1) Draw representations of both ionic solids in each set that show the relative
differences in the sizes of the four ions, the ratio of cations to anions, and the charge on
each ion; identify which ionic solid will have the higher melting temperature; and justify
your answer. (Formula units that contain two ions must be drawn as networks consisting
of twelve ions in total. Formula units that contain more than two ions can be represented
as a single formula unit.)
NaCl or KBT
NaCl or MgS
BeF2 or LiF
CaO or CaCl2
MgO or Al2O3

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
