Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?
Fluoridation is the process of adding fluorine compounds to the drinking water. Fluoridated water can help decrease tooth decay in the population. A concentration of 1 ppm of fluorine is typically required to provide adequate amounts. While daily water consumption per person is 151.0 gallons, most people only consume 7.6 of this water; the rest is used for cleaning or gardening. What percent of the sodium fluoride is “wasted”?
Q.No.1 The techniques like filtration and centrifugation are being used for separation of various chemical substances in solutions . Which one is more important among both of these technique and how ?.
During a laboratory experiment, a student mixed two homogeneous aqueous solutions. After mixing a solid precipitate was formed. What is the best way for the solid to be separated from the solution? Put it in a beaker and heat it. Filter it using a Buchner funnel, filter flask and vacuum pump. Use a pipette to remove the solid from the liquid. Scoop it out with a spatula. The solid cannot be isolated.
When you walked in to lab today, you noticed that your partner group had a 0.05432 ml mixture sample of sand and water in a beaker. When your group began the lab to separate the mixture in to different weight boats, you thought it would be very difficult to remove the sand. As a result, you added another 5.2ml of water to assist with removing it. A. Which separate method should be used to quickly and effectively separate the two substances. Explain why you chose this method. B.Determine the number of significant figures in your original sample. C.How much total mixture did you have after adding additional water.(provide the equation, calculate the answer and the final answer rounding to the correct number of significant figures.
2. Soap can be made using a variety of different fats, oils and bases. Suppose a student wanted to make a soft, liquid soap that lathers easily. What type(s) of fat/oil and base would you recommend? How would this differ from making a solid bar of soap? 3. Vegetable oils are typically liquid at room temperature, yet Crisco (which is made of vegetable oil) is solid at room temperature. Explain why/how this is the case. 4. Explain, with the use of a diagram how soap molecules work to clean “dirt” particles. 5. Amylase is a natural enzyme found in saliva. Describe this enzyme’s function. 6. Lactose is a sugar found in milk and other dairy products. Explain how it is broken down in most individuals. Explain lactose “intolerance”.
Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20oC is 54.6 g/100 g. At 80oC, its solubility is 66.1 g/ 100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20oC. a. Is the mixture homogeneous? If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? b. How many more grams of magnesium chloride are needed to make a saturated solution at 80oC?
More than 40% of the world's population has limited access to clean water. One proposed method for the production of clean water involves removing salt from seawater. Which technique would be used to separate the salt from the saltwater mixture?
