I have a take home test. The most commonly fractured is the clavicle, but it only gave trapeziium, phalanx, scaphoid, and metacarpal. The scaphoid is the most commonly injured of the carpal bones, I think maybe phalanx cause there is so many, but im not sure...

Many biochemical reactions that occur in cells require relatively high concentrations of potassium ion (K+). The concentration of K+ in muscle cells is about 0.15 M. The concentration of K+ in blood plasma is about 0.0050 M. The high internal concentration in cells is maintained by pumping K+ from the plasma. How much work must be done to transport 1.0 mol K+ from the blood to the inside of a muscle cell at 37°C, normal body temperature?

When 1.0 mol K+ is transferred from blood to the cells, why do other ions have to be transported?

Given

HNO3 + KOH --> KNO3 (aq he) + H20

the heat gained by the calorimeter and the heat of the reaction (assume the density and the specific heat are the same as distilled water):

Temp of 50.0 mL of HNO3 before mixing : 22.0 degrees Celsius

Temp of 50.0 mL of KOH before mixing : 22.0 degrees Celsius

Temp of 100.0 mL of reaction mixture : 34.5 degrees Celsius

how many joules are gained my the solution, how many joules are gained by the calorimeter and what is the heat of reaction?

Use these date to calculate the molar mass of an unknown volatile liquid. (this is all i was given)

Initial mass of empty flask and top= 86.8234 g

Final mass of flask, top and condensed liquid= 87.7431 g

Flask Volume= 274.0 mL

Barometric Pressure= 741.6 torr

Temperature= 99 C

What is the Molar Mass?

like i participate in 3 sports, and i get hurt and can deal with it. i have had tons of sprains and bruise etc... yet i cut my thumb with a knife (less than an inch) and fainted... and i fainted when i got my cartilage pierced... its not like i was in pain, hell i barely felt it... but i still faint. WHY?!?!?

oh and i can totally stare at and fix others peoples cuts with no issues too... so its not the sight of blood....

i know that it isnt the ventricles contracting because the waves themselves arent caused by that, i think it has something to do with the SA node maybe???

from her song perfect... i find this line so captivating, but i cant figure out exactly what it means.

or close to you. serious responses only please...

so i was using this machine http://s3.hubimg.com/u/2775218_f520.jpg and i did 12 reps and added more weight to do another set, after a few at the greater weight my knee started to kinda click as i went down (when my leg was like a 75 degree angle), it kinda hurt but i wanted to finish out so i kept going and the continual clicking got more painful so i stopped.

long story short i have been walking on it all day and it hasn't stopped hurting. its a sharp shooting pain on the outside of my left knee. mostly it hurts going down steep hills, up hills and stairs and also when im walking (but not as bad walking as stair). even just sitting there is a dull ache

i just couldn't go one more minute, i felt like i needed to breathe in deeper but i couldn't :( but im so close! :) encouragement is always welcomes :D

it also had the date 1958, idk if that is relevant or not, but what do you think it means and why? and why on the chimney?

i dont remember the lyrics at all. :( help me?

little example... team a plays team b... at what point does team a decide that they are winning by a super lot and pull off the full court press they have been using all game? when should they put in the bench and say its time to lay off a bit?

the slope of a strictly monotonic function f is 4/9 at a particular point (a,b) what is the slope of f^-1 at the point (b,a)?

f^-1 means inverse
