- 1arrow_forwardYou will not find “hydroxide” in the stockroom, but you will find sodium hydroxide (NaOH) andpotassium hydroxide (KOH). Lithium hydroxide (LiOH) is expensive and used in spacecraft airfilters since hydroxide reacts with carbon dioxide, and lithium is lighter than sodium or potassium.Cesium and francium hydroxides are very expensive and little used. Is this information consistentwith your answer to the previous question?arrow_forwardDraw a second resonance structure for each species in parts (a), (b), and (c). Draw two additional resonance structures for the ion in part (d).arrow_forward
