Concept explainers
Interpretation:
From the given set of statements, the true statement/s needs to be determined.
Concept introduction:
The temperature above which gas cannot be liquefied by pressure alone is called as critical temperature. The pressure which is required to liquefy the gas at its critical temperature is called as critical pressure.
Triple point is defined as the temperature at which all phases of water such as gas, liquid, and solid occur at equilibrium. The solid form of water occurs at the temperature below the triple point.
Hydrogen bonding can be defined as the weak bond between two molecules which results from attraction between proton of one molecule and electronegative atom in another molecule.
Face-centered cubic is defined as the cubic lattice of fcc is equivalent to every eight corners of the structure.
The relation between edge length and atomic radius for fcc crystal is given by the following formula-
The structure which has lattice points at every eight corners and an atom centered in the cube is called as body-centered cubic.
The relation between edge length and atomic radius for bcc crystal is given by the following formula-

Chemistry: Principles and Reactions
- Rutile, TiO2, crystallizes in a structure characteristic of many other ionic compounds How many formula units of TiO2 are in the unit cell illustrated here? (The oxide ions marked by an x are wholly within the cell; the others are in the cell faces.) Unit cell for rufflearrow_forwardThe normal boiling point of SO2 is 263.1 K and that of NH3 is 239.7 K. At −40 °C, would you predict that ammonia has a vapor pressure greater than, less than, or equal to that of sulfur dioxide? Explain.arrow_forwardDescribe, in general, the structures of ionic solids. Compare and contrast the structure of sodium chloride and zinc sulphide. How many tetrahedral holes and octahedral holes are there per closest packed anion? In zinc sulphide, why are only one-half of the tetrahedral holes filled with cations?arrow_forward
- Calcium oxide consists of a face-centered cubic array of O2 ions, with Ca2+ ions at the center of the unit cell and along the centers of all 12 edges. Calculate the number of each ion in the unit cell.arrow_forwardAssociate each of the solids BN, P4S3, Pb, and CaCl2 with one of the following sets of properties. a A bluish white, lustrous solid melting at 327C; the solid is soft and malleable. b A white solid melting at 772C; the solid is an electrical nonconductor but dissolves in water to give a conducting solution. c A yellowish green solid melting at 172C. d A very hard, colorless substance melting at about 3000C.arrow_forwardSpinel is a mineral that contains 37.9% aluminum, 17.1% magnesium, and 45.0% oxygen, by mass, and has a density of 3.57 g/cm3.The edge of the cubic unit cell measures 809 pm. How many of each type of ion are present in the unit cell?arrow_forward
- The CsCl structure is a simple cubic array of chloride ions with a cesium ion at the center of each cubic array (see Exercise 69). Given that the density of cesium chloride is 3.97 g/cm3, and assuming that the chloride and cesium ions touch along the body diagonal of the cubic unit cell, calculate the distance between the centers of adjacent Cs+ and Cl ions in the solid. Compare this value with the expected distance based on the sizes of the ions. The ionic radius of Cs+ is 169 pm, and the ionic radius of Cl is 181 pm.arrow_forwardArrange the following substances in order of increasing strength of crystal forces: CO2, KCl, H2O, N2, CaO.arrow_forward
