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),…Q1 Solid matter held in place by electrostatic attraction forces between positive ions and a "sea" of freely moving electrons describes what type of bonding? ionic covalent metallic hydrogen Q2 A certain mass of nitrogen gas occupies a volume of 1.55 L at a pressure of 5.65 atm.

- • 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…Write the law for this reaction and explain how it is determined SO2CL2 ->SO2 + CL21. What is the difference between conductivity of solutions and metallic conductivity?
