Consider the reaction \rm CO(g) + NH_3(g) \rightleftharpoons HCONH_2(g),~~~~{\it K}_c=0.860 If a reaction vessel initially contains only \rm CO and \rm NH_3 at concentrations of 1.00 M and 2.00 M, respectively, what will the concentration of \rm HCONH_2 be at equilibrium?
Calculate the concentration of SCN- present in the Hg22+/Cu+ solution when the first (initial) cation begins to precipitate, and the concentration of SCN- present in this solution when the second (final) cation begins to precipitate
if the level of solution in the column drops below the level of the resin, channels will be formed in the resin column.How will this influence the efficiency of ion exchange in the column?
Benozoic Acid has a Ka = 6.3*10^-5. A 35.0mL sample of 0.130 M Benzoic Acid is titrated with 0.150M NaOH solution. Find the pH after 0.0mL NaOH is added.
