Consider a market consisting of several small pulp & paper mills operating in the South-east. These firms discharge chlorine and other waste products into nearby rivers and streams. The rivers and streams are not privately owned, and the mills’ discharges are currently unregulated by the EPA or by the states’ environmental agencies. The demand for paper produced by the mills in this market is P = 800 - 0.5Q. The marginal cost of producing paper in this market is MC = 20 + 0.3Q, where P and MC are expressed in dollars, and Q is expressed in tons of pulp and paper.

a. Determine this market’s equilibrium price and quantity, total revenue, marginal cost, consumer and producer surplus.

b. University researchers estimate that chlorine emissions from the industry's production impose costs, unaccounted for the industry or the market in which it operates, equal to P = 0.05Q. Determine the market’s efficient equilibrium price and quantity when all costs are accounted for.

c. The researchers then suggest that a tax, equal to the unaccounted for costs, be imposed on the production of pulp & paper in this market. What is the dollar amount of the tax? How much in revenue would the government collect? Would the market be inefficient with the tax? Explain (briefly and concisely) your answer.

Given the following list of values, perform a binary search for the indicated search item. Use the binary search algorithm on pg. 1026 of our textbook. Show the values of first, last and middle, and the number of comparisons made after each iteration of the loop. Your should create a table like the following to show your work, where first and last are the values of the variables at the beginning of the loop, and mid is the midpoint used during that iteration, list[mid] is the value in the list at the midpoint, and No. of key comparisons should be the number of comparisons made during this iteration by the algorithm:

Iteration  first   last    mid  list[mid]   No. of key comparisons
1          0       12      ?    ?           ?

List:
[ 2, 3, 4, 4, 5, 7, 10, 14, 15, 17, 22, 23, 24 ]

Marin Construction Company began work on a $424,000 construction contract in 2020. During 2020, Marin incurred costs of $279,500, billed its customer for $204,500, and collected $170,500. At December 31, 2020, the estimated additional costs to complete the project total $150,500. Prepare Marin’s journal entry to record profit or loss, if any, using (a) the percentage-of-completion method and (b) the completed-contract method.

A chemist weighed out 1.654 g of a mixture containing unknown amounts of iron (Fe) and lead (Pb) and placed the sample in a 0.500 L flask containing O2 (g) at 24.0 C and 846 torr. After heating, the reaction to form Fe2O3(s) and PbO2(s) was completed, the vessel was cooled to 24.0 C and the pressure of O2 (g) remaining was 452 torr. Calculate the mass percentage of lead in the mixture. Molar masses (g/mol) : PbO2: 239.20; Fe2O3: 159.69; Pb: 207.20; Fe: 55.85

When exposed to air, aluminum metal, Al, reacts with oxygen, O2, to produce a protective coating of aluminum oxide, Al2O3, which prevents the aluminum from rusting underneath. The balanced reaction is shown here: 4Al+3O2→2Al2O3

What is the theoretical yield of aluminum oxide if 2.20 mol of aluminum metal is exposed to 1.95 mol of oxygen?
