You are trying to come up with a drug to inhibit the activity of an enzyme thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed an uncompetitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Vmax was determined to be 0.02 micromoles/min.mg. What is the Ki of the inhibitor?
What is the theoretical yield of ethyl chloride in the reaction of 20.2 gg of ethylene with 48 gg of hydrogen chloride? (For ethylene, MW=28.0amuMW=28.0amu; for hydrogen chloride, MW=36.5amuMW=36.5amu; for ethyl chloride, MW=64.5amuMW=64.5amu.)H2C=CH2+HCl→CH3CH2ClH2C=CH2+HCl→CH3CH2Cl
1) Commercial fuming Sulphuric acid (Oleum-H2S2O6) is 99.9% solution. Please convert it into molarity.2) Find out the Volume (dm3) of product (gas) at RTP when 0.58 M, 150 mL NaOH (aq.) reacts with 350 mL, 0.25 NH4Cl.
Some wastewater stream contains 0.015 M Hg22+. Some chemical engineer decides to remove it by precipitating it as Hg2CO3(s). He mixes 100.00 ml of the wasterwater with 100.00 ml of a 2.00 M solution of Na2CO3 and filters the result to remove the solid. How much residual Hg22+ should he expect to find still in the water? (Hint: it should not be 0) Ksp of. Hg2CO3 = 9.0 x 10-15. Also keep in mind that Hg+ is the only ion that exists in solutions as a dimer, i.e. Hg22+, not 2 Hg+ (Hg2CO3→ Hg22+ + CO32-)
10.5mL (mw 106) of benzaldehyde and 2.9g(3.63mL, mw 40) of acetone react with 5g of NaOH and 25mL of Ethanol to form 6.7g of Dibenzalacetone. What is the theoretical, actual and percent yield?

Receiving flask used during filtration was contaminated with HCl The Na2CO3 primary standard solution was overtitrated The saturated Ca(OH)2 solution was overtitrated Some Ca(OH)2 solid passed through the filter paper during filtration The water used to dissolve Ca(OH)2 solid was greater than the required amount
A wet pipette was used to transfer 10.00 mL of 1M HNO3 in the determination of ΔHrxn. [magnitude of ΔHrxn] In a maximum of 3 sentences explain why ΔHrxn decreases.
Chemistry The levels of an organic pollutant (P) in the groundwater at the perimeter of a plant were a cause for concern. A 10 mL sample of the water was taken and the pollutant was extracted with 95% efficiency using 25 mL of diethyl ether. GC was used to analyse the concentration of P in diethyl ether. A calibration curve was plotted for a series of standards of P which yielded the following results: Peak Area Toluene Conc. (µg/ml) 12,000 2.6 23,700 5.0 35,500 7.7 46,800 9.9 31,250 Sample Determine the concentration of P in ppb in the initial groundwater sample.
Potassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07
