An absolute upper bound on G~ for stability of an equimolar binary mixture is GE = RT In 2. Develop this result. What is the corresponding bound for an equimolar mixture containing N species?
Show how each of the following strong electrolytes "breaks up" into its component ions upon dissolving in water by drawing molecular-level pictures. a. NaBr f. FeSO4 b. MgCl2 g. KMnO4 c. Al(NO3)3 h. HClO4 d. (NH4)2SO4 i. NH4C2H3O2 (ammonium acetat..
The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ
Caps are arranged on equilateral-triangle centers staggered perpendicular to direction of liquid flow, and liquid depth above caps is less than 1 in.
If the transmitted beam is reversed, so that it impinges on the interface from the glass side, calculate what the transmitted angle will be through the tissue. Does this make sense? Explain
Preliminary design work has been done on a process to recover a valuable product froman effluent gas stream. The gas will be scrubbed with a solvent in a packed column;the recovered product and solvent separated by distillation; and the solvent co..
(Note that the number of parallel paths is equal to the number of poles for lap windings.)
A liquid containing 60 mol% toluene and 40 mol% benzene is continuously distilled in a single-equilibrium-stage unit at atmospheric pressure. What percent of benzene in the feed leaves in the vapor if 90% of the toluene entering in the feed leaves..
If a 500-hp, 90% efficient synchronous motor, operating at full load and 0.8 leading power factor, is added instead of the capacitor in part (a), calculate the resulting power factor.
air at 4mpa and 3000c enters a will insulated turbine operating at steady state with negligible velocity. the air
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
Which of the following are requirements for anionic polymerization? A double bond End groups which can react by releasing a small molecule
Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, fol..
