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/ The atomic radius of BCC Cesium is 0.265 nm, and the atomic mass is 132.91 g/mol, determine the number of vacancies needed for a BCC Cesium crystal to have a density of 1.83 g/em'.Why is the boiling point of the halogen in each period greaterthan the noble gas?
