Pentaborane-9, BsHs, is a colorless, high reactive liquid that will burst into flame or even explode when exposed to oxygen
The reaction is 2 BsH9()12 02(g)5 B0 (s)+9 H20 (I) Pentaborane-9 was considered as a potential rocket fuel in the 1950s because it produces a large amount of heat per gram. However, the solid B20s formed by the combustion of BsO is an abrasive that would quickly destroy the nozzle of the rocket, and so the idea was abandoned Calculate the kilojoules of heat released per gram of the compound reacted with oxygen.
The standard enthalpy of formation of BsH9 is 73.2 KJ/mol, B203is-1263.6 KJ/mol, and H20 is-285.8 KJ/mol
