Chapter , Problem 90AE(choose chapter or problem)
The ionic substance strontium oxide, \(\mathrm{SrO}\), forms from the reaction of strontium metal with molecular oxygen. The arrangement of the ions in solid \(\mathrm{SrO}\) is analogous to that in solid \(\mathrm{NaCl}\):
(a) Write a balanced equation for the formation of \(\mathrm{SrO}(\mathrm{s})\) from its elements.
(b) Based on the ionic radii in Figure 7.8, predict the length of the side of the cube in the figure (the distance from the center of an atom at one corner to the center of an atom at a neighboring corner).
(c) The density of \(\\mathrm{SrO} \text { is } 5.10 \mathrm{~g} / \mathrm{cm}^{3}). Given your answer to part (b), how many formula units of \(\mathrm{SrO}\) are contained in the cube shown here?
