Pentaborane B₅H₉(s)burns Vigorously in O₂ to Give B₂O₃(s)and H₂O(l) $\Delta$ H°_rxn for the Combustion of 1 Mol of B₅H₉

Pentaborane B₅H₉(s) burns vigorously in O₂ to give B₂O₃(s) and H₂O(l) .Calculate $\Delta$ H°_rxn for the combustion of 1 mol of B₅H₉. $\Delta$ H°_f[B₂O₃(s) ] = -1,273.5 kJ/mol
$\Delta$ H°_f[B₅H₉(s) ] = 73.2 kJ/mol
$\Delta$ H°_f[H₂O(l) ] = -285.8 kJ/mol

A) -1,2735 kJ/mol
B) -4,543 kJ/mol
C) -18,170 kJ/mol
D) -9,086 kJ/mol
E) -8,448 kJ/mol
