Binary gas separation membrane [40 pts]: a hollow-fiber asymmetric polymeric membrane is considered for splitting a 88% h2 (balance n2) stream into high-purity and mid-purity h2 streams. the asymmetric fiber has a dense, functional film thickness of 20nm and a permeability of 70 barrer and a h2: n2 permselectivity of 25: 1. there is negligible mass transfer resistance outside of this dense, functional film thickness. the system internals are uniquely designed such that both the retentate and permeate volumes are well-mixed. (1 barrer = 3.35x10-16 mol/s/m/pa). the retentate pressure is maintained at 60psia and the permeate pressure is at 15psia. gas mixture is supplied to the membrane at a flowrate of 5 kmol/hr. a. [5 pts] what is the maximum possible hydrogen purity that can be achieved using this unit? b. [20 pts] if the target rejected stream composition (xo) is 0.75, what is the permeate composition and flowrate, and what is the membrane surface area required? c. [15 pts] what are the permeate and retentate outlet h2 mol% for a ‘cut’ of 0.58? note: 14.696 psi = 1 atm = 101325 pa = 101.325 kpa = 1.01325 bar

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
