RDC 5006:  This standard requires that all containers holding hazardous chemicals be labeled, tagged, or marked and that all warnings be listed. It helps process technicians understand the chemicals they encounter, their hazards, and why certain precautions must be taken on the job. What is the [name] of the standard? Choose from the list below: Type in the initials in bold. NAPTA = North American Process Technology Alliance PTO = Parent Teachers Organization HAZCOM = Hazardous Communication FE = Fugitive Emissions SARA = Superfund Amendments and Reauthorization Act

Carbon dioxide behavior is in good agreement with Van der Waals state equation with the following parameters: a = 3.658  x 105 Pa  L2  / mol2b = 4.29 x 10-2  L  / mol.   Now assume that we have 10 grams of carbon dioxide inside a cylinder of volume 100 cm3.   (Note: atomic weight of 1 mole of C is 12.01 , and for O it is 16.00). A) Assuming the carbon dioxide behaves as ideal gas, calculate its pressure in Pascals at temperature 25 Celsius degrees. Then calculate its pressure at the same temperature using Van der Waals equation of state. Based on the results, do you think ideal gas behavior is an accurate approximation? B) Now repeat the pressure calculations again, but this time at 250 Celsius degrees. In such a case, is ideal gas behavior a better approximation for carbon dioxide than at lower temperature? C) Now consider again carbon dioxide, at 25 Celsius degrees. This time the container volume is 10000 cm3. How does the prediction of ideal gas pressure compare to pressure calculated with Van der Waals equation? What can you say about how does the agreement between Van der Waals gas and the ideal gas behavior when we increase / decrease the volume while keeping the temperature the same?

Given: The enthalpy of fusion of propanol (C4H10O) is 8.4 kJ/mol. ln(A), from the Clausius-Clapeyron equation, of propanol is 3.1 (unitless). What is the vapor pressure (NOT ln(P)) of propanol at 267 K? Answer in atm. Do not type units. Do not use scientific notation.
