Can I use this word like this: The addressal by the C.E.O. We are given the base dissociation constant, Kb, for Pyridine (C5H5N) which is 1.4x10^-9. This can be mathematically represented as \[\alpha = \dfrac{{{\Lambda _C}}}{{{\Lambda _0}}}\]. 0.0596 Which of the following indicates the most basic solution? potassium iodide dissolves in pure water Calculate the pH of a 0.065 M C5H5N (pyridine) solution. The Kb for pyridine is 1.9 10-9 and the equation of interest is CuS(s) + O2(g) Cu(s) + SO2(g) What is the hydronium ion concentration of an acid rain sample 2)The Kb for an amine is 5.438 * 10-5. 7. Es ridculo que t ______ (tener) un resfriado en verano. Since this sample has a total volume of #"1 L"#, the molarity of the two species will be, #["C"_5"H"_5"N"] = "0.10114 moles"/"1 L" = "0.10114 M"#, #["C"_5"H"_5"NH"^(+)] = "0.085670 moles"/"1 L" = "0.085670 M"#, Use the Henderson - Hasselbalch equation to find the pOH of the buffer, #"pOH" = - log(K_b) + log( (["C"_5"H"_5"NH"^(+)])/(["C"_5"H"_5"N"]))#, #"pOH" = -log(1.7 * 10^(-9)) + log( (0.085670 color(red)(cancel(color(black)("M"))))/(0.10114color(red)(cancel(color(black)("M")))))#, Since you know that at room temperature you have, #color(purple)(|bar(ul(color(white)(a/a)color(black)("pH " + " pOH" = 14)color(white)(a/a)|)))#, you can say that the pH of the solution will be equal to, #"pH" = 14 - 8.70 = color(green)(|bar(ul(color(white)(a/a)5.30color(white)(a/a)|)))#. An Hinglish word (Hindi/English). PLEASE HELP!!! 11.777 titration will require more moles of acid than base to reach the equivalence point. K(l) and I2(g) If initial concentrations are [SO2] = 6.00 M, [O2] = 0.45 M, and [SO3] = 9.00 M, the system is In this video we will describe the equation KClO4 + H2O and write what happens when KClO4 is dissolved in water.When KClO4 is dissolved in H2O (water) it wil.
