WebReaction of diborane with ammonia mainly gives the diammoniate salt [H 2 B(NH 3) 2] + (BH 4) −. Ammonia borane is the main product when an adduct of borane is employed in place of diborane: BH 3 + NH 3 → BH 3 NH 3 + THF Properties and structure. The molecule adopts a structure similar to that of ethane, with which it is isoelectronic WebThe compound diborane (B2H6) is used as a rocket fuel. The equation for the combustion of diborane is shown below. Use Hess’s law to calculate the enthalpy of combustion of …

Diborane and its monomeric adducts borane–tetrahydrofuran or borane–dimethylsulfide are useful reagents. They are often used for hydroboration in organic synthesis. Some higher boranes, including anti-B18H22, have demonstrated luminescent properties. Some cobalt derivative of carboranes have been commercialized for sequestering Cs from radioactive waste. Because boron hydride clusters readily absorb neutrons, their derivatives have often been inves… WebA bomb calorimeter can be used to measure the enthalpy of reaction for combustions, What is the final temperature of the calorimeter? such as the combustion of diborane represented by the following balanced equation: Assume that 0.291 g of diborane is combusted in a calorimeter whose heat capacity (C calorimeter) is 7.854 kJ/°C at 26.25°C. tempat merebus air
