A 30.0 liter cylinder of a gas containing 97.0 mole% CO and 3.0% CO2 is delivered to your plant. The gauge on the tank reads 2000 psi. Several days later, the gauge reads 1875 psi, indicating a leak. The storage room in which the cylinder is kept has a volume of 24.2 m^3 and is poorly ventilated. Calculate the maximum mole% of CO in the room at the time the leak is discovered, assuming that the leaking gas spreads uniformly through the room and that the room temperature is constant at 30°C, using Kay's rule when appropriate.
If 199 atoms of bohrium-267 could be synthesized, how much time would elapse before only 11 atoms of bohrium-267 remain? What is the expected electron configuration of elemental bohrium?
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow

What is the best way to report density and absolute error in density based on the mass and volume measurements? Choose the single best answer 10.07 ± .194 gm/ml 10. ± .2 gm/ml
Mass of Air Required for Combustion of Fuel. A coal fired boiler uses fuel having the following analysis by mass:
Devise a control system for this reactor, and draw up a preliminary piping and instrument diagram. The following points need to be considered:
A certain gas has a molecular weight of 30.0 a critical temperature of 310K. and a critical pressure of 4.5MPa. Calculate the density in kg/m3 of this gas at 465 K and 9.0MPa
Are the following processes exothermic or endothermic? after selecting the answer please explain why you selected it. a. When solid KBr is dissolved in water, the solution gets colder.
Calculate the density of atoms along [011] in molybdenum (Mo). Express your answer in units of atoms/cm.
Make a rough estimate of the cost of steam per ton, produced from a packaged boiler. 10,000 kg per hour of steam are required at 15 bar. Natural gas will be used as the fuel, calorific value 39 MJ/m3 (roughly 1 MMBtu/1000 scf). Take the boiler eff..
The heat of formation of (NH4)2SO3 (aq) at 25°C is -890.0kJ/mol, and that of NH4HSO3 (aq) is -760 kJ/mol. The heat capacities of all liquid solutions may be taken to be 4.0 J/(g*°C) and that of the flue gas may be that of nitrogen. Evaporation of ..
