One molecule of affibodyreversibly binds to one molecule of bap1 to form an affibody-bap1complex. you add 75pmoles of affibodyand 20pmoles of bap1 to a test tube with 3ml total volume. 36hours later, you measure the amount of affibody—bap1complex to be 4pmoles. a. assuming an association rate constant of 2x105m-1s-1, calculate the dissociation rate constant. b.how much additional affibodywould need to be added to achieve 10 pmoles of affibody—bap1complex at equilibrium? assume the affibodysource is highly concentrated such that you can neglect the change in volume upon affibodyaddition. c.recalculate the solution to part bif the affibodysource is present at500 nm, so that you cannot neglect changes in volume upon addition. what was the % error in part b?

Which is true of transition metals when moving from left to right on the periodic table? the d sublevels are not filled across the period. the cation radii become larger across the period. atomic radii increase slightly and then start to decrease. atomic radii decrease slightly and then start to increase. o

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

Will give imagine you are given a mystery element. it is, however, a discovered and known element. you may perform a maximum of two observations or tests to determine its identity. time and money is critical, so you need to prioritize your tests. if you can get by with a single test, you get 100 super-geek points from your research lab team. pick your two tests, number them as #1 and #2, and justify why you think these two will certainly be enough (and why the first might well be enough all by itself.) the available tests are classification into metal, non-metal, or metalloid, count of valence electrons, count of electron shells, atomic radius (error range: +/- 1 pm), electronegativity (error range: +/- 0.1), first ionization energy (error range: +/- 10 kj/mole), melting point (error range: +/- 10 c), and boiling point (error range: +/- 20 c).
