WebWAI Applications in Middle Ear Disorders in Children. WAI refers to a host of measures that assess the mechano-acoustical properties of the middle ear over a wide range of frequencies (e.g., 250–8,000 Hz) compared to conventional tympanometry, which assesses response to one or limited number of tones (e.g., 226 Hz, 1000 Hz). Weba) It exists as a mixture of +1 and +2 oxidation states. b) It exists as a mixture of +1 and 0 oxidation states. c) It exists as a mixture of +1 and +3 oxidation states. d) It exists as a mixture of +2 and +3 oxidation states. How would you determine the number of …
