- Why are adsorbate particles attracted and retained on the surface ofadsorbent?A well is drilled through a hydrocarbon-bearing formation which is at its irreducible water saturation and it has a porosity of 28%. Rock core data indicates that (a=0.81, m=2, and n=2). The mud used for drilling is water-base, with a salt concentration (NaCl) of 50,000 ppm. The connate water has a salt concentration (NaCl) of 20,000 ppm. The shallow and deep resistivity logs readings are 12 ohm-m and 50 Ohm-m respectively. You should assume that the deep resistivity tool will be sensing the virgin zone, which does not experience any mud-filtrate invasion, and that the shallow resistivity tool will be sensing the flushed zone. The formation temperature is 145° F. What is the hydrocarbon saturation of the formation and what is the water saturation in the flushed zone?Copper matte is charged into a silica lined converter in extraction of copper. What is the role of silica lining here?
- When plotted according to the linear form of the BET equation, data for the adsorption of N2 on Graphon at 77 K give an intercept of 0.005 and a slope of 1.5 (both in cm3 STP per gram). Calculate Asp assuming a molecular area of 16 (angstrom)2 for N2. Calculate also the heat of adsorption for the first layer (the heat of condensation for N2 is 1.3 kcal/mol). Would your answer for Vm be much different if the intercept were taken to be zero (and the slope the same)? Comment briefly on the practical significance of your calculation.Write down the flow chart of Hand molding process for the manufacturing of suppositories?

- A chemist received different mixtures for analysis with the statement that they contained NaOH, NaHCO3, Na2CO3, or compatible mixtures of these substances, together with inert material. From the data given, identify the respective materials, and calculate the percentage of each component. 1.000g samples and 0.2500N HCl were used in all cases. (A) For Sample W: With PP, 24.32ml was used. A duplicate sample required 48.64ml with MO. (B). For Sample X: The addition of PP caused no color change. With MO, 38.47ml of the acid was required. (C). For Sample Y: To cause a color change in the cold with PP, 15.29ml of the acid was necessary, and an additional 33.19ml was required for complete neutralization. (D) For Sample Z: The sample was titrated with acid until the pink of PP disappeared; this process required 39.96ml. On adding an excess of the acid, boiling, and titrating back with alkali, it was found that the alkali was exactly equivalent to the excess acid added.1.
