Q

What is Grahams law?

A

The rate of diffusion of a gas across a membrane is inversely proportional to its total molecular mass and directly proportional to its solubility.

(Big stuff don’t fit in small holes. Larger gas molecules will take longer to diffuse across a membrane.)

Q

How do you tell the difference between cyanide and carbon monoxide poisoning?

A

Cyanide- produced by burning synthetics (carpet/plastics) can cause pulmonary edema.
CO- possible to be produced during combustion of most things, very likely in combustion of hydrocarbons. Should not produce pulmonary edema
