The Ka’s for H₂SeO₂ are K1 = 2.7 x 10^-3 K2 = 2.5 x 10^-7 Calculate the pH of a solution formed when 30.0 mL of 0.25 M KSeO3 is mixed with a) 1.5 mL of 0.20 M KOH b) 20.0 mL of 0.25 M HCl c) 25.0 mL of 0.20 M K₂SeO₃

I know how to calculate pH's however, I do not know when to use K1 vs K2, can you explain please?

Random samples of size n = 330 are taken from a population with p = 0.09.

a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p⎯⎯p¯ chart. (Round the value for the centerline to 2 decimal places and the values for the UCL and LCL to 3 decimal places.)

Centerline _________

Upper control limit __________

Lower control limit __________

b. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p⎯⎯p¯ chart if samples of 210 are used. (Round the value for the centerline to 2 decimal places and the values for the UCL and LCL to 3 decimal places.)

Centerline_____________

Upper control limit____________

Lower control limit____________

c. Discuss the effect of the sample size on the control limits. (fill in the blanks)

The control limits have a __________ spread with smaller sample sizes due to the _____________ standard error for the smaller sample size.

What is the role of the contemporary partisan think tank in U. S. politics and policy formation today? (250 words please)

Textbook publishers must estimate the sales of new​ (first-edition) books. The records indicate that 25​% of all new books sell more than​ projected, 30​% sell close to the number​ projected, and 45​% sell less than projected. Of those that sell more than​ projected, 55​% are revised for a second​ edition, as are 40​% of those that sell close to the number​ projected, and 25​% of those that sell less than projected.

a. What percentage of books published go to a second​ edition?

The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.3 minutes and a standard deviation of 2.2 minutes. Assume that the distribution of taxi and takeoff times is approximately normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway. (a) What is the probability that for 36 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Round your answer to four decimal places.) (b) What is the probability that for 36 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Round your answer to four decimal places.) (c) What is the probability that for 36 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (Round your answer to four decimal places.)

Calculate the molarity of the following solutions.

a) 0.950 mol of Na2S in 1.85 L of solution.

b) 30.9 g of MgS in 833 mL of solution.

___M

Cold air at a temperature of 10 C and a velocity of 3 m/s is moving parallel to a flat plate with a length of 6 m and a surface temperature of 75 C.

A) Find the transition location on the plate and the heat loss from the plate.

B) Repeat part (A) for water at the same velocity and temperature. The flat plate is made from copper.

A random sample of 12 steel ingots was taken from a production line. The masses. in kilograms, of these ingots are given below.

24.8 30.8 28.1 24.8 27.4 22.1

24.7 27.3 27.5 27.8 23.9 23.2

Assuming that this sample came from an underlying normal population, investigate the claim that its mean exceeds 25.0kg

LAC operon undergoes both negative and positive control of transcription initiation. Look over the structure of the Lac operon and its regulatory gene (LAC I).

a. Describe the negative control of this inducible operon. How does it prevent transcription initiation?

b. Describe the positive control of LAC operon. Include in your discussion, the CAP protein, adenlyl cyclase, and cAMP protein. How does it increase transcription to a higher rate?

c. In presence of glucose, inducer exclusion (keeping lactose out of the cell) is an important means of controlling transcription of the LAC operon. Phosphotranferase systems (PTS) of transporting sugars are essential to keeping the lactose transporter inactive until glucose is no longer available in the medium. Describe how the PTS is involved in both activating the lactose transporter and adenylyl cyclase in the absence of glucose?

2. Show that the first derivative of the the moment generating function of the geometric evaluated at 0 gives you the mean.

3. Let X be distributed as a geometric with a probability of success of 0.10.

a. Give a truncated histogram (obviously you cannot put the whole sample space on the x-axis of the histogram) of this random variable.

b. Give F(x)

c. Find the probability it takes 10 or more trials to get the first success.

d. Here is a challenge. What is the probability that it takes an even number of trials to get the first success, i.e., P(X=2,4,6,8,...)

the aldrich chemical company once manufactured a technical(low purity) grade of pinene that contained 85%(+)- alpha pinene and had a specific rotation of +43. is the 15% (by mass) impurity in this product more likely to be (-)-alpha-pinene, (-)-beta-pinene, or some optically inactive substance? justify your answer with calculations.
