Assume that before separation, the pressure at the bottom of the milk bottle is Pmix. How does the pressure atthe bottom of the milk bottle after separation, psep, compare to Pmix? For simplicity, you may assume that theweight and density of the cream is negligible compared to that of the milk.► View Available Hint(s)Psep > PmixPsep = - PmixPsep Pmix In the 1950s, fresh unhomogenized milk in glass bottles was delivered to suburbanites' back doorsteps well beforedawn. When delivered, the milk was thoroughly mixed, so that it appeared homogenized, but anyone rising muchafter sunrise would find that the milk had separated, the cream having risen to the top.(Figure 1)Cream and milk are immiscible (like oil and water), and the total volume of liquid does not change when theyseparate. The top part of the bottle was intentionally given a much smaller diameter than the bottom, so that thecream, typically 3 percent of the total volume, occupied much more than 3% of the total vertical height of the milk-bottle. For this problem, assume that the total height of the milk bottle is h and the depth of the cream layer is d.Figure1 of 1hMixedhSeparated

Given the following solubility curves, answer the following questions: (a) In which of the two compounds can more solute be dissolved in the same amount of water when the temperature is decreased? (b) At what temperature is the solubility of both compounds the same? (c) Will an increase in temperature always increase solubility of a compound? Explain.
A solution is defined as a homogeneous mixture. Is a small sample of air a solution? Is the atmosphere a solution?
solution is a homogeneous mixture. Can you give an example of a gaseous homogeneous mixture? A liquid homogeneous mixture? A solid homogeneous mixture?
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”?
Sam drops a sugar cube into a jar with hot water and a sugar cube into a jar with cold water. Both jars have the same volume of water. He drops the sugar cubes at the same time and then observes how much of them dissolves in two minutes. What will be the result of Sam’s experiment, and which statement should he use as his conclusion? A A greater amount of sugar dissolved in hot water because temperature is directly proportional to the solubility rate of sugar in water. B Temperature does not affect the solubility rate of the sugar cube in water because sugar dissolves equally in both cold and hot water. C A greater amount of sugar dissolved in hot water because temperature is inversely proportional to the solubility rate of sugar in water. D A smaller amount of sugar dissolved in cold water because temperature is inversely proportional to the solubility rate of sugar in water.
Which of the following is a physical process of water purification which separates suspended solid from liquid? * a. Filtration b. sedimentation c. distillation d. all of these
A doctor has ordered that a patient be given 20g of glucose, which is available in a concentration of 75.00g glucose/1000.0 mL of solution. What volume of solution should be given to the patient?
A student believes she is observing a chemical reaction when pure sugar is burned and caramelizes. How can the student tell that a chemical change has really occurred? a. by comparing the solubility of each in water b. by comparing their volumes c. by comparing their masses d. by comparing whether each are in the solid, liquid, or gas phase
The maximum level of lead allowed in drinking water is 15mg/kg. What is this concentration in units of parts per million?
Give an example of a mixture in which solute is solid and solvent is liquid.
When using a volumetric flask, is it important to prepare solutions at room temperature? a.It's not important since the change in volume over temperature is insignificant b.It’s not important since the pyrex glass is heat- and cold-resistant and won’t change volume c.It’s important because solutions change densities with respect to temperature d.It’s important because hot or cold solutions can evaporate or precipitate
The dictionary defines homogeneousas “uniform in compo-sition throughout.” River water is a mixture of dissolved com-pounds, such as calcium bicarbonate, and suspended soil particles. Is river water homogeneous? Explain
