Chapter 1, Problem 3P

Justify the polymerization of vanadates VO43-, as a function of concentration and pH.

What is the preparation of 500 mL of 100mM MOPS buffer (pH=7.5) starting with 1 M MOPS and 1 M NaOH? How would I calculate the math?

Indicate the correct option.a) Isopolianions are formed around metallic atoms in a low oxidation state.b) Non-metals such as N, S, C, Cl, ... give rise to polyacids (oxygenated).c) Both are incorrect.

5. Draw molecular orbital diagrams for superoxide (O2¯), and peroxide (O2²-). A good starting point would be MO diagram for O2 given in your textbook. Then: a) calculate bond orders in superoxide and in peroxide; indicate which species would have a stronger oxygen-oxygen bond; b) indicate which species would be a radical. (4 points)
