In order to wash out the impurity, you looked up some sketchy method from 1952 which Hank Pym wrote during his Ph. D. under E. J. Corey. The method requires you add HCl to the mixture. After you rid your sample of any impurities, you take some pH paper and find out your solution has a pH of 3.0. Assuming the pKa of Pym Particles is 4.5 and that the molar absorptivity of the protonated Pym Particle is 4.82 * 102 L/mol*cm and 8.54 * 103 L/mol*cm for 400 nm and 690 nm respectively, calculate the expected A400 and A690 of the solution.

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
