c. only the magnitude of adhesive forces between the liquid and the tube Although chlorine has a higher electronegativity and smaller atomic radius than bromine, caesium has an even larger atomic radius than potassium (relative to the size difference between chlorine and bromine) as well as a lower electronegativity than potassium. Explain your answer. Water contains hydrogen atoms that are bound to a highly electronegative oxygen atom, making for very polar bonds. c. Capillary action ii) Viscosity increases as molecular weight increases. If one-eighth of the tetrahedral holes are filled, there is one [latex]\ce{Co}[/latex] ion for each four oxide ions. b. extreme brittleness What does this suggest about the polar character and intermolecular attractions of the three compounds? Select one: A particular pressure cooker has a safety valve that is set to vent steam if the pressure exceeds 3.4 atm. Water rises in a glass capillary tube to a height of 17 cm. When the liquid is sprayed on the skin, it cools the skin enough to freeze and numb it. The delta symbol is used to indicate that the quantity of charge is less than one. The polar fraction, at O, will bond with H of HO, so the force will be H bond.

Although steel is denser than water, a steel needle or paper clip placed carefully lengthwise on the surface of still water can be made to float. All of these factors will affect the lattice energy and therefore the melting points. When is the boiling point of a liquid equal to its normal boiling point? Identify two common observations indicating some solids, such as dry ice and mothballs, have vapor pressures sufficient to sublime? sulfurous acid, H2SO3 The two C-Cl bond dipoles have a resultant that bisects the Cl-C-Cl bond angle. b. natural gas flames don't burn as hot at high altitudes Why, the charges are indeed similar, but the distances between them are not. An atom or molecule can be temporarily polarized by a nearby species. d. F2 Select one: London forces are induced, short-lived, and very weak. Thus, it will be an ion-dipole force. The coordination number is therefore 12. e. RbI, The unit cell with all sides the same length and all angles equal to 90o that has lattice points only at the corners is called __________ . d. an instantaneous dipole and an induced dipole What is the formula of this iodide? d.

These X-rays are diffracted at an angle of 7.75 by planes with a separation of 2.64 . lower. Graphite is the most stable phase of carbon at normal conditions. A typical hydrogen bond is about \(5\%\) as strong as a covalent bond. Use MathJax to format equations. Explain why liquids assume the shape of any container into which they are poured, whereas solids are rigid and retain their shape. Explain why. A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. a) 3.80 x 102 b. its triple point occurs at a pressure below atmospheric pressure a. vapor pressure e. 2, A solid has a very high melting point, great hardness, and poor electrical conduction. b) 21.3 b. XeF4 An example would be a bond between chlorine and bromine (\(\Delta\) EN \(= 3.16 - 2.96 = 0.20\)). The H-bonding is between the [latex]\ce{N-H}[/latex] and [latex]\ce{C=O}[/latex]. a. excellent electrical conductivity Intermolecular forces are particularly important in terms of how molecules interact and form biological organisms or even life. copper (s) b.) a) ionic For example, the electron cloud of a helium atom contains two electrons, and, when averaged over time, these electrons will distribute themselves evenly around the nucleus. a. decreases nonlinearly with increasing temperature e) 82.7, How high a liquid will rise up a narrow tube as a result of capillary action depends on _______ . In a closest-packed array, two tetrahedral holes exist for each anion. Why is the melting point of PCl3 less than that of PCl5? e) 1 Pa, The vapor pressure of a liquid ___________ . The net result is rapidly fluctuating, temporary dipoles that attract one another (e.g., [latex]\ce{Ar}[/latex]). b. What is the empirical formula of the compound? It is a type of chemical bond that generates two oppositely charged ions. Suggest an explanation. Distinguish between the following three types of intermolecular forces: dipole-dipole forces, London dispersion forces, and hydrogen bonds.
