Achemistry student accidentally drops a large mercury thermometer and it breaks. the thermometer contained 2 grams of mercury (hg), a potent neurotoxin. the hg leaks out and pools together into a droplet on the floor of the laboratory. the occupational safety and health administration (osha) sets the permissible exposure limit (pel) for mercury vapor in air at 12 parts per billion, by volume. at no time should anyone be exposed to mercury vapor above this threshold. the molar mass of hg is 201 g/mol. the temperature and pressure in the lab are 14.7 psia and 70°f, respectively.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
