A 45.00 -mL sample contains 0.754 g of KHC₈H₄O₄, known as KHP . This sample is used to standardize an NaOH solution. At the equivalence point, 43.30 mL of NaOH have been added.

K_a( HC₈H₄O₄^-) = 3.9E-6

a) What was the concentration of the NaOH?

b) What is the pH at the equivalence point?

China is currently rising and is slowly become a world power.

Various factors or forces impact a company’s decision to go into a foreign market and affect the outcome of that decision. If a country or market has several factors in common with the original market, or with the other markets selected when choosing several markets, it will be easier to enter that market.

A hollow aluminum cylinder 23.5 cm deep has an internal capacity of 2.000 L at 17.0°C. It is completely filled with turpentine at 17.0°C. The turpentine and the aluminum cylinder are then slowly warmed together to 75.0°C. (The average linear expansion coefficient for aluminum is 24 ✕ 10−6°C−1, and the average volume expansion coefficient for turpentine is 9.0 ✕ 10−4°C−1.)

(a) How much turpentine overflows? cm3

(b) What is the volume of turpentine remaining in the cylinder at 75.0°C? (Give your answer to at least four significant figures.) L

(c) If the combination with this amount of turpentine is then cooled back to 17.0°C, how far below the cylinder's rim does the turpentine's surface recede?

9.The Federal Reserve System regulates the money supply primarily by

A.restricting the issuance of Federal Reserve Notes.

B.controlling the production of coins at the United States mint.

C.varying the reserves of banks, largely through sales and purchases of government bonds.

D.altering the reserve requirements of banks and thereby the ability of banks to make loans.

Which of the following statements about the Federal Reserve is (are) correct?

(x) When the Federal Reserve conducts open market transactions, it buys or sells government bonds from the public and these actions allow the Fed to control the level of reserves in the banking system.

(y)In general, if the Fed bought a bond from a bank via the open market, then the bank’s excess reserves would increase and the money supply would increase if the bank loans out all of its excess reserves.

(z)If the Fed buys government bonds then the money supply will eventually decrease.

A.(x), (y), and (z)B.(x) and (y) onlyC.(x) and (z) onlyD.(y) and (z) onlyE.(x) only

1. How does the Bordeaux wine distribution system work? Who benefits and how?

2. How is price set? Trace the process from the sale of the first tranche to the sale of a bottle in a wine store for $1,200. Why is the process so complicated?

Using implicit Intents, you are to write a complete Android application, using menus or BottomNavigationView to

1. Allow the user to send SMS messages to multiple users at the same time.
2. Allow the user to send E-mail to multiple users including CC and BCC
3. Allow the user to Locate any specific place on Google Map by either

specifying a detailed information about a location or by specifying Latitude and longitude coordinates

4. Take a picture.

Impress me lots lots lots with this application.

Your are free to add whatever to need or wish.

Enjoy!

If I want to show an exception in JAVA GUI that checks if the date format is correct or the date doesn't exist, and if no input is put in how do I do that. For example if the date format should be 01-11-2020, and user inputs 11/01/2020 inside the jTextField it will show an error exception message that format is wrong, and if the user inputs an invalid date, it will print that the date is invlaid, and if the user puts no value inside the text box, it willl print an exception message that there needs to be a value. Please help.

is it necessary for police officers to have psychological testing? Why or why not?

Left ventricular mass (LVM) is an important risk factor for subsequent cardiovascular disease. A study is proposed to assess the relationship between childhood blood pressure levels and LVM in children as determined from echocardiograms. The goal is to stratify children into a normal bp group (< 80th percentile for their age, gender, and height) and an elevated bp group (≥ 90th percentile for their age, gender, and height) and compare change in LVM between the 2 groups. Before this can be done, one needs to demonstrate that LVM actually changes in children over a 4-year period.

To help plan the main study, a pilot study is conducted where echocardiograms are obtained from 10 random children from the Bogalusa Heart Study at baseline and after 4 years of follow-up.

Implement an appropriate 2-sided test to test the hypothesis that there is a change in mean LVM over 4 years?

You must clearly write out all 4 steps of the appropriate hypothesis test clearly defining the parameter(s) involved, calculate the value of the test statistic and the p-value, and state your conclusion in the context of the problem.

3. (a) California Bank holds $375 million in deposits and maintains a reserve ratio of 5%. Show the T-account of the bank
