You 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?

Boranes are a class of chemical compounds that undergo combustion reactions that are very similar to the reactions of hydrocarbons but they release more heat. If they were not so expensive, they would be considered for rocket fuel. The structure of diborane is shown below. It “breaks rules” in terms of its Lewis structure. The “rule breaking” part is referred to as a “banana bond”. a) Explain why it breaks rules. b) Using the combustion of a hydrocarbon as your guide, predict the equation for the combustion of diborane. Balance the equation you predict.
