The active ingredient in Benadryl Elixir is diphenhydramine hydrochloride, which slowly decomposes while on the shelf. The product should not be used if more than 10.% of the active ingredient has decomposed. If the product was prepared in November 2020 and the degradation process follows first-order kinetics with a half-life of 110 months, determine the expiration date that should be printed on the label of the product. (Report the answer to the month and year.)
