A ligand must have a lone pair of electrons to donate to the transition metal. Usually, drawing a Lewis structure is the best way to determine whether a compound has a lone pair. Draw the Lewis structure of BF₃. Can this molecule act as a ligand?

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
