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 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…
An orange juice processing plant now produces essential oil from orange peels. one It is known that 250 kg of peel comes out of 1 ton of oranges and 2.5 g of essential oil comes out of 1 kg of peel. In a laboratory study, 250 g of bark was treated with hexane solvent and 0.548 g of essential oil was obtained in the sample cup of the rotary evaporator. Accordingly, the rotary Calculate the separation efficiency obtained in the evaporator?

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]
The %purity of a powdered crude sample of Na2CO3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr. a. How many moles of CO2 were collected? b. What is the percent purity of the sample? Round off to the nearest whole number

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.…
