Values of measured bond energies may vary greatly depending on the molecule studied. Consider the following reactions: N C l 3 ( g ) → N C l 2 ( g ) + C l ( g ) Δ E = 375 k J / m o l O N C l ( g ) → N O ( g ) + C l ( g ) Δ E = 158 k J / m o l Rationalize the difference in the values of ∆ E for these reactions, even though each reaction appears to involve only the breaking of one N—Cl bond. (Hint: Consider the bond order of the NO bond in ONCl and in NO.)

How would you prepare 1 liter of a 50 mM Phosphate buffer at pH 7.5 beginning with K3PO4 and 1 M HCl or 1 M NaOH? Please help and show calculations. Thank you
Draw the four most importantcontributing structures of the cation intermediate thatforms in the electrophilic chlorination of phenol,(C6H5OH) to form p-chlorophenol. Put a circle aroundthe best one. Can you please each step and also how you would approach a similar problem. Thank you!
A 100mM lactic acid/lactate buffer was found to have a lactate to lactic acid ratio of 2 and a pH of 4.2. What is the pKa of lactic acid? Can you please help show the calculations?
