A given soil sample is subjected for proximate analysis - specifically moisture content and analysis of inorganic matter (or ash) content. A cleaned and tared crucible is weighed in an analytical balance and found to be 4.5015 grams . The soil sample is weighed-in and the crucible, together with the plant sample, measured a total of 6.2525 grams. The set-up is then placed in an oven and dried to 105 degrees Celsius for at least two hours. The setup is cooled to room temperature in a dessicator and then measured to a constant weight of 5.9775 grams. Afterwards, the setup is placed inside the muffle furnace and ignited to 720 degrees Celsius for at least an hour. The set-up is cooled to room temperature again inside the dessicator and then measured to the constant weight of 4.9375 grams. (A) What is the percent moisture in the plant sample? Write the answer in THREE SIGNIFICANT FIGURES. (B) What is the percent volatile (organic) matter in the plant sample? Express answer in THREE…
Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?
A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)
A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
If 35,000 kg of whole milk containing 4% fat is to be separated in a 6-hour period into skim milk with 0.45% fat and cream with 45% fat, what are the mass flow rates of the two output streams from a continuous centrifuge which accomplishes this separation? (Ans; Cream=464.8335kg/h, Skim milk= 5368.4998kg/h)
A spent sulfuric acid solution is brought up to strength for a pickling process in a mixer. Spent solution at 3% sulfuric acid (by weight) is mixed with a 50% solution (by weight) to obtain the desired product concentration of 40% acid by weight. All are aqueous solutions. Determine all flow rates on the basis of 100 lbm per hour of product. If the actual flow of the spent stream is 300 lbm per hour. What must the flow rates of the stream be?

An environmental study was performed to measure the transport of a DDT (a banned pesticide) throughout the globe. A lake in northern Canada was sampled to see if low levels of DDT were present there in spite of it not being administered within 1000 miles of that location. 1.000 L of the lake water was spiked with 100.0 uL of a 2.451 ug/L solution of tetrachlorobenzene, which acted as the internal standard. The entire 1.000 L spiked solution was concentrated onto an SPE column. After washing the SPE column with ~5 mL of pure water, the analyte and internal standard were eluted from the SPE column using ~5 mL of CH2Cl2 solvent. The eluted sample was evaporated under a stream of nitrogen to a final volume of 1.000 mL. 1 uL of this final solution was analyzed using GC-MS, and gave a signal of 24835 for DDT and 11597 for tetrachlorobenzene. To calculate the response factor, a standard solution was prepared consisting of 1.482 ug/L of DDT and 2.451 ug/L of tetrachlorobenzene.…
Amylum, commonly known as starch is a white powder with variable molecular formula due to the different number of repeating sugar units based on the plant that it is obtained from. A sample of amylum in the form of spherical beads was subjected to series of analyses to determine physicochemical properties in the quality control unit of a factory. From the results each bead is found to have a 4.5 mL volume and 1.47 g/mL density. 4 of the beads were placed in a reaction chamber combusted, as a result, 43.1 g CO2 and 14.7 g H2O were obtained. If the molecular weight of the amylum is 972.84 g/mol how many repeating units the starch molecule consist and what is the molecular formula of the starch? [Empirical Formula=CxHyOz, Repeating unit=n, Molecular Formula=( CxHyOz)*n= CnxHnyOnz]
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.)
