Consider the following equation for the production of NO2 from NO:2 NO(g) + 02(g) ------> 2 NO2(g)a. If 84.8 L of 02(g), measured at 35C and 632mm Hg, is allowed to react with 158.2 g of NO, find the limiting reagent.b. If 97.3 L of NO2 forms, measured at 35C and 632mm Hg, what is the percent yield?
Calculate the percent ionization of 0.00340 M hydrocyanic acid (Ka = 4.9e-10). % ionization = % (b) Calculate the percent ionization of 0.00340 M hydrocyanic acid in a solution containing 0.0220 M sodium cyanide. % ionization = %
