• Can I work on a Ph.D without having neither a bacelor's or a master's degree?

I am interested on becoming a pediatrician and as you may know this is a very long career. I am a junior in college already. I was looking at the requirements for UM's medical school and they allow you to appy to their MD program after completing 90 credit hours. Now does anyone know if I can apply to their Ph.D program and earn an MD & Ph.D at the same time?

We did an experiment in lab where the concentration of one reactant stayed constant while the other varies. Here are the concentration in mL of each reactant:

Exp----------Oxalic Acid(H2C2O4)------------Permanganate (KMnO4)

---1------------ 5 ------------------------------------------- 1

---2------------ 10 -------------------------------------------1

---3-------------5 -------------------------------------------- 2

The reaction equation is:

3H2C2O4 + 2MnO4 --> 6CO2 + 2MnO2 + 2OH + 2H2O

Can someone please explain how to get the final concentrations of oxalic acid and permanganate?

• What is the concentration of CaCl2 in mass percent?

An aqueous CaCl2 solution has a vapor pressure of 81.2mmHg at 50 C. The vapor pressure of pure water at this temperature is 92.6 mmHg.

For this problem I keep solving it and getting 46.4%. Can anyone explain it?

• calculate the frequency of a photon emitted by a hydrogen atom when the electron falls from the n=10 energy le?

calculate the frequency of a photon emitted by a hydrogen atom when the electron falls from the n=10 energy level to the n=1 energy level

I know the answer is 3.26*10^15Hz

Can anyone explain what formula to use when calculating this

• Calculate the amount of 0.167 M phosphoric acid, H3PO4, that would be required to completely neutralize?

Calculate the amount of 0.167 M phosphoric acid, H3PO4, that would be required to completely neutralize 42.286mL of 0.325M sodium hydroxide.

I know that answer is 27.431mL

Can anyone explain how to get the answer.

• What is the molarity of ions in this solution?

a solution is created by dissolving 9.523grams of potassium permanganate,KMnO4, in water to a final volume of 52.9mL. What is the molarity of ions in this solution?

I know the answer to this is 2.28M, I'd like to know how to get to this answer. Which are the ions in this solution?

• Two dogs are mated. One of the parent dogs (P1) is long-haired (recessive allele). The litter which results?

Two dogs are mated. One of the parent dogs (P1) is long-haired (recessive allele). The litter which results contains two short-haired and three long-haired puppies (F1). What does the second parent (P1) look like, and what is its genotype?

idk if im getting the right answer I saw the second parent is

I tried using a punnet square to figure this out but I think the first parent is Ls and the second is Ss (l=long haired, s=short haired)

• Victor biked from his home town to a neighboring city in 5 hours?

Victor biked from his home town to a neighboring city in 5 hours. He biked back to his home town in 3 hrs. His speed on the return trip was 2 miles per hour faster than his speed on the first trip. How far apart are the two cities.

• Calculate the mass, in grams, of a single rubidium atom ( = 85.468 ).?

Calculate the mass, in grams, of a single rubidium atom ( = 85.468 ).

Can anyone please explain how to do this conversion?

I can get from grams to amu's but for some reason when I try the comversion backwards I don't get the right answe.

Thanks :)

• what does it mean when a car has dmv several records- 11 records ONE car?

I am interested in buying a car. The owner is suppose to be in the military in Span and the car is in Illinois stationed at the Scott base. She says she will have the car shipped directly to my house and a military personnel will com with all the papers required for the traspass of the title.

• Use the squeeze Law to show that...?

1. Limit as x goes to 0

x^2 sin(1+(1/x^2))=0

2. Limit as x goes to 1 (1+cos(1/x-1)) (x-1)^4=0

• Find the derivative of a tangent line y=(1/x)?

Please show me how to do thing the long way using the formula

M-tan = Lim as x--> x1 [(F(x)-f(x1)]/(x-x1)

Thank You :)

• Use the e (epsilon) - N definition to prove that Limit (2x-1)/(5x+2) = 2/5?

Please explain step by step how to solve thinks

• Find the derivative of f(x)= cubed root of (x) +1(the one is not inside the cubed root)?

Please use the long hand way of working it out. I know the answer is 1/3 x^(-2/3) but I found this by doing the short cut and I don't seem to get there the long way

Thank You
