Based on the following data, what is the X-X bond energy? H2la) + X-le)+2HX(e): AH--150 kJ Bond Enerey (KJ/mol) HH 436 Bond H-X 431 Recall that, in general, AH-(sum of bond enthalpies for bonds broken) – (sum of bond enthalpies for bonds formed) O - 276 kJ/mol O +138 ki/mol +276 kJ/mol -138 k/mol +300 k/mol Previous

I need help calculating the enthalpy of the reaction and whether the reaction is endothermic or exothermic.

How much energy (in kJ) is required to separate (break) one mole of H-H bonds? Bond Length (pm) Energy (kJ/mol) H-H 74 436 H-C 106.8 413 H-N 101.5 391 H-O 97.5 467 O A) +436 kJ B) -436 kJ O C) +74 kJ D) -74 kJ E) 106.8 kJ

6. Use values for bond enthalpies from TCHO estimate AH for the following reaction. 3 НС OH д 'Cl 3 H₂C 'CI ОН НО OH

Use bond energy values to estimate Delta H for each of the following reactions. Bond Bond Energy (kJ/mol) C---N 891 C-N 305 H-H 432 C-H 413 N-H 391
