When boron hydrides burn in air, the reactions are very exothermic. B₁0H₁4 (8) burns in air giving B₂O3(s) and H₂O(g) in the reaction: B10H14 (s) + 11 O₂(g) → 5 B₂O3(s) + 7 H₂O(g) Calculate the enthalpy of combustion for B10H₁4 (8) (ΔfH' = -28.9 kJ/mol). The enthalpy of formation of B₂O3(s) and H₂O(g) are-1271.9 kJ/mol and -241.8 kJ/mol, respectively.
