When 1.00 L of 2.00 M Na2SO4 solution at 30.0C is added to 2.00 L of 0.750 M Ba(NO3)2 solution at 30.0C in a calorimeter, a white solid (BaSO4) forms. The temperature of the mixture increases to 42.0C. Assuming that the specific heat capacity of the solution is 6.37 J/C g and that the density of the final solution is 2.00 g/mL, calculate the enthalpy change per mole of BaSO4 formed.
Propane in the feed to the unit and 80% of the pentane fed to the unit. The mole fraction of butane in the distillate is yB ? 0.4 . The bottom stream contains all of the hexane fed to the unit. Calculate the distillate and bottoms streams flow rate a..
Suppose that for mass transfer of species A from a fluid flowing over a flat plate the Schmidt number is much less than one (Sc
Design a sieve plate column to perform this separation, for a feed rate of 10,000 kg/hour. Treat the feed as a binary mixture of ethanol and water. Take the feed temperature as 20 °C. The column will operate at 1 atmosphere.
At Chernobyl in 1986, hydrogen was produced by the reaction of superheated steam with the graphite reactor core: C(s)+H2O(g) yields CO(g)+H2(g) It was not possible to prevent a chemical explosion at Chernobyl
Dry ice is placed in the bottom of a capillary tube 6.2 cm long. Air is blown across the top of the tube.
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum. The partition is rup..
A rigid container has water of 2 kg at 120 C with a quality of 25%. The container is heated to the temperature of 140 Celsius, calculate the new quality?
Ninety-five percent of the acetone vapour in an 85 vol.% air stream is to be absorbed by counter-current contact with pure water in a valve-tray column with an expected overall tray efficiency of 50 %.
A3m3 tank is divided into two parts via a thermally insulated wall. One part has a volume of 2 m3 and contains a vapor-liquid mixture of steam, 7% liquid, at 5 bar. The other part contains steam at 10 bar, 500 °C. A valve is opened and allows th..
Risk Analysis and Management: Earthquake - An example of Fragility and Load, The fully formated problem is with the solution.
In terms of heat treatment and the development of microstructure, what are two major limitations of the iron-iron carbide phase diagram?
