Question: Diborane (B 2 H 6 ) is a highly reactive boron hydride that was once considered as a possible rocket fuel for the U.S. space

Diborane (B2H6) is a highly reactive boron hydride that was once considered as a possible rocket fuel for the U.S. space program. Calculate ΔH for the synthesis of diborane from its elements, according to the equation

2B(s) + 3H(g) - BH6(g)

using the following data:

Reaction (a) 2B(s) + O(g)  BO3(s) (b) BH,(g) (c) H(g) + (d) HO(l) + 30(g) O(g)  HO(l) HO(g) BO3(s) + 3HO(g)

2B(s) + 3H(g) - BH6(g)
