A piece of lead with a density of 11.3g/cm^3 and a mass of 7.45 grams is fired at a velocity of 385 m/s. Estimates the wavelength of the projectile.
When the generators supply a battery of emf 300 V and resistance of 1.5 Ω.
CHE 352 – Spring 2014, In this assignment, students will review some of the concepts of measurements discussed, 4 methods of measuring temperature, 4 methods of measuring fluid pressure
When the load is completely removed without change of excitation currents.
A fermentation reactor is charged with a sterile feed of growth media at 35 °C and inoculated with a batch of microorganisms. The batch is allowed to grow for 10 days. During the growth period the temperature is maintained at 37 °C by circulating ..
When concentrated H2SO4 is added to water, the solution gets very hot. d. Water is boiled in a teakettle
Why a substance is being heated at a fast rate the temperature of decomposition
You are requested to flash the mixture so that the liquid stream is 85% of the inlet (by mol). If the pressure is 1.5 bar, what temperature should be used?
A stream that contains a methanol/ethanol mixture with 32% mol methanol is flashed to 100 °C to a pressure such that the molar rate of the vapor stream is 75% of the feed. Determine the temperature and the composition of the two phases.
What is the pressure of the oxygen gas if the vapor pressure for water at 25°C is 23.8 mm Hg?
Calculate the equilibrium constant and the heat of reaction at 25 °C for this reaction. Is the reaction exothermic, or endothermic?
Again, much to the surprise of the student, it took only 5.00 mL of 0.020 M strong base to react completely with the HCl. Explain why it took only half as much strong base to react with all of the HCl.
The equilibrium constant should vary with temperature according to the relation Kp = ae-b/T use the results of part (b) to determine the values of a and b by a graphical curve-fitting procedure. [Suggestion: Use the spreadsheet program from part (..
