18. Jet is an undergraduate chemistry student, he’s out in the laboratory trying to determine the volatile organic compounds as well as overall protein content of the leaf and stem of a malunggay (Moringa oleifera). He subjected the leaf and stem in a separate digestion reaction (treatment of sulfuric acid), afterwards he subjected the products to high temperature induction to get a dry ash like substance. Which type/s of chemical analysis did Jet employ to reach his objective?I. Qualitative AnalysisII. Quantitative Analysis III. Instrumental Chemical AnalysisIV. Wet Chemical AnalysisA. II & IV onlyB.

Compare and contrast an anticipatory standard to a reactionary standard by listing and describing some advantages and disadvantages.
a. Ethanol vapours were allowed to completely fill a large jug with a volume of 15.5L. The ethanol was burned yielding 5.5mL of pure liquid water in the bottom of the jug at the end of the reaction. C2H5OH + 3 O2 ? 2 CO2 + 3 H20 If the room temperature was 21.5 oC and the pressure was 0.996atm, calculate the percentage yield of the water gathered in the jug. b. A 10.0 mL sample of sulfuric acid with an unknown concentration was titrated with 3.5 x 10-4 mol/L NaOH. If 20.4mL of the sodium hydroxide was required to completely neutralize the acid, determine the concentration of the sulfuric acid in the sample. Then, determine the original pH of the sulfuric acid sample
Chemistry An aquifer contaminated with petroleum is found to have the following component concentrations at a particular site: benzene158 ppm toluene124 ppm ethylbenzene91 ppm xylene45 ppm n-heptadecane161 ppm pristane 84 ppm Provide an estimate for the age of the spill at this site using (a) BTEX ratio and (b) nC17:Pr ratio. Show your calculations and use units throughout. Give proper s.f. for the answer.
An aqueous waste stream that has a maximum concentrationof 0.50 M H₂SO₄ (d=1.030 g/mL at 25C) will be neutralized by controlled addition of 40% caustic soda (NaOH; d=1.430 g/L) before it goes to the process sewer and then to the chemical plant waste treatment facility. However, a safety re-view finds that the waste stream could meet a small stream of animmiscible organic compound, which could form a flammable vapor in air at 40.°C. The maximum temperature of the causticsoda and the waste stream is 31°C. Could the temperature in-crease due to the heat of neutralization cause the vapor to ex-plode? Assume the specific heat capacity of each solution is 4.184 J/gK.

In the synthesis of hydrocarbons, the carbon source is carbon dioxide. Although the CO2 concentra?on in the atmosphere raises at a drama?c speed, point sources are probably the easier sources for a PtX process.

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.
If all other variables were kept constant, determine theeffect that the following errors would have on the calculatedpercent yield of the product. Would the yield be expected toincrease, decrease, or would there be no effect? Explainyour reasoning.– The product was insufficiently dried before weighing.– Some of the product was lost during the transfer fromthe Buchner funnel to the evaporating dish.– 7.5 mL of FeCl3 was added instead of 3.0 mL asoutlined in the procedure.– 4.587g of K2C2O4H2O was used instead of exactly4.000g .– The recrystallization step was skipped and theexperiment went straight to vacuum filtration.
