Unsaturated fats (oils) contain one or more double bonds that are chemically active. That makes them vulnerable to oxidation and to breaking of the long fatty acid chain at the double bond into shorter fatty acid chains. What does this tell you about the relative stability of ...

Bond breaking is an energy absorbing process. The question should read: "What is the amount of energy absorbed when a carbon carbon single bond is broken?" In a spontaneous decomposition, energy is released because of the formation of new, more stable bonds.

The melting point of PbCl2 is about 501 deg C. If the crystals melted, that would account for the increased conductivity. Impurities in the crystals could have lowered the melting point to 500 deg C. easily.

The reaction is: HCl + NaOH --> NaCl + H2O For 100% neutralization, moles NaOH needed is 3.75. For 50% neutralization, you use half of 3.75 millimoles NaOH. At that point, 50% of the HCl is still there. [H+] = conc. of HCl = (moles HCl)/(Total volume)* *Note: Total volume (...

Ka = [H3O^+][C3H5O3^- ] / [HC3H5O3] Let [H3O^+] = [C3H5O3^- ] = x Ka = [x][x ] / [conc. - x] (exact) Ka = [x][x ] / [conc.] (approximate if x is much smaller than cocnetration) I assume conc. = 0.0284 is moles/liter [H3O^+] = [C3H5O3^- ] = (0.067)(0.0284) Ka = {[(0.067)(0.0284...

pH + pOH = 14 pOH = 14-10.08 = 3.92 [OH-]=-log^-1(3.92)=1.2002x10^-4 --------- Kb = [BH+][OH-] / [B], with B = base here, Kb = [C17H21O4NH+][OH-] / [C17H21O4N] since [C17H21O4NH+]=[OH-] Kb = [OH-]^2 / {[C17H21O4N]-[OH-]} Since [OH-] is much smaller than the overall concentrati...

Here are the initial steps of the solution DrBob suggested: Let V = liters of solution. moles of H+ with pH 6 is = 1.00x10^-6)(V) The total moles of H+ in the mixture is: moles H+ = (1.00x10^-6)(V)+(1.00x10^-7)(V) [H+] = (moles H+)/V
