4. Market research has revealed the following information about the market for chocolate bars: The demand schedule can be represented by the equation QD = 1600 − 300P, where QD is the quantity demanded and P is the price. The supply schedule can be represented by the equation QS = 1400 + 700P, where QS is the quantity supplied.

6.Consider the following information from the market for lemonade:
|Price||Quantity Demanded||Quantity Supplied|
|$1||500 cups||150 cups|
|$2||200 cups||310 cups|
(a) As the price changes from $1 to $2, what is the value of price elasticity of demand?
(b) As the price changes from $1 to $2, what is the value of price elasticity of supply?
(c) Sketch a diagram demonstrating the market for lemonade. Are the supply and demand curves relatively inelastic or elastic? Explain.
(d) Suppose that when the price of lemonade increases from $1 to $2, the quantity demanded of orange juice increases from 150 cups to 190 cups. Calculate cross-price elasticity of demand for orange juice.
(e) Are orange juice and lemonade substitute or complementary goods? Explain.
7. Suppose that business travelers and vacationers have the following demand for airline tickets from New York to Boston:
(a) As the price of tickets rises from $200 to $250, what is the price elasticity of demand for (i) business travelers and (ii) vacationers? (Use the midpoint method in your calculations)
(b) Why might vacationers have a different elasticity from business travelers?
8. Suppose the price elasticity of demand for heating oil is 0.2 in the short run and 0.7 in the long run.
(a) If the price of heating oil rises from $1.80 to $2.20 per gallon, what happens to the quantity of heating oil demand in the short run? In the long run? (Use the midpoint method in your calculations)
(b) Why might this elasticity depend on the time horizon?
9. The Government has decided that the free-market price of cheese is too low.
(a) Suppose the government imposes a binding price floor in the cheese market. Draw a supply-and-demand diagram to show the effect of this policy on the price of cheese and the quantity of cheese sold. Is there a shortage or surplus of cheese?
(b) Farmers complain that the price foor has reduced their total revenue. Is this possible? Explain
(c) In response to farmer's complaints, the government agrees to purchase all the surplus cheese at the price floor. Compared to the basic price floor, who benefits from this new policy? Who loses?
You are a counselor working with a married couple, Bryan and Dustin, in which Bryan is an active duty marine for the US military. Bryan is on leave from duty, and the pair is seeking counseling for concerns that have arisen in their seven-year relationship. Each time they wish to start counseling to address their concerns, Bryan gets called to duty, which stalls any progress they could make. After his most recent tour and prior to his leave, Bryan was injured and has been experiencing physical pain. In the most recent session, Dustin has disclosed he is concerned with Bryan's recent increased alcohol use and its impact on their social life and relationship. Dustin was noticeably uncomfortable in discussing these concerns while Bryan seemed disinterested in the conversation. In this session Dustin also disclosed that over the last week when Bryan was drinking he pushed and hit Dustin when he was trying to help Bryan to bed. Bryan attempted to downplay the incident saying "it was nothing." During this altercation, Bryan told Dustin that he "just wants to get back to his unit" and "can't wait to get the doctor's okay" to return to service, "which was hurtful" to Dustin. You've assessed that Bryan is not at risk for suicide, and although you are not a part of the VA system, you are aware of certain criteria for active duty service (e.g., fitness to perform, chain of command, potential military conduct violations).
Using the ethical decision model answer each question as it relates to this scenario
- Identify the problem
- Determine the nature and dimensions of the dilemma
- Generate potential courses of action
- Consider the potential consequences of all options and determine a course of action
- Evaluate the selected course of action

- .Be specific how each ethical value are related to the dilemma. For example what about this ethical dilemma will impact autonomy and how does autonomy impact this decision making. (please do not restate the definitions for the ethical values)
Ethical values include : autonomy, non-maleficence, beneficence, and justice.
7.In addition, List one main point or idea that a mental health therapist should take to assist the client with the ethical dilemma noted above in addition to seeking supervision.
Liquid benzene is pumped from storage and vapourised using a heat exchanger (W301) which utilizes low pressure steam as a source of energy, producing a fresh feed of dry organic vapour which is subsequently mixed with excess air which is drawn from outside, compressed and subsequently heated to the same temperature as the benzene gas stream. The gas stream temperature is increased by passing the vapour through a heat exchange system within a methane-fired furnace (D301) with combustion products venting to atmosphere through the chimney. The hot gases move to an isothermal reactor (C301) where 100% of the Benzene is converted per pass. The reactor temperature is held constant using cooling water. The gaseous reactor products are immediately cooled to 110°C by exchanger (W303) and proceed to an absorption column(also at 110°C) where gas and the absorbing liquid are contacted in a counter-flow arrangement. Maleic anhydride is extracted into a descending stream of liquid dibutyl phthalate. All other gases entering, including those formed by complete combustion of benzene within the reactor can be considered to be insoluble and are purged from the absorber. The product-containing solution passes to a column (K302) operating with a steam - fed external reboiler and total condenser. The single - component bottom product is recycled back to the absorber. The top product, which is pure and contains no contaminants, is sent to storage. Use Microsoft Visio and draw this
A 0.16 mol dm−3 solution (3.50 cm3) of s-butyllithium in toluene was
added to a solution of styrene (8.40 g) in toluene (200 cm3). After
complete conversion of the styrene, isoprene (28.00 g) was added.
When the isoprene had completely polymerized, the reaction was
completed by addition
of a 0.10 mol cm-3 solution (2.80 cm3) of dichloromethane in toluene.
(a) Write down the reactions occurring in each stage of this reaction
sequence and show the structure of the final polymer. (b) Evaluate the
relevant degrees of polymerization and the corresponding molar masses
for the final polymer.
