You are at a political party with some friends. A candidate for state office states that working women earn about 70 cents for each dollar that working men earn. The candidate says, "This is clearly evidence that employers discriminate against women. The gap between the earnings of men and women will never close because professions women tend to choose are traditionally low paying and the professions men choose are traditionally high paying. I propose that the government create a panel to decide what jobs should pay so that people of similar skills and education earn the same amount." Do you agree or disagree with the candidate's idea? What are the consequences of creating such a panel? Should we let the market mechanism to solve any wage discrimination? Discuss and justify your opinions on the subject matter.

A report by the NCAA states that 57.6% of football injuries occur during practices. In a recent study of 52 injuries, 32 of the injuries occurred during practice. At the 0.06 level of significance, can it be concluded that the percentage of football injuries that occur during practices is greater than 57.6%? Show your work to receive credit.

The rule of Dulong and Petit states that the molar heat capacities of the metallic elements are approximately constant. Estimate the value of this constant by calculating the molar heat capacities of the following metals from their specific heats and taking the average.

Average: _________ J mol^-1 K^-1

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,733. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,850 and a standard deviation of $3500. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,733? Test the relevant hypotheses using

α = 0.05.

(Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

. Regarding the folded and unfolded states of a protein (2 pt): a. Do they have the same peptide bonds? b. Do they have the same non-covalent interactions? c. Which state has more water-exposed non-polar side chains? d. Which state has higher enthalpy? Why? e. Which state has higher entropy if we consider the surrounding water molecules? Why?

Dalton's law states that the total pressure, Ptotal, of a mixture of gases in a container equals the sum of the pressures of each individual gas:

Ptotal=P1+P2+P3+…

The partial pressure of the first component, P1, is equal to the mole fraction of this component, X1, times the total pressure of the mixture:

P1=X1×Ptotal

The mole fraction, X, represents the concentration of the component in the gas mixture, so

X1=moles of component 1total moles in mixture

Question 1 ---- Three gases (8.00 g of methane, CH4, 18.0 g of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 ∘C, the total pressure in the container is 3.50 atm . Calculate the partial pressure of each gas in the container.

Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.

Part 2 ----

A gaseous mixture of O2 and N2 contains 34.8 % nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 665 mmHg ?

Express you answer numerically in millimeters of mercury.
