Ahypothetical metal m forms the following complexes with the generalized ligands x, y, and z: complex ion observed color [m(x)6]3+ green [m(y)6]3+ blue [m(z)6]3+ yellow order these ligands according to their ability to split d orbitals. in other words, set up a spectrochemical series, from strongest to weakest ligand field strength. rank from strongest to weakest ligand field strength.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
