Look over these statements about the chemical elements in one or more main-block groups of the Periodic Table: • Most of the elements in this group react with fluorine to form ionic compounds that are not soluble in water. • Elements in this group have one common oxidation state, which is positive. • Elements in this group are metals with the highest average melting points of all the main-group metals. • Most of the elements in this group react with oxygen to form basic oxides. Note: none of these statements apply to hydrogen, which for the purposes of this problem we leave out of Group 1A. Are all of these statements true for the same group? For example, if all of these statements are true about the elements in Group 1A, you should answer yes. But if some statements are true for the elements in Group 1A and some others are true only for elements in Group 2A, you should answer no. If you answered yes, what is the group? O yes O no

Look in Appendix D and compare the electron configurations shown there with the fusion enthalpies for the metals shown in Table 9.7. Is there any correlation between these configurations and this property? Does strength of attraction among metal atoms correlate with number of valence electrons? Explain your answers.
• Density: In both solids and liquids, the molecules are held very closely together and therefore their densities are about the same. In gases, there is space between the molecules. • Molecular movement and order: The molecules in solids are arranged in a regular pattern that does not allow for diffusion, although does allow for vibrations. The arrangement of molecules in a liquid, although not completely random, is not completely fixed. Molecules in a gas are randomly arranged and move very quickly. Gases diffuse quickly in comparison to liquids. Compressibility and thermal expansion: Since the molecules in solids and liquids are already very close together, applying pressure does not greatly affect the volume. In contrast, the space between gas molecules allows for a great deal of compressibility. Although temperature changes will cause slight variations in the volume of a solid or liquid, those variations are negligible compared to the thermal expansion of a gas. Shape and…

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure. 2. The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC. 4. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…

Write the formulas for the common oxides formed by chromium, manganese, and barium. c.) Predict the products formed by each of the three oxides in the Goldschmidt process, using a balanced chemical equation.
