22. The new ACGIH TLV for Benzene is 0.02 ppm. The Assay Technology 525 badge has a 73.7m(l)/(m)in or 0.073 LPM uptake (sampling rate). The labs reporting limit for benzene is 0.001 mg . How long must you sample to get a detection limit less than the new limit of 0.02 ppm? 23. I want to collect a personal sample for respirable crystalline silica. List the sampling equipment, calibration equipment and media I need? 24. Respirable crystalline silica has a TLV of 25u(g)/(m)3. What is the highest air concentration of silica where a half-mask respirator will still protect a person? 25. What is the assigned protection factor (APF) for a Full-Face respirator?

In a calorimeter, you mix 50.0 mL of 0.100 molar AgNO₃ with 50.0 mL of 0.100 molar HCl. both of the solutions are originally at a temperature of 22.60 °C and the reaction mixture reaches a constant temperature of 23.40°C. The solutions react according to the reaction: AgNO₃ + HCl → AgCl + HNO₃ Use this date to calculate the enthalpy (∆H) for this reaction in kJ per mole of HCl consumed. You may assume that the combined solutions have a total mass of 100.0 g and a specific heat of 4.184 J/g°C.

(2) Do the previous part for t = 1.0 minute. (3) Using the results from parts (1) and (2), compute P{X(1.2) = C|X(0) = A} and P{X(3) = A|X(1) = B}. (4) Do part (2) for t = 5 minutes. What phenomenon have you observed? (5) Find the stationary distribution of the Markov chain. (Show all the steps)
