Use the relative ionic radii in Fig. 13.8 to predict the structures expected for CsBr and KF. Do these predictions agree with observed structures? The ionic radius of Cs+ is 169 pm.
Answer to relevant QuestionsMnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47 × 10–8 cm, and the density of MnO is 5.28 g/cm3. a. Does MnO crystallize in the NaCl type or the CsCl type ...Perovskite is a mineral containing calcium, titanium, and oxygen. The following diagrams represent the unit cell. a. What is the formula of perovskite? b. An alternative way of drawing the unit cell of perovskite has calcium ...Carbon tetrachloride (CCl4) has a vapor pressure of 213 torr at 40oC and 836 torr at 80oC. What is the normal boiling point of CCl4? Consider a 75.0-g sample of H2O(g) at 125oC. What phase or phases are present when 215 kJ of energy is removed from this sample? (See Exercise 91.) Like most substances, bromine exists in one of the three typical phases. Br2 has a normal melting point of 27.2oC and a normal boiling point of 59oC. The triple point for Br2 is 27.3oC and 40 torr, and the critical point is ...
