Photoionization processes (e. g., N2 + hν → N2+ + e–) remove UV light with λ <150 nm. Which photoreaction is the principal absorber of UV light in the 150-200 nm range in the upper atmosphere? N2 + hν → 2N O3 + hν → O2 + O O2 + hν → 2O NO + O2 + hν → NO3 N2 + O2 + hν → 2NO

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
