Calculate the molarity of each of these solutions. a. A 5.623-g sample of NaHCO3 is dissolved in enough water to make 250.0 mL of solution. b. A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution.
Natural gas composed of 60. mol% methane, 30. mol% ethane, and 10. mol% propane at 25 °C and 500. psia is fed at a rate of 50. m3/hr into a boiler. In the boiler it is blended with enough air to provide 20% excess oxygen and combusted.
Explain the term "Selectivity" and "Yield".Selectivity is defined as the ratio of moles of desired product to moles of undesired product.Yield is defined as the ratio of moles of product formed to moles of reactant eitherfed or consumed and What a..
Test the knowledge and understanding of the concepts and procedures for process instrumentation and communication systems used in process industries.
Fresh halibut livers containing 25.7 wt % oil are to be extracted with pure ethyl ether to remove 95% of the oil in a countercurrent multistage leaching process. Calculate the amounts and compositions of the exit streams and the total number of the..
Carry out a sensitivity analysis on the adipic acid project described in Example 9.5. Investigate the sensitivity of the 10-year NPV to variation in total fixed capital (-20% to +50%), annual gross profit (-20% to +30%), and project construction s..
For removal of a heavy metal from a waste stream by electrodeposition, the electrolyte porosity is anticipated to decrease with time as determined by Faraday's law. For a Pb2+ present at 10mg/liter, given a flow rate of 100 liters/hour, how large mus..
The geometry and dimensions for a section of the blood vessel are shown on the right. Based on the Poiseuille's law the viscous resistance against blood flow through this section is determined to be 0.0002 mmHg•s/ml. If the diameter of the vessel ..
Calculate the equilibrium conversion, then redo parts (a) through (c) to achieve a concentration that is 90% of the calculated equilibrium conversion.
a discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and
About 1000 kg of leaf is required to produce 1 kg of the drug. The extraction solvent (S) is a mixture containing 16.5 wt% ethanol (E) and the balance water (W). The following process is carried out to extract the drug and recover the solvent.
Extract ore descriptors or features from the variables and design a model that can classify the ores correctly from images of the ore
