Question

An acidic solution at 25 degree C has [H_3O^+] > [OH^-] > 1 Times 10^7 M [H_3O^+] > Times 10^7 M > [OH^-] [H_3O^+] = [OH^-] > 1 Times 10^7 M [H_3O^+] [OH^-] What is the strongest monoprotic acid of the following set if all the acids at the acids are at 0100 concentration? hydrofluoric acid with K_a = 3.5 Times 10^-4 benzoic acid with K_a = 6.5 Times 10^-5 acetic acid with K_a = 1.8 Times 10^-5 hypoclorous acid with K_a = 3.5 Times 10^-6 What is the common ion in a solution prepared by mixing 0.10 M NaCH_3CO_2H? H_3O^+ Na^+ CH_3CO^-_2 OH^- What is the most soluble salt inthe following Ba(OH)_2 with K_sp = 5.0 Times 10^-3 Ca(OH)_2 with K_sp = 4.7 Times 10^-6 Cd(OH)_2 with K_sp = 5.3 Times 10^-15 Fe(OH)_2 with K_sp = 2.5 Times 10^-37 Sodium hypoclorite, NaOCl, is the active ingredient household bleach, What is the concentration of hypocholoride ion if 20.00 ml. of bleach requires 28.30 mL of 0.500M HCL to reach the equivalence point? 0.208M 0.353 M 0.708 M 1.21 M K_p is related to K_c by by the equation K_p = K_c(RT)^n. What is the value of the reaction below? NH_4NO_3(s) rightarrow N_2O(g) + 2H_2O9g) + 2H_2O(g) -2 -1 +1 +2 Give the reaction at a certine temperature: 2Hl(g) rightarrow H_2(g) + I_2(g). At equilibrium, the partial pressure of HI is 108 Times 10^-3 atm. and the partial pressure for H_2 are I_2 are 0.10 atm each. Find K_p at that temperature 3.2 Times 10^-4 5.6 Times 10^1 3.1 Times 10^3 3.1 Times 10^4
