Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4 (SG = 1.139) and 60.0 wt% H2SO4 (SG = 1.498) are mixed to form a 4.00 molar solution (SG = 1.213).
(a) Calculate the mass fraction of sulfuric acid in the product solution.
(b) Taking 100 kg of the 20% feed solution as a basis, draw and label a flowchart of this process, labeling both masses and volumes, and do the degree-of-freedom analysis. Calculate the feed ratio (liters 20% solution/liter 60% solution)
Plot of the Fermi distribution function at two different temperatures. Calculate the Fermi timction at 6.5 eV if EF=6 .25 eV and T=300 K. Repeat for T=950 K assuming that the Fermi energy does not change. Plot the energy dependence of the ele..
Problem 1: For the circuit given in Figure 1 the power factor is 0.72 lagging and the power dissipated is 375 W.
In the hippopotamus, digestion occurs as an autocatalytic reaction in the stomach followed by a catalytic reaction in the intestines. This system can be modeled as a series of CSTR-PFR.
6. Famous New Zealand scientist Ernest Rutherford was awarded a Nobel Prize in which field? 7. What is the chemical symbol for gold? 8. K is the chemical symbol for which element?
The system works reasonably well, all things considered, except that Old Fred has a heavy hand and on the average breaks 30% of the 120 eggs that pass by him each minute. At the same time, a check of the "X-large" stream reveals a flow rate of 70..
