10mL gaseous C_(4)H_("x") required exactly 55mLO_(2) for complete combustion.What is the value of "x"
For the reaction N_(2)+3X_(2) to 2NX_(3) where X=F, Cl (the average bond energies are F-F = 155 kJ "mol"^(-1) N-F = 272 kJ "mlo"^(-1) , Cl-Cl = 242 kJ "mol"^(-1) , N-Cl= 200 kJ "mol"^(-1) and N -=N = 941 kJ "mol"^(-1) ), the heats of formation of NF_(3) and NCl_(3) in kJ "mol"^(-1) , respectively, are closest to
