Read the article "Are Emily and Greg More Employable than Lakisha and Jamal? A field Experiment on Labor Market Discrimination" by M. Bertrand and S. Mullainathan. Write a one page summary of the article stating its main question, empirical strategy used (explain why they chose to use it) and main conclusions. Also add a paragraph with your assessment of the article (for example, do you find weaknesses? what are the main strengths?

A compound containing only C, H and O was subjected to combustion analysis. A sample of 9.550×10^-2 g produced 1.825×10^-1 g of CO₂ and 1.120×10^-1 g of H₂O. Determine the empirical formula of the compound and enter the appropriate subscript after each element.

If the molar mass of the compound is 184.276 g/mol, determine the molecular formula of the compound and enter the appropriate subscript after each element.

1. Amylose is a "polysaccharide" that plants use to store energy. It is made of repeating subunits of C6H10O5.

a. A particular amylose molecule has 2113 of these subunits, what is its molecular formula? Express your answer as a chemical formula.

b. What is its molar mass? Express your answer to four significant figures and include the appropriate units.

c. What is the empirical formula for amylose? Express your answer as a chemical formula.

An organic compound contains C, H, N, and O. Combustion of 0.3069 g of the compound produces 0.8301 g CO2 and 0.2975 g H2O. A sample of 0.5322 g of the compound was analyzed for nitrogen. At STP, 30.54 mL of dry N2 (g) was obtained. In a third experiment, the density of the compound as a gas was found to be 3.68 g/L at 143 deg C and 244 torr. Calculate the empirical formula and the molecular formula of the compound.

The structure of the physicians service market has resulted in the development of the supplier-induced demand hypothesis to explain conduct in the market. In at least a 250 word posting, discuss the theoretical and empirical issues surrounding the supplier-induced demand hypothesis. After reading the postings of other students select the one that you found most interesting to respond to. Your response should be at least 75 words and include why you found this posting interesting.

The Acme Company manufactures widgets. The distribution of widget weights is approximately normal with a mean of 53 ounces and a standard deviation of 10 ounces. Use the Empirical Rule to answer the questions below. Sketch the distribution in order to answer these questions. (a) 99.7% of the widget weights lie between and (b) What percentage of the widget weights lie between 43 and 83 ounces? % (c) What percentage of the widget weights lie below 73 ? %

Question-1 Briefly sketch how Bohr derived the Rydberg’s empirical formula for atomic spectra using mix of classical mechanics and some ad hoc quantum assumptions. Indicate which steps in the derivation are motivated by classical mechanics and which are the quantum assumptions.

Question-2 Compute ionization energies of H, He+ and Li++ ions (Essentially all of them are one electron atoms) from ground state. Explain the trend.

The body temperatures of a group of healthy adults have a​ bell-shaped distribution with a mean of 98.08degreesF and a standard deviation of 0.63degreesF. Using the empirical​ rule, find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the​ mean, or between 97.45degreesF and 98.71degrees​F? b. What is the approximate percentage of healthy adults with body temperatures between 96.19degreesF and 99.97degrees​F?
