A sample of enzyme involved in alcohol metabolism, extracted and purified extensively from yeast cultures, was loaded onto a gel filtration column for molecular weight approximation. A set of protein standards with known molecular weight was eluted separately through the same column and suitable buffer following the elution of blue dextran for void volume determination. The following table summarizes the data obtained from the experiment: Elution flow rate 1 mL/min Sample collector setting Continuous; Sequential Container change rate 1 tube/min Sample/Standard eluted Test tube No/s.

The researcher extracts a sample of well water and prepares it for TXRF analysis with a 10.00 mg/L V internal standard, like the calibration standards. The result produces SCa = 69297.81 and SV = 13481.2.Determine the concentration of Ca.
(c) The ore being placed on the heap has an average copper grade of 1.0% and the lixiviant addition rate is 900 m3 /hr. 5% of the liquid is lost through evaporation and other loses and the pregnant solution contains an average of 2.1 kg Cu/m³. The solvent extraction stage recovers 90% of this copper, with the barren solution having additional acid and water added to make up for the lost volume and consumed material before being added back onto the heap. What is the average recovery of the copper from the heap leaching assuming no losses in the SX/EW?

A potassium hydrogen phthalate solution was prepared by adding 0.0996 g of dry potassium hydrogen phthalate (MW = 204.22) in 100 mL distilled water. 1 mL of the prepared potassium hydrogen phthalate solution was transferred using pipette into 500-10000 mg/L COD tube before digested in the thermo-reactor at 148 oC for two hours. Calculate the measured COD reading in mg 02/L from the spectrophotometer at 600 nm if given oxygen molecular weight is 32 and the chemical equation for the oxidation reaction between potassium hydrogen phthalate (C8H5KO4) and chromic acid in the COD reagent tube is as follows: C8H5KO4 + 15/202 + H+ →→ 8C02 +K+ + 3H2O. (Note: MW is molecular weight)
Various parameters in a gas absorption experiment are as follows; Water flow rate =5 L/min, Air flow rate=25 L/min, CO2 flow rate=6 L/min. Then, to find the amount of CO2 absorbed into the water 1 hour after the system is started and stabilized, 50 mL samples are taken from the inlet and outlet of the tank and titrated with 0.01M NaOH. 100mL samples are taken from the tower entrance and exit and sent to the hemp apparatus. The consumptions measured with the help of the Hemp apparatus are 2.1 mL (inlet) and 1.9 mL (output), respectively. According to this, find the amount of CO2 absorbed by titration? (Note: The relative error in the experiment is 10.)

Wet air containing 4.0 mole% 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 3.40 kg. Following 5.0 hours of operation, the pellets are reweighed and found to have a mass of 3.54 kg. Calculate the molar flow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas. The mole fraction of water in the product gas is monitorced and found to have the valuc calculated in part (a) for the first 10 hours of operation, but then it begins to increase. What is the most likely cause of the increase? If the process continues to run, what will the mole fraction of water in the product gas eventually be?
