- Answze what you can see please they are mcqs and i dont have another picture of it mmake an effort pleaseGypsum (CaSO4) is one of common precipitants in brackish water desalination processes. CaSO4 ⇋ Ca2+ + SO42- Ksp = 10-4.6Assume a water containing: [Ca2+] = 10-2.1 M; [SO42-] = 10-3.2 M.(a) Find Qsp or IAP for the given water. (b) Find the solubility index (SI) and determine whether CaSO4 is under, super, or at saturation in the water.How to set up for problem 2
- Use E5C.1(a) to Plot the data in excel. Place two data sets on the same graph: one for temp vs. x and one for temp vs y (remember, x and y are the mole fractions and they belong on the x-axis). Don’t forget to include the boiling points of the pure substances – they are data, too. Add a trendline (polynomial, 3rd order should work) to each of the coexistence lines separately. Scale the plot appropriately and use the graph to answer the questions. Then complete E5C.1(b)(a) Water in vadose zone contains chlorobenzene of concentration 40 mg/L. What is the equilibrium concentration soil air in contact with this solution? (b) An aquifer with porosity 0.3 has distribution coefficient of TCE as 100 L/kg. What fraction of TCE is in aqueous phase and sorbed phase of the soil?Show all steps leading to the final answer po.

- please help this is my 4th time posting this and i havent gotten a correct answer. Please actually draw the graph out. A newly discovered enzyme, MBCase, cleaves carbon-carbon bonds of vicinal alcohol; The kinetic parameters were measured for 1.0 nM Of MBGase and determined to be a Km = 10 nM and a kcat = 100 s-1 a.) Sketch the graph out as a double-reciprocal plot (Lineweaver-Burke Plot) and label: -the axes (with units) -the point on the curve that can be used to determine Km -the point on the curve that can be used to determine VmaxHexanoic acid was added to an immiscible biphasic solvent sysem, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D1) of hexanoic acid in CCl4 with respect to water.Please answer atleast 4 sub-parts. Thank you.
