b. An anion of lithium-5
Explain how would expect the nonbonding electron-pair domain in NH3 to be greater or less in size than for the corresponding one in PH3
Draw the general reaction scheme for an amino acid reacting with ninhydrin and then draw the structures for each component in the solvent system of the following
If a column is exchanged for a similar column that is half the length of the first column, how would that change the retention time of a solute
When 36.5 mL of 0.585 M H2SO4 is added to 36.5 mL of 1.17 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate pH of this reaction.
The developing chamber is not covered with plastic wrap during the development of the chromatogram. Will the Dion value for the cation be greater than or less than the actual value as a result of this technique error? Explain
