Consider a solution of Brz in CCI4. This solution will behave as an ideal dilute solution for low concentrations of Br2. The vapor pressure of CC14 is 33.85 torr at T= 298K. The Henry's law constant for the solution is 122.36 torr. The non-standard unit for the Henry's law constant is due to the concentration of Br2 being expressed as mole fraction. Calculate the following for a Xer2 = .07solution: a. Vapor pressure of CCI4. | b. Vapor pressure of Brz. c. Total pressure. d. Composition of the vapor phase.

Hybrid nanofluid Consist of mixed more than one nanopartical with working fluid such as CuO A1203, TiO2 with water and the Thermo physical properties of hybrid nanofluid depend on the type of nanoparticle. For example hybrid nanofluid consist of two of nanofluid Thermo physical properties of hybrid nanofluid Hybrid Nanofluid Phnf = Pfl = p;(1-42) [(1-4) + 4 (B;})] (PCp)nag = (PCp), (1—4₂) [(1–4₂) + 4, Hj Mined (1-01)25(1-02) 25 Ps +$2ps2 Kinf köf = (pcp)st (pcp)f ksz + (S-1)kbf-(S-1) ₂ (kbf-ksz) k2 +(S-1)ky + d₂ (kb-ksz) +$₂ (PCp) sz Where kbf_ks1 + (S-1)kg-(S-1) 1 (ky-ks1) ksi + (S−1)kƒ + ₁ (kj-ks1) = kf Example: evaluate the thermal conductivity of hybrid nanofluid consist of Cu, TiO2 ,H20, 9₁-0.02 for Cu, 9₁-0.03 for TiO₂ Density, specific heat and thermal conductivity of base fluids and nanoparticles H₂O Cu Properties/constituents 997.1 8933 Density, p (kg/m³) 4179 385 Specific heat, Cp (/kg K) Thermal conductivity, k (W/mK) 0.613 401 TiO₂ 4250 686.2 8.9538

2. How does the atomic arrangement in the CaF2 structure (as shown in the lecture material) differ from that of the NaCl structure?

What are the major differences (two differences) of “wide line NMR spectra” and “highresolution spectra”?

The activation energies for self-diffusion of tungsten (W), nickel (Ni) and lead (Pb) are640, 280 and 110 kJ/mol. Show that the relationship, Q ~ 20 R Tm, is a goodapproximation. Here R is the universal gas constant and Tm is the melting point.
