To the best, of my knowledge term , hydricity was first used in 1992 for hydricity as parallel to donating ability of hydride, as parallel to acidity and parallel to nucleophilicity. After reduction with one electron hydride will have more electron density so hydride donating ability of metal hydride will increase so hydricity will increase. As hydride donating ability of metal hydride increase acidity will also increase because acidity is directly proportional to hydride donation ability. And pKa is inversely proportional to acidity so pKa will decrease

1.) Identify the most likely transition metal, M and provide a
suitable explanation:
a.) A complex ion with the formula
[M(H2O)6]3+, where M is a second
row transition metal, that has a LFSE (CFSE) of -2.4
(ignoring pairing and exchange energies). Hint: only the low
spin configuration is observed in second row transition metals.
b.) A tetrahedral complex ion with the formula
[MCl4]-, where M is a first row transtion
metal, that has five unpaired electrons.

9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...
