unknown pre existing medical condition?


My kid has had stress fractures and pain since joining the Army 6 months ago.The Drs seem to have no clue why she isn't healing.There is some talk of fibromalgia.There was NO problem before she entered the service.If she is ultimately diagnosed with fibromalgia,is that a :pre existing"condition?At what point does it become the Army's deal?She had never been seen,diagnosed,or treated for this prior to joining.She may not even have it,but they are asking her if anyone in the family has fibromyalgia or rheumatoid arthritis.Is there a time limit in service where they cannot deny you benefits any longer?When there is no longer a "pre existing condition",but a condition that occurred during the service.I hope this is understandible.Thank you

Something similar happened to my son in the USMC. He is being sent home. They told him that he has developed Lymph edema. They is no family history of this on either side of our family. In his case, he is being told that once he heals, and with the proper medical waivers, he can reenlist but there is not military medical coverage for him. Contact your local Veteran's rep for more details, but the military feels that if the condition was preexisting, but the recruit was not aware of it, it's not their fault. Have her request copies of her medical records to bring home. Then take her to a civilian doctor and see if they can find out what's wrong. It's sad, but not all military doctors are the best or the brightest. Our military deserve the best medical care this country can offer, but that's not what they get. That's reserved for our President, Congressmen, and such...

Unknown Breathing Problems - Can't Burp - Synopsis

The rate of effusion of oxygen gas is twice the rate of effusion of an unknown gas under the same T and P?


The rate of effusion of oxygen gas is twice the rate of effusion of an unknown gas under the same conditions of temperature and pressure. What is the molar mass of the unknown gas? Enter your answer to 3 significant figures.

I can't even start this conceptually, let alone figure out the answer.

graham's law

http://en.wikipedia.org/wiki/Graham%27s_law

rate 1 / rate 2 = square root (molar mass 2 / molar mass1)

twice oxygen / rate oxygen = square root (32 g/mol / molar mass1)

2 = square root (32 g/mol / molar mass1)

square both sides:
4 = (32 g/mol / molar mass1)

molar mass 1 = 32 / 4

your answer is
8.00 g/mol
