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.
(a) (i) Ksp value of Cul is 5.0 x10-12 mol2dm at 25 °C. Calculate the maximum number of moles of Cul that can be dissolved in 1 dm³ of water at 25 °C. (ii) Calculate the maximum number of moles of Cul that can be dissolved in 1 dm³ of 0.1 moldm³ of Nal solution at 25 °C.
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 a competitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Km of the enzyme was found to be 1.5 x 10-5 M. What is the Ki of the inhibitor?

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?
If the enzyme lactase has a Vo of 0.111111111111 mM per minute when [S] = 1.0 mM, and a Vo of 0.20 mM per minute when [S] = 5.0 mM, what is its Km? Calculate Vmax of the above enzyme (lactase). Calculate the slope on a Lineweaver-Burk plot (Km/Kmax) for the above enzyme (lactase).

Calculate the change in (total) CO, in the ocean surface mixed (Temp = 25C, Salinity = 35 ppt) layer if 1 nM of iron is added (and consumed), assuming it is indeed the limiting nutrient. %3D b. Would this change in total CO, affect the alkalinity of the surface ocean? Why/why not? c. How much would the pH of the surface change following this primary production (assuming no respiration/gas exchange)? Use pCO2 = 420 ppm and total alkalinity = 2.2 mM to start your calculations. %3D
You have a solution containing two metal cations. You want to separate them by slowly and carefully adding a solution of an anion, until one metal cation precipitates as a compound with that anion, leaving the other metal cation still in solution. Your metal cations (M+ and M2+) and your anion M+= Cu^+ M^2+= Cd^2+ Anion= S^2- First Ksp(M+ w/anion)= 2.5 x 10-48 Second Ksp(M2+ w/anion)= 1.0 x 10-28 ----------------------------------------------------------------------------------- Starting concentrations of yourmetal ions in your initial solution: [M+]= 4.00 x 10-5 M [M2+]= 2.50 x 10-5 M Using these values, predict which metal will precipitate first, and at what concentration of anion the precipitation will begin. Clearly state the parameters of your particular problem at the beginning. What is M+, what is M2+, what are your concentrations, what are you solving for?
In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K N,O;(g2 NO,(g) + % O2(g) the concentration of N2Og was followed as a function of time. It was found that a graph of In[N2O3] versus time in seconds gave a straight line with a slope of -6.96x10-3 s1 and a y-intercept of -1.41. Based on this plot, the reaction is order in N2Og and the rate constant for the reaction is s-!.
