A fly ash aerosol of monodisperse particles with a density of 2.0 g/mL and particle diameter of 10.0 mm has a concentration of 1000.0 mg/m3. Calculate the settling velocity in cm/s and the settling rate in g/m2-s. Please answer very soon will give rating surely
Procedure: analytically transfer between 0.4053g of iron(III) chloride hexahydrate, FeCl 3•6 H2O (M = 270.2957g•mol-1), and dissolve in 5.5 mL distilled, deionized water. Support the tube on a stir plate and over a 15-minute period add, using the 10mL burette, 5mL of a nominal 600mM solution of 2,4 pentandione in methanol under constant stirring. To the resulting solution, add via a 10mL burette 3mL of a nominal 450mM sodium acetate solution stirring constantly. At this point, a red crystalline solid should begin to precipitate.
