Question

Pentaborane-9(B5H9) IS a colorless highly reactive liquid that will burst into flames when exposed to oxygen.The reaction is '
2B5H9(l)+ 12O2--> 5B2O2(s)+9H2O(l)
Calculate the kilojoules of heat released per gram of the compound reacted with oxygen.The standard enthalpy of formation B5H9 is 73.2kJ/mol

Answer 1

delta H/g = 73.2 kJ/mol x (2 mol/rxn) x (1g/molar mass B5H9)= ?
