Osmotic pressures are often reported in units of atmospheres or mm Hg. The latter impliesthat the height of a column of liquid can be used as a measure of pressure. This is, in fact, thebasis of the torricellian barometer from which the units of “torr” come. The pressure, P, isrelated to the height of the column by:P = ρghwhere ρ is the density of the liquid, g is the acceleration due to gravity and h is the height. Whatwill be the height (in mm) of a column of aqueous solution with a density of 0.9987 g/mL, if theosmotic pressure of the solution at 25 °C is 1.4 mm Hg? The density of mercury at thistemperature is 13.8 g/mL
When treating a mixture of metals( copper and zinc) with an excess of solution of hydrochloric acid, 2.24 liters of a gas(STP) were released. When the same mixture was treated with phosphoric acid precipitate of 93.5g is formed. Find the mass fraction of metals in the initial mixture.
In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The resulting crystals are filtered, giving a yield of 23.4– 24.0 g. (75–77%) of 4,4'-dibromobiphenyl, m.p. 162–163° (Note 4). How large of a scale can this reaction be run safely? Is it expensive?

Sulfur dioxide emissions from coal-based power plants areremoved by flue-gas desulfurization.The flue gas passes through a scrubber, and a slurry of wet calcium carbonate reacts with it toform carbon dioxide and calcium sulfite. The calcium sulfite then reacts with oxygen to form calcium sulfate, which is sold as gypsum. (a) If the sulfur dioxide concentration is 1000 times higher than its mole fraction in clean dry air (21010), how much calcium sulfate (kg) can be made from scrubbing 4 GL of flue gas (1 GL1X10^9L)? A state-of-the-art scrubber removes at least 95% of the sulfur dioxide. (b) If the mole fraction of oxy-gen in air is 0.209, what volume (L) of air at 1.00 atm and 25°C is needed to react with all the calcium sulfite?
An excess amount of Ba(NO3)2 was added to 2 liters of water at 25 oC until the solution is saturated. Because Ba(NO3)2 is only slightly soluble in water, the excess Ba(NO3)2 was filtered out to get a solid-free mixture. The proponents of the experiment thought about using the concept of colligative properties, specifically boiling point elevation, to determine Ksp. It was observed in their experiments that the solution boils at 100.15 deg C. Kb of water = 0.51 K-kg/mol. Barium nitrate dissociates using: Solve the ff: a) Amount of Ba(NO3)2 dissolved in grams. MW of Ba(NO3)2 = 261.3 g/molb) Solubility product, Kspc) Vapor pressure of the solution in kPa
In biological systems, a FACILITATED transport process is a form of _______ transport, where an important chemical component moves with the aid of a channel or similar structure. According to the course lectures, Zoom sessions, course lecture notes, and/or assigned course readings, one specific example of a facilitated transport structure in the cell membrane is _________ , which aids in the movement of a particular chemical component called __________. A PASSIVE transport (or diffusion) process is one in which an important chemical component moves from where it is in concentration to where it is ________ in concentration. Meanwhile, an ACTIVE transport process is one in which an important chemical component is moved from where it is in concentration, to where it is _________ in concentration. Between passive and active transport, it is _________ transport that requires energy (of some form) to occur
