Which half-reaction correctly represents reduction? a) ag -> ag+ + e– b) f2 -> 2 f– + 2e– c) au3+ + 3e– -> au d) fe2+ + e– -> fe3+

Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of c6h13br and two stereogenic centers. indicate chirality by using wedge and hashed wedge notation. lone pairs do not need to be shown.

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
