The trans-planar configuration of the Hydrogen peroxide molecule (H2O2) belong to C2h group of Symmetry. Determine the normal modes of vibrations? show your work in detail starting with the reducible representations

Magnesium is an important element in the human body, especially in bones. Magnesiums atomic number is 12. Is it stable or reactive? Why? If it were to react with another atom, would it be more likely to accept or to donate one or more electrons?

The synthetic process by which monomers are covalently linked is (a) hydrolysis (b) isomerization (c) condensation (d) glycosidic linkage (e) ester linkage

MATHEMATICAL Show that, for a pure weak acid in water, pH=(pKa2log[HA])/2.

What are Okazaki fragments and how they are formed?

MATHEMATICAL Consider the reaction AB+C, where G=0.00. (a) What is the value of G (not G) when the initial concentrations of A, B, and C are 1 M, 103M,and106M? (b) Try the same calculations for the reaction D+EF, for the same relative order of concentrations. (c) Try the same calculations for the reaction GH, if the concentrations are 1Mand103M for G and H, respectively.

What are some of the ways that the features of carbon-to-carbon bonds influence the stability and 3-D structure of organic molecules?

MATHEMATICAL A catalog in the lab has a recipe for preparing 1 L of a TRIS buffer at 0.0500 M and with pH 8.0: dissolve 2.02 g of TRIS (free base, MW=121.1 g/mol) and 5.25 g of TRIS hydrochloride (the acidic form, MW=157.6 g/mol) in a total volume of 1 L. Verify that this recipe is correct.

MATHEMATICAL Catalase breaks down hydrogen peroxide about 107 times faster than the uncatalyzed reaction. If the latter required one year, how much time would be needed by the catalase- catalyzed reaction?

RECALL Match the following statements about protein structure with the proper levels of organization. (i) Primary structure (ii) Secondary structure (iii) Tertiary structure (iv) Quaternary structure (a) The three-dimensional arrangement of all atoms (b) The order of amino acid residues in the polypeptide chain (c) The interaction between subunits in proteins that consist of more than one polypeptide chain (d) The hydrogen-bonded arrangement of the polypeptide backbone.
