We showed in lecture 8 that the Gibbs free energy of mixing a polymer of length X with a similar solvent of length 1 can be approximated as: Delta G_mix/M = Delta H_mix/M - T Delta S_mix/M = k_B T [phi_s phi_p chi_sp ln psi_s + psi_p/X ln phi_p] For a long chain polymer with large X, the final term becomes negligible. Consider a long-chain polymer in a monomer solvent, at an effective temperature of chi^-1 = 0.8. Determine the...

1. a) In the higher periods of the periodic table, there is more mixing between s and p orbitals. Without doing detailed calculations, it may not be clear whether Cl2 has “significant" mixing. Draw molecular orbital diagrams for this molecule (valence orbitals only!) for both the “significant mixing” and “insignificant mixing” cases. Can you distinguish which of these is the correct diagram based on magnetic properties of the molecule? Why or why not? b) Draw a molecular orbital energy diagram...

Gibb's energy of mixing is important in all areas of chemistry. Below is a protein mixing. A protein in its native (folded) state and a denatured (unfolded) protein are mixed. III mixing There are 0.002 moles of 75 mM folded protein and 0.006 moles of 75 mM unfolded protein. Upon mixing the moles of folded and unfolded protein remain the same. For this biochem example, determine AG mix. at T= 310 K. Report AG mix. in units of joules. -14.2...

In this lab, you will be breathing into a 5 L mixing chamber. The mixing chamber will start with “regular” air (20.93 vol% O2, 0.04 vol% CO2, and 79.03 vol% N2). You will inhale air through your nose (which is exposed to “regular” air) and exhale through your mouth into the mixing chamber. As your exhaled air is added into the chamber, an equal volume of air leaves the other end of the chamber so that the system remains at...

Mixing cost represents the costs of the spiced meat mixture transferred in from the Mixing Department. The spiced meat mixture is Orocessed in the Casing and Curing Department in batches; each unit in the above table is a batch and one batch of spiced meat mixture produces a set amount of sausages that are passed on to the Packaging Department. During September, 50 batches (i.e., units) were completed and transferred to the Packaging Department. Required: 1. Determine the Casing and...

October.
The Mixing Department of Best Foods had 65,000 units to account for in October. Of the 65,000 units, 35,000 units were completed and transferred to the next department, and 30,000 units were 40% complete. All of the materials are added at the beginning of the process. Conversion costs are added evenly throughout the mixing process and the company uses the weighted average method. Compute the total...

the mixing department performs a series
The Mixing Department performs a series of processes in which a fluid chemical is concentrated. Records indicate that the Mixing Department has been charged with $192,000 of direct labor costs. The manufacturing overhead rate is 150% of direct labor costs. Beginning work in process was $672,000 and ending work in process totaled $102,000. One-half of this period's completed products is sold on account at a price equal to 160% of its cost. Prepare journal...

A mixing chamber operates steadily at 200 kPa with 2 kg/s of saturated liquid H2O mixing with 1 kg/s of superheated steam at 250°C. Determine the exit specific enthalpy and exit temperature if the heat transfer rate into the mixing chamber is 150 kW throughout this process. Note: I know how to solve for the exit specific enthalpy, but I am not sure how to solve for the exit Tempurature. Could you please show me how to solve for the...
