes. Be sure to identify if the forms of the energy as kinetic or potential energy.

With respect to the graph and overall question, I am looking for the answer to question #2: With no penalty on buyers, if a penalty for breaking the laws is imposed on sellers at more than $5 per disc, what is the equilibrium price of an illegal disc? Hollywood: Organized Crime Hits the Movies Price (dollars per DVD): 12 The Mexican army seized 1,180 disc burners and 3.14 million copies of movies and TV shows from 23 warehouses in a move to fight piracy that costs Hollywood about $590 million a year. Source: Bloomberg Businessweek, April 7, 2011 Price (dollars per DVD): 10 C Assume that the marginal cost of producing a DVD (legal or illegal) is a constant $3 and that legal DVDs bear an additional marginal cost of $5 each in royalty payments to film studios. 1. Suppose the equilibrium quantity of illegal DVDs is 3 million per year. Draw the supply curve of illegal DVDs and label it S. Draw the demand curve for illegal DVDs and label it D. Draw a point at the equilibrium price and equilibrium quantity and label it 1. Draw a curve to show the effect of the events reported in the news clip and label it. (Note: CBL is short for Cost of Breaking the Law.) Draw a point at the new equilibrium price and equilibrium quantity and label it 2. S * CBL 2. With no penalty on buyers, if a penalty for breaking the law is imposed on sellers at more than $5 per disc, what is the equilibrium price of an illegal disc?
