Explain why the fluoride ion of the terabutylammonium flouride is more nucleophilic than the fluoride ion of sodium fluoride. Draw reaction-energy diagrams. Define the term, "diastereospecific reaction," and give a representative example.
Determine the pH at the equivalence (stoichiometric) point in the titration of 52.8 mL of 0.537 M HNO2 by 0.350 M LiOH. The Ka of HNO2 is 4.3 x 10-4.
One gallon of diesel fuel contains about 1.44E8 J of useful energy. The battery in a mobile phone contains about 15300.0 J of energy when fully charged
Consider the following reaction. N2 + 3 H2 → 2 NH3 . 28.0 grams of N2 and 5.04 grams of H2 are reacted, producing 17.8 grams of NH3. What is the percent yield?
