Consider the titration of 35.0 ml sample of 0.175 M Her with 0.200 M KOH. Determine the quantities below:
Equation of reaction:HBr(aq)+KOH(aq)<>KBr(aq)+H2O(l)
a) initial oh, before the addition of base
b) ph at 10.00ml added base
c) pH at equivalent point
d) ph after adding 35.00 ml of base

1. Assume that labor demand elasticity < 0 and labor supply elasticity > 0 but small. Explain in words and use a labor market diagram to show the effects of immigration on the receiving country’s
   1. GDP
   2. Number of native workers
   3. Labor income of native workers
   4. Number of immigrants
   5. Labor income of immigrants
   6. Total number of workers
   7. Wage rates before and after immigration
   8. Income of capitalists/consumers

The Dakota Corporation had a 2015 taxable income of $17,000,000 from operations after all operating costs but before (1) interest charges of $3,500,000, (2) dividends received of $290,000, (3) dividends paid of $2,050,000, and (4) income taxes.

a. Use the tax schedule in Table 2.3 to calculate Dakota’s income tax liability. (Round your answer to the nearest dollar amount.)

Assume a corporate tax rate is 40% and an individual tax rate of 25%. Perryton Corp. earned $12,000,000 before income taxes during the year. Perryton kept $5,000,000 of after-tax profits inside the company to support future growth. How much total tax would have been paid to Internal Revue Service (IRS) by all related parties?

Assume that a wave of immigration increases a country's labor force but does not affect its capital stock. Use the Solow growth model to explain your answers with the corresponding graph.  

a. What is the immediate impact of the immigration wave on total output and on output per person?

b. Is the growth rate of output per worker after the immigration wave smaller or greater than it was before?

Garden Industries can sell 15-year, $1,000 par value bonds paying annual interest at a 12% coupon rate. The bonds can be sold for $1010 each, flotation costs of $25 per bond. The firm is in the 40% tax bracket.

​a. Find the net proceeds from sale of the bond Nd

​b. Calculate the before-tax and after-tax costs of debt.

Supermarket shoppers were observed and questioned immediately after putting an item in their cart. Of a random sample of 290 choosing a product at the regular price, 210 claimed to check the price before putting the item in their cart. Of an independent random sample of 210 choosing a product at a special price, 161 made this claim. Find a 95% confidence interval for the difference between the two population proportions.

●Explain when randomization is not possible because of ethical or practical reasons

●Understand why estimating the counterfactual is more problematic without randomization

●Describe basic strengths and weaknesses of common observational approaches to estimatingcounterfactuals, such as before-after designs, simultaneous control groups, and combined designs.

●Understand the importance of identifying causal mechanisms and theory for making causal inferences innon-randomized studies.
