Consider the following reaction:H2 (g) + O2 (g) --> H2O2 (g) (Delta)H = -153 kJGiven that the H2 bond energy is 432 kJ/mol, the O2 bond energy is 495 kJ/mol, and the OH bond energy is 467 kJ/mol, estimate the bond energy for the oxygen-oxygen single bond (in kJ/mol).
“Inert” xenon actually forms several compounds, especially with the highly electronegative elements oxygen and fluorine.The simple fluorides XeF₂, XeF₄, and XeF₆ are all formed by di-rect reaction of the elements. As you might expect from the sizeof the xenon atom, the Xe-F bond is not a strong one. Calcu-late the Xe-F bond energy in XeF₆, given that the heat of for-mation is 402 kJ/mol.
