Draw the structural formula of a tetrapeptide Alanine-Lysine-Asparagine-Phenylalanine. Start the N- terminal on the left and end with the C-terminal on the right. Assume that the pH of a solution is 7.00.
The creation of a weak acid titration plot is described in chapter 10-5 of your technique book. A generic four-step procedure is given. Rewrite the four steps to be a specific prcedure to be used to titrate a sample of potassium hydrogen phthalate (MM 204.22 g/mol). Include the specfic amounts of materails you […]
Calculate the average atomic mass in units of amu for iron (Fe) given that the naturally occurring element exists mainly as a mixture of Fe-56 (91.754%0), Fe-54 (5.845%), and Fe-57 (2.119%). Does your value agree with that shown in the periodic table?
According to Hund’s rule of maximum spin multiplicity, how many singly-occupied orbitals are there in the valence shells of the following elements in their ground states? Enter your answer as the sum of all the orbitals (for example 15). A) iron B) neon C) nitrogen D) gallium E) phosphorus […]
