The purpose of this experiment is to become familiar with some properties of water and solutions and distinguish between such terms as diffusion‚ dialysis and osmosis. In this experiment‚ we will be going over water residue‚ water of hydration‚ solutions and dialysis. For Water Residue section‚ place about 1 mL of tap water on a clean watch glass and gently heat it until water has evaporated. Record if there is any residue and repeat this procedure using deionized water. Next‚ for Water of Hydration

Global Service for Mobile Communications (GSM) has internationally appeal but is the network that Cingular and T-Mobile use for their service. Code Division Multiple Access (CDMA)‚ have better coverage in the United States and are mainly utilized by Sprint and Verizon Wireless. The newest trends plan to integrate their technologies in the cell phone industry

boiling points‚ and do not conduct electricity. Since electrons are shared in covalent bonds‚ they have slightly different properties than ionic-bonded compounds. Based on these properties‚ the best compound for your ceramic fixative would be sodium chloride (NaCl)‚ because it has an ionic bond‚ has a high melting and boiling point‚ is electrically conductive‚ dries white‚ and can dissolve in water but not in alcohol. When we conducted this experiment‚ we used distilled water to test if the compounds

3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

slower rate of movement.1 2.3. The aim of this investigation is to evaluate the process of Osmosis and Diffusion on different concentrations of sodium chloride on a de-shelled chicken egg over a period of 24 hours. 2.4. My hypothesis relating to this investigation is that the de-shelled eggs in different sodium chloride solutions will absorb the water through the process of osmosis which will cause the eggs to increase both their weight and size. 2.5. The outcome varied

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance
