Determine the mass in grams of sodium dihydrogen phosphate (NaH2PO4.H2O) and disodium hydrogen phosphate (Na2HPO4) needed to prepare 1 L of a standard buffer at pH 7.00 with a total phosphate concentration of 0.100 M. You should write the chemical equation for the reaction (equilibrium).

A 1.0 M solution of a compound with 2 ionizable groups (pKa’s = 6.2 and 9.5; 100 mL total) has a pH of 6.8. If a biochemist adds 60 mL of 1.0 M HCl to this soluion, the soluion will change to pH?

1. A 1.0 M solution of a compound with three ionizable groups (pKa’s = 2.3, 6.7 and 9.5; 100 mL total) hasa pH of 7.1. If a biochemist adds 60 mL of 1.0 M HCl to this solution, what is the new pH of the solution?

2.Determine the mass in grams of sodium dihydrogen phosphate (NaH2PO4.H2O) and disodium hydrogenphosphate (Na2HPO4) needed to prepare 1 L of a standard buffer at pH 7.00 with a total phosphateconcentration of 0.100 M. You should write the chemical equation for the reaction (equilibrium).

1. Determine the weight in grams of sodium dihydrogen phosphate (NaH2PO4.H2O) and disodium hydrogen phosphate (Na2HPO4) needed to prepare I L of a standard buffer at pH 7.00 with a total phosphate concentration of 0.1 M. (pKa of dihydrogen phosphate = 6.86).

1. An asset manager anticipates the receipt of funds in 200days, which he will use to purchase a particular stock. The stock he had in mind is currently selling for P62.50 and will pay a P0.755 dividend in 50 days and another P0.75 dividend in 140 days. The risk free rate is 4.2%. The manager decides to commit to a future purchase of stock by going long a forward contract on the stock.
   REQUIRED:
   At what price would the manager commit to purchase the stock in 200 days through a forward contract?          (5 marks)
   Suppose the manager enters into the contract at the price you found in Part a. Now, 75 days later, the stock price is P55.75. Determine the value of the forward contract at this point.                       (5 marks)
   It is now the expiration day, and the stock price is P58.50. Determine the value of the forward contract at this time.         (5 marks)

3. Be sure to include a Works Cited Page for the following draft .

Please do not simply list how the Home life, School life, or Community affects a student.

the following table below shows a column for Year, Nominal GDP, Price Index and Real GDP. fill in the Blank spaces for Nominal GDP, Real GDP and the Price Index using the formula for computing Real GDP.

Year Nominal GDP, Billions Price Index (2005=100) Real GDP, Billions

1968 Nominal GDP, Billions $909.8 Price Index 22.01 Real GDP, Billions

1978 Nominal GDP, Billions $2,293.8 Real GDP, Billions 5,677.72

1988 Nominal GDP, Billions 5,100.4 Price Index 66.98 Real GDP, Billions 7,614.81

1998 Price index 85.51 Real GDP, Billions 10,283.59

2008 Nominal GDP, Billions 14,441.4 Price Index 108.48 Real GDP, Billions

GDP and price index concepts have been a challenge for me to grasp. 

Based on the readings that concentrate on mercantilism, the Triangle Trade, slave plantations in the colonies, and the effects of the Enlightenment on society. Respond this question in one or two pages:

1. According to Eric Williams, the West Indies' plantation slavery (note that slavery is a form of command economy) played a role in England's transition to a market economy. Keep in mind that most people in England lived as farmers, who were essentially independent of the market, before slavery spread to the Caribbean plantations.

For this assignment, name two and thoroughly explain how slavery helped nurture a shift to the market fixing the economic crisis in England, despite the fact that Williams develops a number of reasons surrounding this.To put it another way, how did slavery in the Caribbean: help create more wage labor in England; more goods for sale; more monetary revenues; or other things necessary for the market to address the economic problem

For the 1st five hours of the day, the arrival rate at the brand new book store is 35 customers per hour. The book store is capable of serving 30 customers per hour. The last customers arrives exactly five hours after the start of the day. Let us assume that the system is empty at the start and that no customer who arrives leaves without being served.

How long will that customer be in the book store (in hours)

For your Advanced Evolution class, you need to design an experiment that will test for group selection. You have a greenhouse with 900 Arabidopsis thaliana plants and a fat wallet to pay for your experiment. Describe the experiment you would conduct, making sure to explain i) what trait you would select for, ii) how you would do the selection, and iii) what you would expect the results to look like if you found evidence of group selection. But don’t select on population size, that’s already been done!
